Abstract:
The gas pipelines usually undergo complicated and changeable regional environment. As the level of the potential difference or pipeline’s route changes in the space and therefore elastic bending cannot meet the needs when pipe changes its direction, we generally use pipe bend to connect two pipelines with different spatial extend direction during the pipe laying period, and it can reduce the temperature stress. Unreasonable design of elbow will lead to pipeline damage. We established mountain area pipeline model, and conducted analysis on pipeline stress under different elbow angles. Research shows that different angles of the bends suffer different operation stress, and we have come to the conclusion that the angle of pipe bends should not be within the range of 15 degrees to 35 degrees.

Abstract:
With continued urbanization in China, the construction of urban gas pipelines is increasing, and the safety of gas pipelines are also increasingly affected by urban development and the increased scope of buildings and roads. Pipes with defects are more likely to fail under the surface loads. In this study, uniaxial tensile tests of high-density polyethylene (HDPE) pipes were carried out to obtain the real material parameters of pipe. A pipeline-soil interaction finite element model of HDPE pipeline with defects under surface load was established. The failure mechanism of the urban gas pipeline was studied and the influence of parameters such as internal pressure, defect position, defect depth on the mechanical behavior, and failure of pipelines were analyzed. A failure criterion for HDPE pipes with defects under surface load was proposed based on the limit-state curves obtained under different working conditions. Furthermore, an accurate and efficient fitness-for-service assessment procedure of pipes with defects under surface load was proposed. The results showed that maximum Mises stress of the pipeline gradually increased with increasing surface load and the position of maximum stress changed from the top and bottom of the pipe to the defect position and both sides of the pipe. Finally, when Mises stress of the HDPE pipe exceeds the yield limit, failure will occur. Internal pressure, defect location, and defect depth were found to influence the failure process and critical surface load of the pipeline. Safety evaluation curves of the gas pipeline with defects under surface load were obtained by calculating the critical failure load of the pipeline under various working conditions. Finally, a nonlinear fitting method was used to derive a formula for calculating the critical surface load under different defect parameters. The proposed method provides a useful reference for urban gas pipeline safety management.

Abstract:
When the shock wave caused by explosion in geotechnical medium encountered buried pipeline, the buried pipeline may be destroyed. Use the LS-DYNA program to describe the deformation of buried pipelines under explosion ground shock. The results indicate that the process of the stress on pipe is instantaneous, and the back of buried pipelines against explosion center suffers greater instantaneous pulling stress in axis direction. The stress on the pipes, which is brought by the weaponary explosion, is involved with the distance between the pipe and explosion center and the diameter of pipe, among which the former involves greater. And the smaller pipe would get greater shock.

Abstract:
Long-term operation of main gas pipelines, the presence of water and mechanical impurities in the transported gas lead to erosion and corrosion damages to the inner surface of pipes, which causes an increase in its roughness. The increase in roughness results in an increase of the hydraulic resistance of natural gas pipelines, as well as affects theirs transport and energy consumption parameters. To manage the regimes of operation of main gas pipelines it is necessary to adequately predict their flow capacity and energy consumption for natural gas transportation under real values of pipe roughness which is higher than designed ones. On the basis of gas-dynamic equations of the steady-state gas movement the regularities of the influence of the pipe surface roughness on the hydraulic energy consumption of gas transportation at constant gas flow in the section of the gas pipeline are established. The regularities of the influence of the pipe surface roughness on the hydraulic efficiency coefficient of the gas pipeline section under idem difference of squares of inlet and outlet gas pressure values are clarified. It is established that the value of hydraulic efficiency coefficient of the gas pipeline section for specified value of absolute equivalent roughness of the pipe surface actually does not depend on the pipe inner diameter and slightly depends on the flowrate in the gas pipeline. The method of capacity and energy efficiency determination of the gas-dynamic system called compressor station – pipeline section for the increased pipe inner surface roughness in comparison with its designed value is proposed. The method involves mathematical modelling of gas-dynamic characteristics of centrifugal compressors, thermohydraulic calculation of the pipeline section taking into account the actual roughness of the pipe, consideration of pressure and gas flowrate technological limitations as well as energy consumption determination taken per unit of work lost in transport

