Abstract:
Based on the creep model of CFST members constructed with the Elastic Continuation and Plastic Flow theory of concrete creep and the creep theory of concrete under multi-axial stresses, the paper studies the load-carrying capacity of eccentrically compressed CFST members with consideration of creep. Some eccentrically compressed CFST members’ long-term loadbearing capacity is calculated and corresponding results are compared with the load-carrying capacity without consideration of creep. According to the analysis of calculating results, it can be concluded that creep will decrease the load carrying capacity of eccentrically compressed CFST members, and it should be paid enough attentions in actual engineering.

Abstract:
Besides service loads, reinforced concrete structures in cold coastal seismic regions are subjected to multiple attacks of freeze-thaw cycles and seawater corrosion as well as the earthquake struck. An experimental study was conducted to investigate the seismic response of eccentrically loaded reinforced air-entrained concrete columns under alternative actions of freeze-thaw cycles and chloride corrosion. Results show that, after 300 times of freeze-thaw cycles alternated with 100 times of seawater immersion, the hysteretic behavior of the eccentrically loaded columns manifested an apparent asymmetric pattern. Under forward cyclic load, the existence of larger eccentric load rendered the reduction of the ultimate load and the ductility of a column by up to 20.3% and 46.05%, respectively, but it had a positive effect if reverse cyclic load was applied. The presence of eccentric load could have a considerable impact on the seismic behavior of reinforced air-entrained concrete columns served in an aggressive environment.

In the present study, buckling of eccentrically loaded nanobeams in which the load is not applied at the centroid of cross section, has been studied. Eringen’s Nonlocal Elasticity Theory has been used in the formulation of governing equation of motion of the nanobeam. Simply supported and free boundary conditions for nanobeam have been taken consideration. The effect of nonlocal parameter, eccentricity of the load, nanobeam length on the buckling deflection and critical buckling load on nanobeam have been investigated. Present results can be useful in the design of nano-structures.

Abstract:
Abstract The behavior of eccentrically loaded reinforced concrete sections depends on both the eccentricity and load value. The type of failure can be determined according to the eccentricity-thickness ratio and the applied load value. Interaction diagrams can be used for designing eccentrically loaded section, but the section dimensions are required to use these diagrams. According to the section dimensions and the load value, the type of failure and the required reinforcement can be determined from the interaction diagrams. Most design codes controls the design process to ensure ductile failure. But according to the design procedures of interaction diagrams, the failure type can’t be controlled simply. This paper aims at finding a design procedure for eccentrically loaded reinforced concrete sections that enable the designer to simply control the design process and the failure mode. The proposed design approach makes the design process more direct and simplified.

Abstract:
In the model intended for short-term loading (such as during the walking cycle) of a human synovial joint in the lower extremities, cartilage lubricated by Newtonian synovial fluid is considered to be incompressible elastic and subchondral bone is considered to be rigid. The model is non-diffusional, i.e. no interstitial fluid flow occurs across the articular surfaces. A simple plane strain case of the human ankle joint is considered. For high steady loading applied in the centre of the stationary tibial arc and for steady sliding of the talar arc, this model shows that individual physiological variations in the geometry of the articular surfaces have only a small effect on the contact stress distribution and the fluid film thickness. If this load is applied eccentrically in the tibial arc, the contact pressure distribution varies more with surface geometry, but the minimum fluid film thickness differs little from that for symmetric loading. The maximum contact pressure is placed eccentrically in this case, but its value is changed only little when compared to the central loading of the same value. In order to explain different distribution patterns of subchondral bone mineralization, it is anticipated that the total load peaks of periodic time-dependent loads are transmitted centrally in some incongruent joints and eccentrically in others.

Abstract:
Finite element analysis of pinned cold-formed plain channel columns of different width-to-thickness ratios is presented in this paper. The study is focused not only on axially loaded columns, but also on eccentrically loaded columns. The general purpose finite element software ABAQUS 6.12 was used, and the force controlled loading was adopted. Geometric and material nonlinearities were incorporated in the finite element model. The ultimate loads are compared with the direct strength method (DSM) for axially loaded columns. Also, a parametric study is done by varying the length of the column and width of the unstiffened element. It is observed that the results correlate better with the DSM values for columns having unstiffened elements of lower bf/t ratios. The change in ultimate load is studied only in ABAQUS, as the position of load moves towards the free edge and the supported edge of the unstiffened element. A parametric study is done by varying the nonuniform compression factor for the columns. It is observed that the ultimate load increases as the position of load moves towards the supported edge and it is influenced by the bf/t ratio of the unstiffened element.