Abstract:
The residual strength and technical condition of the material of 530-mm steel pipe (14KhGS) of main gas pipeline are estimated to ensure the safety of long-term operation of pipelines in climatic conditions of the North. The mechanical properties are determined using standard methods of mechanical testing in laboratory conditions. A full-scale pressure test up to failure is used to determine the actual values of the fracture toughness and safety factor of the pipe. Full-scale tests were carried out on a test bench, a computer-measuring complex which displayed the reaction of the object to the load. A pipe fragment was cut from the linear part of the main gas pipeline and welded with spherical plugs. The outer surface of the pipe was notched along the pipe axis. The depth of the notch was calculated such that the breaking load on the ligament section at the notch site corresponded to the working pressure of the gas pipeline. No significant changes in the mechanical properties of the pipe metal were revealed in the absence of visible corrosion and deformation damage during long-term operation of the pipe in the North. Impact tests did not reveal embrittlement of the metal of the tested pipes. Full-scale tests of a pipe with an artificially applied defect made it possible to calculate the value of the critical stress intensity factor, which allowed us to estimate the residual strength of a pipe with a longitudinal crack. The value of the strength criterion of the fracture mechanics indicates the preservation of a sufficiently high viscosity of sheet metal pipes. Similar tests of the pipes (of other size and made of other materials) operating in the main gas pipelines should be continued taking into account temperature ranges and material degradation after long-term operation.

Abstract:
One of the most important factors that may cause a buried steel pipeline to reach the failure limit is the permanent ground displacement. In this paper, assuming SHELL element for pipeline and SOLID element for soil and also considering the interaction of pipe-soil, analysis of buried pipelines crossing fault and parametric study of pipeline behavior were performed. The results of this study show that the behavior of buried pipelines crossing fault is not sensitive to the pipe-fault crossing angle. The main reason for this is the immense strain of the pipe due to the section deformation and local buckling of the pipe body that is caused by the permanent ground displacement. The strain from this phenomenon is so great that the pipe-fault crossing angle cannot have much effect on it. The research also shows that it is better to consider pipe bending than dealing with the pipe-fault crossing angle, because it is a more important parameter in the behavior of buried pipelines crossing faults, and it has a meaningful relationship with the reached maximum strain in the pipeline.

Abstract:
Two full-scale ductile fracture propagation experiments on segments of line pipe pressurized with nitrogen gas have been conducted underwater at a depth of 40 ft (12 m) to evaluate the ductile fracture phenomenon in underwater pipelines. The pipes were 22-in. (559-mm) diameter and 42-in. (1067-mm) diameter. Fracture velocities were measured and arrest conditions were observed. The overpressure in the water surrounding the pipe resulting from the release of the compressed nitrogen gas contained in the pipe was measured in both experiments. The overpressure in the water reduces the stress in the pipe wall and thus slows down the fracture. In addition, the water surrounding the pipe appears to be more effective than soil backfill in producing a slower fracture velocity. Both of these effects suggest a greater tendency toward arrest for a pipeline underwater than would be the case for the same pipeline buried in soil onshore. Further verification of this effect is planned and a modified version of the existing model for predicting ductile fracture in buried pipelines will be developed for underwater pipelines.

Abstract:
This paper presents a numerical investigation on six pipeline models to study the seismic response of single and double buried pipelines using finite element method. Different depth and spacing of pipes are considered to investigate their prominent role in the seismic response of buried pipelines under an earthquake loading having PGA of 0.2468 g. In case of single pipeline, the maximum magnitude of final displacement as well as the stress at the end of the seismic sequence is found at the burial depth equal to the pipe diameter. In case of double pipeline, the maximum magnitude of final displacement is found when the spacing between pipes is equal to half the pipe diameter and there is an increasing tendency of developed stress with increase in spacing between pipes. In addition to the above results, the response of the buried pipelines with a particular bend angle (artificially induced bend/buckle) to the permanent ground deformation which is assumed to be the result of seismic wave propagation has also been studied. Remarkable differences in these results are obtained and with these results the designers can reduce seismic risk to their buried pipelines by taking proper precautionary measures.

Abstract:
Low carbon (~0.34 at.%) pipeline steels with high strength and high toughness are widely used for the transportation of petroleum and natural gas. These pipelines usually experience UOE (bending by U press, forming by O press, Expansion) piping followed by coating process at 250°C, which usually cause strain aging phenomenon with discontinuous yielding in service. In order to understand the major cause of the strain aging in these low carbon pipeline steels, the dislocations associated with solute carbon atoms have been investigated in three different types of steels (plate, pipe, and coated pipe). In-situ TEM heating up to 250°C for 30min did not cause any change of structure in both steel plate and pipe. However, APT results revealed the segregation of carbon atoms alone dislocation lines in ferrite region of both UOE pipes and coated pipes. It is believed that this solute segregation along the dislocations is the major cause in the case of strain aging of low carbon pipeline steels.

Abstract:
The objective of this Thesis is to devise a system for the "rheology-based design" of non-settling (homogeneous) slurry pipelines that is more conducive to application by practicing engineers without impairing its accuracy or utility for research purposes. The cornerstone is the development of a new rheological model and constitutive equation for homogeneous slurry based on the aggregation/deaggregation of the suspended mineral particles. This “yield plastic” model is shown to describe a family of models that includes the Newtonian, Bingham plastic and Casson models as special cases. It also closely approximates the results of many consistency models, including power law, yield power law, Cross and Carreau-Yasuda. The yield plastic model is then used to develop design equations to determine the pressure-gradient of laminar and turbulent pipe flow. A relative energy dissipation criterion is proposed for the laminar-turbulent transition and shown to be consistent with currently used transition models for Newtonian and Bingham fluids. Finally, a new dimensionless group (the “stress number”) is proposed that is directly proportional to the pressure-gradient and independent of the velocity. When the design equations are presented graphically in terms of the stress number and the plastic Reynolds number, the resulting “design curve diagram” is shown to be a dimensionless (pressure-gradient vs. velocity) pipe flow curve. The net result is that the hydraulic design of homogeneous slurry systems only requires the use of a single constitutive equation and three engineering design equations. The results are presented in a conceptually easy form that will foster an intuitive understanding of non-Newtonian pipe flow. This will assist engineers to understand the impact of slurry rheology when designing, operating and troubleshooting slurry pipelines and, in the future, other slurry related processes.

Scour is a major threat to deep water pipelines. A study was performed to determine the relationship between pipe geometry and scour depth, and examine scour hole dimensions under multiple pipes. Model tests were conducted in a two-dimensional wave-current flume facility in which pipes were exposed to unidirectional flow and unidirectional flow with oscillatory motion. The model testing investigated pipes in contact with a sand bed and the effect of pipe spacing on scour. Scour hole profiles were measured and plotted to show the scour hole shape under multiple pipe systems. For two pipe systems, spacing between pipes of 1/2 pipe diameter resulted in less scour depth than full diameter spacing. Unidirectional flow with oscillatory motion resulted in less scour than unidirectional flow. Keywords: Marine engineering; Ocean currents; Stress mechanics; Underwater structures. (KT)