Abstract:
Many buildings constructed during the middle of the 20th century were constructed with criteria that fall short of current requirements. Although shortcomings are possible in all aspects of the design, the inadequacies in terms of seismic design present a more pressing issue to human life. This risk has been seen in various earthquakes that have struck Italy recently, and subsequently, the codes have been altered to account for this underestimated danger. Structures built after these changes remain at risk and must be retrofitted depending on their use. This report centers around the Giovanni Michelucci Institute of Mathematics at the University of Bologna and the work required to modify the building so that it can withstand 60% of the current design requirements. The goal of this particular report is to verify the previous reports written in Italian and present an accurate analysis along with intervention suggestions for this particular building. The work began with an investigation into the previous sources and work to find out how the structure had been interpreted. After understanding the building, corrections were made where required, and the failing elements were organized graphically to more easily show where the building needed the most work. Once the critical zones were mapped, remediation techniques were tested on the top floor, and the modeling techniques and effects of the interventions were presented to assist in further work on the structure.

Abstract:
The aim of this work is a static analysis of the reinforced concrete frame structure loaded by the effects of seismic loading. The work deals with the solution of multi-storey reinforced concrete structure designed for common loading conditions and further for possibilities of strengthening of the structure on effect of seismic loading. In the first phase of the work, the static analysis and the design of the main load-bearing elements of the frame structure (columns and main girder) were carried out for the ultimate limit state for the standard design load. In the second phase, the static analysis of the structure for the effects of accidental actions from low and high seismicity was performed and it was assessed whether the main load-bearing elements of the structure would continue to comply. Given that the structure did not satisfy the accidental actions of seismic loading, various ways of structure strengthening were designed and analyzed for their impact on the global and local behaviour of the structure. Also the designing of additional steps for structural reliability were performed. Static analyzes were performed in Scia Engineering and RFEM Dlubal software.

Abstract:
Since the publication of Terzaghi’s theory on the ultimate bearing capacity of shallow foundations in 1943, results of numerous studies—both theoretical and experimental—by various investigators have been published. Most of the studies relate to the case of a vertical load applied centrally to the foundation. Meyerhof (1953) developed empirical procedures for estimating the ultimate bearing capacity of foundations subjected to eccentric and inclined loads. Based on the review of the existing literature on the bearing capacity of shallow foundations, it appears that limited attention has been paid to estimate the ultimate bearing capacity when the foundation is subjected to both eccentric and inclined load and the objective of present study stems from this paucity. Besides, only a few studies have been made to estimate the average settlement of embedded footings when subjected to eccentric load.In order to arrive at the objective and to quantify certain parameters, extensive laboratory model tests have been conducted to determine the ultimate bearing capacity of shallow strip foundation resting over sand bed and subjected to eccentric and inclined loads. The tests have been conducted on two types of sand i.e. dense sand and medium dense sand. The load inclination has been varied from 00 to 200 whereas the eccentricity varies from 0 to 0.15B (B = width of footing). Depth of the footing is varied from 0 to B. Traditionally,in all analysis of such problems; the line of load application is towards the center line of the footing. However, in this thesis, it is investigated for the two possible ways of load application i.e. (i) towards and (ii) away from the center line of the footing.Based on the model test results, an empirical non-dimensional reduction factor has been developed for each mode of load application. This reduction factor will compute the ultimate bearing capacity of footing subjected to eccentric and inclined load by knowing the ultimate bearing capacity of footings under centric vertical load at the same depth of footing. Similarly, neural network models have been developed under each mode of load application and combined mode of load application to compute reduction factor as described above. Finally, the developed equations are compared with the existing theories.vi In addition to bearing capacity, the settlement of eccentrically loaded embedded footings is investigated. Based on some of those laboratory test results as discussed above, an empirical procedure has been developed to estimate the average settlement of the foundation subjected to an average allowable eccentric load per unit area, where the applied load is vertical.

Meyerhof (1953) suggested an empirical procedure for estimating the ultimate bearing capacity of shallow foundation subjected to eccentric load. Based on the review of the existing literature, it shows that no experimental investigation has been done to estimate the ultimate bearing capacity of shallow rectangular foundation subjected to eccentric loads. In the present work, the model tests have been conducted to determine the ultimate bearing capacity of shallow (both surface and embedded) rectangular foundation subjected to eccentric loads. Rectangular footings of size 10cm x 20cm and 10cm x 30cm are used for load-tests in the laboratory. The tests have been conducted on dense sand. The relative density (Dr) of sand maintained during the model test is 69 %. The eccentricity varies from 0 to 0.15B with an increment of 0.05B and the depth of embedment varies from 0 to B. Ultimate bearing capacity has been found out for central as well as eccentric loading condition. An empirical equation has been developed for the reduction factor in predicting the bearing capacity of eccentrically loaded rectangular embedded foundation.