Abstract:
Starting with tensor calculus and the variational form of the Hamiltonian functional, a generalized theory is formulated for doubly curved thin shells. The formulation avoids geometric approximations commonly adopted in other formulations. The theory is then specialized for cylindrical and toroidal shells as special cases, both of interest in the modeling of straight and elbow segments of pipeline systems. Since the treatment avoids geometric approximations, the cylindrical shell theory is believed to be more accurate than others reported in the literature. By adopting a set of consistent geometric approximations, the present theory is shown to revert to the well known Flugge shell theory. Another set of consistent geometric approximations is shown to lead to the Donnell-Mushtari-Vlasov (DMV) theory. A general closed form solution of the theory is developed for cylinders under general harmonic loads. The solution is then used to formulate a family of exact shape functions which are subsequently used to formulate a super-convergent finite element. The formulation efficiently and accurately captures ovalization, warping, radial expansion, and other shell behavioural modes under general static or harmonic forces either in-phase or out-of-phase. Comparisons with shell solutions available in Abaqus demonstrate the validity of the formulation and the accuracy of its predictions. The generalized thin shell theory is then specialized for toroidal shells. Consistent sets of approximations lead to three simplified theories for toroidal shells. The first set of approximations has lead to a theory comparable to that of Sanders while the second set of approximation has lead to a theory nearly identical to the DMV theory for toroidal shells. A closed form solution is then obtained for the governing equation. Exact shape functions are then developed and subsequently used to formulate a finite element. Comparisons with Abaqus solutions show the validity of the formulation for short elbow segments under a variety of loading conditions. Because of their efficiency, the finite elements developed are particularly suited for the analysis of long pipeline systems.

Abstract:
The impact of a pipeline by a dropped object has been considered to consist of four distinct impact components: the dropped object, pipeline protection, the soil bed and the pipeline itself. The effect of these components as energy absorbers and the effect on system response has been investigated. Quasi-static and dynamic testing has been earned out to investigate the interaction between the various impact components. Quasi-static testing has been widely used to develop initial predictions, since closer observation of interaction is easier. The validity of applying these predictions to dynamic situations has been addressed using results from dynamic impact testing. The Dropped Object: Two areas have been investigated which address the dropped object within the impact system: the dropped object's impact profile and its deformability. Testing has been carried out to study the effect of typical loading profiles. Research has shown that the dropped object profile significantly effects the pipe response; a cone shaped indentor generates deformation with far less energy than either a wedge or a patch shape. The applicability of a method to predict the interaction between two deforming structures, using a method of shared energy, has been investigated for quasi-static and dynamic loading. During quasi-static testing it was found possible to predict a combined response using individual responses. During dynamic testing prediction was not possible, since inertia effects where found to dominate the response. The Concrete Protective Coating: A programme of work carried out has qualified the role of a pipeline protective coating and assessed the effect of four different types of concrete reinforcement. Summary Although the study has not been exhaustive, it is clear that reinforcements, which hold the concrete coating to the pipe, allow the coating to continue its protection. Fibres added to a concrete mix were found to reduce the damage to the pipe. However mesh reinforcements were found to hold the concrete together most effectively and provided the greatest added protection. The Soil Support: All foundations absorb some energy. Tests have been carried out to investigate the effect of a soil bed on the response of a laterally loaded pipeline. During dynamic tests on sand supported pipes it was noted that no energy was absorbed during the initial deformation, possibly corresponding to local indentation of the pipe wall. After this the sand was seen to react and absorbed a proportion of the energy, depending on the hammer's drop height. The energy absorbed by the soil continued to increase until an energy plateau was reached, after which the soil absorbed no further energy. It was noted that the displacement at which this energy plateau was reached increased as the drop height increased. Two possible causes of the energy plateau have been discussed. The first cause questioned an assumption that the pipe would deform as if on simple supports. The second possible cause suggested a change from dynamic to quasi-static response and investigated the relationship between acceleration, velocity and reaction force. Of the possible causes of the energy plateau, the most likely is thought to be soil related. Investigation into the Deformation of Locally Loaded Pipes: The investigation into pipeline deformation has been carried out using experimental, numerical and theoretical analysis methods. Quasi-static test results have been used to investigate four pipeline parameters and their influence on energy absorbed by the pipeline, (length, L, wall thickness, t, diameter, D and material yield stress, ay). This investigation led to an empirical equation, which brought all energy-displacement (E-8) curves on to a common curve, for a wide range of these variables. This empirical relationship has been developed to predict deformation, for the range of parameters investigated. Dynamic results obtained were normalised using these empirical equations and data was seen to fall into two broad groups, one group comprising seam welded pipe and one group comprising cold drawn pipe. Strain rate effects were proposed as the most likely cause of this bi-grouping. Limitations in the experimentally derived empirical relationship have been identified, resulting from an insufficient range of pipe samples tested.

Abstract:
A study has been performed to investigate resin cure and associated characteristics of composite used in CIPP technique (cured-in-place pipe). CIPP have been employed to rehabilitate deteriorated pipe line. Such liners are often subjected to external hydrostatic pressure which may eventually lead to creep or buckling of the liner within the host pipe. The main objectives of the research are: O To increase flexural modulus without adversely effecting the strength. O To improve the curing and thermo mechanical properties of resin-felt system. Numerous tests were performed on curing systems using DMA (Dynamic Mechanical Analyzer) technique to evaluate material cure and progression for various cataKst percentages. Gellation, vitrification, working open time and glass transition (Tg) were all assessed. A Time Temperature Transformation (TTT) profiles were proposed for three different systems of 2. 3 and 4% w/w catalyst (Figures 8.3. 8.4 and 8.6). indicating the various phases of cure progression (liquid / rubber / glassy and degradation) and further developed using DMA technique in penetration mode. The unique TTT profiles of unsaturated polyester resin in adjacent with nonwoven polyester felt developed to create the similar environment of CIPP production outside of the laboratory condition. In an attempt to enhance the physical and mechanical properties of the liner materials, many different additives were considered. However, it was found that silicon carbide (SiC) nanoparticles can potentially increase the flexural modulus and hardness of the liner materials. However due to the high cost of SiC. various amounts of crystalline SiC>2 (silica) and amorphous SiOo (rice husk ash, RHA) were used to achieve the most optimum mechanical properties. To improve the interfacial interaction between matrix and reinforcement, a suitable coupling agent was used. In the process, Differential Scanning Calorimetric (DSC) was used to evaluate the exothermic behaviour of the samples, scanning electron microscopy (SEM) was used to appraise the mechanism of failure. Thermogravimetry anahsis (TGA) was applied to measure the amount of volatility in the materials. The mechanical performance of all the samples was evaluated using flexural. microhardness, tensile, ring stiffness and creep-recovery tests. Additionally creeprecovery test yielded useful results on the shrinkage of different composite samples containing silica, SiC and RHA. It emerged that by using 8-10% w/w Silica treated by coupling agent resulted in the most cost effective solution, yielding a 30% improvement in flexural modulus of the liner material, this was found to be due to a stronger matrix-reinforcement interfacial interaction. Furthermore, thermo-mechanical properties of different polymer pipe materials used in pipe renovation, including MDPE. HOPE, U-PVC. M-PVC and PUR, were evaluated using DMA. The results of this study indicated that a developed CIPP liner made from polyester felt impregnated with unsaturated polyester resin, containing 10% SiC>2 additive (coupling agent treated) yielded the optimum mechanical performance, with a storage modulus of 1876 MPa, which is noticeably higher than that of different modern pipe materials on the market (PUR. MDPE, HOPE. PVC-U, PVC-M). This improvement in the results has been attributed to the development of optimum interfacial bond strength between silica, matrix and felt. Also this optimum formulation showed excellent toughness performance. The investigation into the thermo-mechanical properties of the optimised CIPP (UPE/F10%SP+CA samples), shows that the developed CIPP has been achieved the best performance in pipeline application.

Abstract:
Over the last few years, several advancements have been made in water and wastewater pipe renewal technologies that have allowed utilities to utilize innovative renewal techniques that decrease project costs, the impact of the project on the surrounding citizens and environment, and allow for expedited pipeline renewals compared to traditional open trench methods. The challenge now is in getting utilities to implement new innovative technologies within their system. This thesis provides background information on a number of the technologies available for the renewal of water and wastewater system pipelines. It then provides State of the Art Literature and State of the Art Practice Reviews based on technology use trends in literature and technology use trends in utility practice. The information from both reviews is then synthesized to provide a clear view of the state of the water and wastewater pipeline renewal technology industry, including the trends by pipe material, drivers for renewal, and technology type.