Abstract:
Since Terzaghi gives his hypothesis “Theoretical soil Mechanics (1943)”, various researches have been published their works on the ultimate bearing capacity of the foundation. Most of these works are related to vertical centric loading. A few works have also done on eccentric loading. After going through a lot of existing literature, evidence suggested that reinforcement could be an effective method to increase the bearing capacity of foundation in eccentric and centric loading. But a detailed study for eccentric loading for square footing is not done. The purpose of this work is to find the optimum value of depth ratio (u/B), (h/B), width ratio (b/B), the number of geogrid layers (N), and also the effect of eccentricity on bearing capacity of the foundation. To achieve this numerical simulation of square footing (B=3m, D=0.5m) embedded in a reinforced sand bed is carried out using OPTUM G2 software. Mohr-Coulomb material model is used in the simulation. The impact of placement depth of geogrid layer, number of the geogrids, and width of geogrid layer on bearing capacity of footing for the various eccentric load (e/B = 0, 0.05, 0.1, 0.15) are examined. The Test result shows that the optimum value of u/B varies between 0.3–0.4, the optimum value of h/B varies between 0.3-0.4, the optimum value of b/B = 7, and the optimum value of N=3 for square footing.

Based on the review of the existing literature on the bearing capacity of shallow foundations, it appears that limited attention has been paid to estimate the ultimate bearing capacity when the foundation is subjected to both eccentric and inclined load and the objective of present study stems from this paucity. In order to arrive at the objective and to quantify certain parameters, extensive numerical models have been made to determine the ultimate bearing capacity of shallow strip foundation resting over sand bed and subjected to eccentric and inclined loads. The models are made with three relative density of sand i.e. dense sand and medium dense sand. The load inclination has been varied from 0° to 20° whereas the eccentricity varies from 0 to 0.15B (B = width of footing). Depth of the footing is varied from 0 to B with an increment of 0.5B.

Based on the analysis of numerical models result, the results of medium dense and dense sand are compared with the reduction factor developed by Patra et al. (2012a, 2012b) for each mode iv of load application. This reduction factor will compute the ultimate bearing capacity of footing subjected to eccentric and inclined load by knowing the ultimate bearing capacity of footings under centric vertical load at the same depth of footing. Finally, the numerical model results are compared with the existing theories and the comparison seems to be good

Regardless of the materials for falsework, the significant attention has been paid on the critical load of the falsework at different heights, and some actual situations on the construction sites and some details of accessories are usually ignored. In design, the falsework is always assumed as following. (1) The ground base had been properly tamped, and it is unnecessary to consider its settlement. (2) On the top U-shape regulator is used, and all the loads are directly and non-eccentrically conveyed into the vertical falsework. However, the investigation on the construction sites shows that in the actual construction of the falsework, the above two terms are difficult to be as ideal as that in design. The research results indicates that in the test of long-term settlement, the critical load of the combination system of the simple door-shape scaffold with wooden shores reduced the most, the second is the heavy support frame, and the pure simple door-shape scaffold system reduces the least. In the test of instantaneous settlement, the pure simple door-shape scaffold is similar to the heavy support frame in the reduction proportion of bearing capacity. On construction sites, ground arrangement should be certainly carried out first to avoid the settlement of the ground base. If the construction sites are close to rivers or agricultural irrigation ditches, the strength reduction factor needed to bear the settlement should be taken into consideration when the bearing capacity of the falsework is being calculated. In the tests of non-coaxial vertical loads, when the external force is loaded near the vertical steel tubes on both sides of the scaffold, the pure simple door-shape steel scaffold system is similar to the combination system of the simple door-shape scaffold with wooden shores in the reduction proportion of critical loads. In the test of non-coaxial vertical load with 1/2 and 1/3 configurations, the pure simple door-shape scaffold system is less than the combination system of the simple door-shape scaffold with wooden shores in the reduction proportion of critical loads. In construction sites, if the U-shape regulator is not used on the top scaffold, engineers should make the external loads near the vertical steel tubes on both sides of scaffolds to reduce the losses of the critical loads.