Abstract:
A pipe-in-pipe (PiP) technology was selected to transport hot fluids through muskeg and multiple obstacles dealt with Horizontal Directional Drillings (HDDs) in Northern Alberta. The system offers both integrity and construction advantages. • The outer pipe provides an obvious secondary barrier to any leak. It also provides the basis for a surveillance system with a sensitivity more than 1000 times the sensitivity provided by the standard mass-balance. • The system is pre-constrained: the inner pipe is pre-heated using electrical heat tracing at a temperature such that the system, once installed, has thermal stresses reduced by half and thus permits the installation of the high-temperature pipeline in non-competent soils with no expansion loop and no external anchor. • The insulation system between the two pipes reduces the heat loss to only 0.3 W/(m2.K), leading to a very long cool down time. Finally, the pipe-in-pipe can be a simple solution to high-risk and/or high scrutiny areas such as HDDs, sensitive wetlands, unstable soils, etc.

Full text
Abstract:
The increasing demand for natural gas will further influence the type of its transportation in the future, both from the strategic and economic point of view. Long-distance pipelines are a safe and economic means to transport the gas from production sites to end users. High-strength steels in grade X80 are nowadays state of the art. Grade X100 was recently developed but not yet utilised. The present-day technical limitations on the production of X120 line pipe namely the steel composition, the pipe forming and the welding are addressed in this paper. Production test results on X120 pipes are presented to describe the materials properties. A low carbon and low PCM steel with VNbTiB microalloying concept is used. In the plate rolling the main attention is turned to the heavy accelerated cooling. The large spring back that occurs during the U-forming step of the UOE process is one of the most complex aspects in forming X120. To handle this aspect FEM calculations were used to modify the forming parameters and to optimise the shape of the U-press tool. For optimising the existing welding procedure with respect to an avoidance of HAZ softening, a low heat input welding technology and new welding consumables were developed.

Full text
Abstract:
A pair of autonomous microcontroller-based robots were designed, built, and tested to inspect the inside of an 8 in pipe. The pair consists of a “scout” which travels along the inside of the pipe and scans the surface for holes using an array of touch sensors. Once a hole is found, the “scout” communicates the position of the hole to a second “mule” robot that has an on-board sealant dispensing system. After the scout moves out of the way, the mule moves to the hole location and dispenses sealant to seal the hole. Both robots are controlled by a BASIC Stamp microcontroller and propelled by servomotor driven wheels in response to sensor input. Communication is accomplished using wireless RF transceiver boards. This paper discusses the design, build, and test of these cooperative robots; the problems encountered, and how these problems were solved in order to successfully meet the project requirements of creating a two robot system that could find and simulate the sealing of holes in pipes.

Full text
Abstract:
The Gas Technology Institute is currently addressing the risks and threats to plastic pipes through research sponsored by the United States Department of Transportation, Pipeline and Hazardous Materials Safety Administration. With the upcoming proposed rulemaking, the United States distribution companies will be required to implement a distribution integrity management plan. In developing an integrity management plan, it is key to understand system risks and threats and with 39.6 million plastic services and nearly 620,000 miles of plastic gas main, the threats to plastic pipe need to be addressed. The research discussed in this paper identifies the types of failures that affect plastic piping, excluding third party damage. The paper also describes the most common cause of leaks, slow crack growth, as well as root cause analysis of a pipe removed from service due to leaking. The cause of leaks for five other pipe segments is also discussed. The final topic of this paper is rapid crack propagation and small-scale steady state testing.

Full text
Abstract:
Fossil fuel power plants are complex systems containing multiple components that create extreme environments for the purpose of extracting usable energy. Failures in the system can lead to increased down time for the plant, reduction of power and significant cost for repairs. In the past, inspections and maintenance of the plant's superheater tubes has been predominantly manual, laborious, and extremely time consuming. This is due to the pipe's small diameter size (between 1.3 and 7.6 cm) and the coiled structure of the tubing. In addition, the tubes are often stacked close to each other, limiting access for external inspection. Detection of pipe degradation, such as increased levels of corrosion, creep, and the formation of micro-cracks is possible using standard non-destructive evaluation (NDE) methods, including ultrasonic, radiography and electromagnetic methods. However, when the access to the sub-systems is limited or the configuration of the structure is prohibitive, alternative methods are needed for deploying the NDE tools. This research effort considers a novel robotic inspection system for the evaluation of small pipes found in typical boiler superheaters that have limited access. The pipe crawler system is an internal inspection device that can potentially navigate through the entire pipe length using linear actuators to grip the walls and inch along the pipe. The modular nature of the system allows it to traverse through straight sections and multiple 90-degree and 180-degree bends. The crawler is also capable of providing visual inspections, ultrasonic thickness measurements, and generating inner diameter surface maps using LiDAR (light detection and ranging). Ultimately, the development of this robotic inspection tool can provide information regarding the structural integrity of key pipeline components in fossil fuel power plants that are not easily accessible

Full text
Abstract:
Access to piped sewage in Latin America and the Caribbean (LAC) cities has been on the rise in recent decades. Yet achieving high rates of end-user connection between dwellings and sewage pipelines remains a challenge for water and sanitation utilities. Governments throughout the region are investing millions in increasing access to sewage services but are failing in the last mile. When households do not connect to the sewage system, the full health and social benefits of sanitation investments fail to accrue, and utilities can face lost revenue and higher operating costs. Barriers to connect are diverse, including low willingness to pay for connection costs and/or the associated tariffs, liquidity and credit constrains to cover the cost of upgrades or repairs, information gaps on the benefits of connecting, behavioral obstacles, and collective action failures. In contexts of weak regulation and strong social pressure, utilities typically lack the ability to enforce connection through fines and legal action. This paper explores the scope of the connectivity problem, identifies potential connection barriers, and discusses policy solutions. A research agenda is proposed in support of evidence-based interventions that have the potential to achieve higher effective sanitation coverage more rapidly and cost-effectively in LAC. This research agenda must focus on: i) quantifying the scope of the problem; ii) understanding the barriers that trigger it; and iii) identifying the most cost-effective policy and market-based solutions.

A STUDY OF COLLAPSE SUSCEPTIBILITY AND RESISTANCE OF LOADED CABLE-SUPPORTED PIPE STRUCTURE SUBJECT TO A SUDDEN BREAK OF CABLE MEMBER. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.7.

Full text
Abstract:
Cable-supported pipe system (CSPS) provides a suitable system of structure for meeting the stringent structural requirements of pipeline bridges. However, due to a composite action of cable with truss and pipe members, the sudden failure of its structural member may lead to undesired vibratory response and collapse. The occurrence of a sudden break of the CSPS structural member is characterized by spontaneous dynamics and internal force rearrangement. The present study aims to investigate parametrically the collapse susceptibility and resistance of scaled down CSPS model in the event of a sudden break of the cable member by combined experimental and numerical procedures. The displacement of the structure, the pattern of internal force rearrangement, and dynamic responses were comparatively evaluated. Experimental results depict imminent cable failure under load and attendant dynamic response, but without a total collapse of the CSPS structure. Critical members causing large dynamic response amplitudes were identified and the mitigation of collapse was evaluated. Dynamic increasing factor (DIF) methods was utilized for the evaluation of the dynamic response of the sudden cable break resulting from the pattern of responses between the cable members and the rest of the CSPS structure. Comparison with provisions in other studies shows higher values DIF of the CSPS cable members which led to proposed evaluation using dynamic factor (DF). Thus, the dynamic factors for the sudden break of various cable members along the span and the errors were also estimated considering the parametric of design variables which will enable easy utilization during the structural process of CSPS.