The welded joints Mechanical behavior is complex, according to weld groups geometry, strength, eccentrically loaded and other factors as design considerations. This research conducted to study weld groups of steel construction the eccentrically load. Furthermore, apply the six analytical methods compared. Fillet weld analysis, there are two main methods, one is elastic method, it is an easy task to use, based on the eccentric force can be moved the center of gravity of the weld group, is resolved into a force acting though the center of gravity of the weld group and a moment. The other is ultimate design, it is complex calculations to analysis, based on the IC location depends upon the geometry of the weld group and the location and direction of the loading. Theoretically, the force equilibrium equations should be satisfied at the correct IC. Method of analysis had elastic method, instantaneous center of rotation method (IC method), AISC design tables method, Iwankiw’s method, correction Iwankiw’s method and piecewise Iwankiw’s method respectively. The IC method is the most accurate. Calculation process of the Iwankiw’s method, correction Iwankiw’s method and piecewise Iwankiw’s method are more easily than IC method. However, the most commonly used elastic method is the calculation for the most simple and conservative, but the error is the largest. AISC manuals provide the C coefficients for six specific load inclination angles only, which were derived based on the IC method. For a non-tabulated value have the tendency to linearly interpolate the C coefficient for a nonspecific angle value. However, this is not totally justifiable. Compared with other methods, correction Iwankiw’s method and piecewise Iwankiw’s method are closer IC method Based on case, engineers can be selection methods used as a reference design.

When eccentricity occurs in the plane of the faying surface, the bolt must be designed to resist the combined effect of the direct share and the additional shear from the induced moment. Two analysis methods for bolted connections of eccentrically loaded are the elastic method and the ultimate strength method. The ultimate analysis, which specified in AISC design manuals, has been used for the analysis of eccentrically loaded connections which is bolted. In the current AISC design manual, tabulated solutions for eccentric loads inclined at specified angles from vertical are provided. For the cases which inclined angles are in the range of 75°≦θ≦360°, the current AISC manual does not furnish available tables to apply. This study to evaluate the strength of eccentrically loaded connections, which are not limited to the bolt patterns listed in current AISC manuals, are presented and compared. A numerical procedure for the analysis of eccentric loads that are inclined at any angles from vertical is furnished. This will also accomplish a better solution for practicing engineer in their routine design.

Abstract:
Fiber-reinforced plastic materials are used for lightweight structural applications in engineering. This paper is intended to contribute to knowledge of the buckling behavior of glass-fiber reinforced polyester (GFRP) composite I-section pultruded columns. Columns of two different lengths: 5.5 ft and 8.33 ft were axisymmetrically or eccentrically loaded in compression, until failure and the mid-point lateral deflections were measured during loading. Euler’s theory was used to determine theoretical deflection for comparison with the experimentally determined ultimate loads in the axisymmetrically loaded columns. An equation derived from the differential equation of the deflection curve was used for comparison with the experimental load-deflection curves for the eccentrically loaded columns. Limited scanning electron microscopy was done to differentiate between the microscopic failures in I-section columns.

Abstract:
In this paper, a numerical model is presented to simulate the behavior and failure of LWRC columns subjected to eccentric compressive load at elevated temperature using the finite element code ABAQUS. Validation of the numerical model was ensured throughout comparison numerical results with the available published experimental tests results. The validated numerical model was implemented in conducting extensive parametric study to understand the effects of important parameters on the response of eccentrically compressed LWRC column at elevated temperature. These parameters include effect of increasing the concrete cover, effect of changing the exposure time, effect of increasing the exposed temperature, effect of temperature distribution around column section, effect of temperature distribution along column length, and effect of eccentricity ratio. The numerical results indicated that increasing the concrete cover of the column section results a considerable increasing of the ultimate load capacity. In addition, there is an increase in the ultimate load capacity when the temperature exposure time is reduced to the half, whereas, if the exposure period is increased to twice and three times the original exposure time, the ultimate load shows a slight decrease. Moreover, the ultimate load capacity of the LWRC column decreases when temperature is increased. Finally, the ultimate load capacity increased of the LWRC column when the temperature is distributed over larger distance of the column length

Abstract:
Paper deals with the effect of turbulence on steady state performance characteristics of an eccentrically loaded 120° single pad externally adjustable fluid film bearing. The bearing has an aspect ratio of one and operates over a wide range of eccentricity ratios and adjustments. Two load-offset positions (β/χ) of 0.45 and 0.55 are considered in the present analysis. Reynolds equation incorporated with the Linearized turbulence model of Ng and Pan is solved numerically using finite difference method. A comparative study predicts that, load capacity of a bearing operating with β/χ = 0.55 and Re = 16000 is superior for negative radial and tilt adjustment configuration of the pad.

Full text
Abstract:
The subject of eccentrically loaded conforming contacts is approached analytically under the restriction that the eccentricity is small enough to keep the contact closed. This paper advances a numerical method for contact analysis valid at any eccentricity value. An additional loop is added to the classic elastic contact solver to account for load eccentricity. The method predicts contact area and pressure distribution even when the contacting bodies lose contact in some peripheral points. Numerical results of pressure distribution for a circular flat end punch agree well with existing analytical predictions.

Abstract:
Abstract Ship scantlings are obtained through a linear elastic design framework. In relatively long ships, the mid-ship’s ultimate strength capacity must be checked whether it is below a certain level (given factor of safety). Smith’s method is based on an incremental-iterative approach where constitutive equations of idealized representative components are used to model the different involved buckling modes. The literature body neglects the local bending effect applied at the stiffener with the attached plating (considered here as the representative element). This work studies the eccentrically loaded representative element from its compressive resistance point of view. The eccentricity sources from the linear varying strain field produced as a result of pure bending of the ship’s mid-section and is relative to the location of the stiffened panel from the ship’s section Neutral Axis. Therefore, the representative element has been considered as a part of the ship’s structure and the inherent eccentricity is analytically calculated in terms of geometric and material properties. A computational study has been further performed in a non-linear finite element environment in order to figure out the effect of the eccentricity level to the ultimate compressive strength of the representative element. Geometric distortions have been also included in the FE models in order to allow for accurate strength calculations. Numerical results have shown that, in realistic proportions of large ships, the further the representative element is located from the mid-ship’s NA the smaller is the deviation from pure compressive load strength analysis results. However, for the element laying near the ship’s NA, idealized models overestimate the strength by 10% compared to realistic analytical / numerical results for the typical scantling case considered.

Abstract:
<p>Large Masonry pillar structures loaded mainly by compression and to some extent eccentrically have been an important load-bearing structure both in historical buildings and in modern buildings. Recent theoretical developments for design of masonry columns will be presented. This paper provides a brief assessment of existing calculation methods in standards/codes and principle masonry design calculations (EC6design.com) will be carried out for clarifying, which design model is governing the failure. It is nevertheless very important to understand the behavior of the failure mechanism correctly so the column is not designed on the uncertain side. The design by calculation will be compared with test results on medium scale masonry wall loaded by combined vertical and horizontal load. The existing models will be evaluated and the need for further investigations will be proposed. Further the design models will be applied on a case story of high news value.

Abstract:
<p>The existing ballastless track with wooden sleepers on the Vierendeel bridges in Mechelen will be replaced by a new slab track system with continuously welded rails across the bridge. Additionally, the rails will be positioned eccentrically on the stringers due to track optimization. This paper describes the design and implementation of this new modular track system that consists of prefabricated fully welded steel frames that are bolted onto the existing superstructure. During the design stage, focus was on the required load transfer via the steel frame to the bridge superstructure, on the large difference in steel characteristics between the old and new material and on the position of joints and fastenings. Lateral and longitudinal stiffness of the track was tested on a prototype and the final solution was already installed and successfully implemented on one bridge. In addition, field tests in relation to rail-bridge interaction have started.</p>

"Behavior of innovative T-shaped multi-partition steel-concrete composite columns under concentric and eccentric compressive loadings." In 12th international conference on ‘Advances in Steel-Concrete Composite Structures’ - ASCCS 2018. Valencia: Universitat Politècnica València, 2018. http://dx.doi.org/10.4995/asccs2018.2018.7004.

Abstract:
T-shaped multi-partition steel-concrete composite column, composed of several concrete-filled rectangular steel hollow sections, is considered as an innovative composite member with the ability to accommodate neighboring wall thickness with great easiness. This paper intends to study the behavior of this innovative composite member under concentric and eccentric compressive loadings. A finite element (FE) analysis model accounting for the influences of confinement effects, geometric and material nonlinearities is developed using the program ABAQUS. The ultimate strength and load-strain responses predicted from the analysis are validated against the test results in the experiments conducted by the authors. The comparisons indicate that the FE model reasonably estimates the responses of the concentrically and eccentrically loaded T-shaped multi-partition steel-concrete composite columns. The verified model is then utilized to numerically investigate the working mechanism of the columns. The load distribution between the infilled concrete and the steel tubes and the stress distribution of the concrete during the loading process are analyzed. Moreover, parametric studies are performed to investigate the behavior of T-shaped multi-partition steel-concrete composite columns under different loadings. The studied parameters include steel to concrete area ratio, concrete compressive strength, steel yield strength and load eccentricity. Combined with the experimental results, FE analysis and parametric studies, the design recommendations for T-shaped multi-partition steel-concrete composite columns under different loadings are proposed.
