Abstract Lateral efficiency of a building is very important in high-rise buildings, when it comes to building them on sloping ground it is highly required to design the structure for wind load and earthquake loads. The diagrid structure thus provides very high lateral stability and reduces the lateral displacement of the building. In recent years the diagrid structure has attracted many researchers and scholars due to this greater structural efficiency. Diagrid structural system has evolved to be structurally the most efficient, aesthetically pleasant and highly economical. The present paper involves the study of diagrid structure on sloping ground and comparing it with the conventional system and finding the optimum angle of diagrid on different slopes of ground. A 12- storey building is used for comparing diagrid structure and conventional structure on sloping ground, a 48 storey building is used to find out the optimum angle of diagrid on sloping ground, ETABS software Is used for modelling and analysis, response spectrum method is used for analysis, the results show that diagrid structure is more efficient than conventional structure on sloping ground, and the optimum angle of diagrid lies between 60-75° on sloping ground.

Abstract: This study draws attention on proper planning and construction practices for multi-storied buildings on sloping ground. However, in usual design practice the designers generally ignorethe behavior of the building due to the effect of sloping ground. The evaluation of a G+4 storey RCC structure on varying sloping angles (00 , 150 , 200 , 250 , 300 and 400 ) were studied and also compared with the flat surface. The evaluations of the structure were carried by the software STAAD Pro v8i to study the effect of slopes on building performance. The evaluation was done to figure out the effect of sloping ground on the forces applied on the structure. Soil interaction must be suitably believed from design point of view. The Research work triesto find the truth about the earthquake-related behavior of multi storey structures on sloping angles thinking about soil-structure interaction. The horizontal reactions, bending moment in footings and axial force, bending moment in columns were critically studied to put the effectsof different sloping ground. It has been followed that the footing columns of lower height attract more forces, because ofa big increase in their stiffness, which in turn increases the horizontal forces and bending moment. So, the section of these columns should be designed for changed forces due to the effect of sloping ground. It draws attention to the need for proper analysis and designing of the structure resting on sloping surface. Overall movement of the structure with respect to different sloping ground setups is also carefully studied.

The authors have derived the bearing capacity factor Nq on sloping ground based on the slip line method and have verified it using finite difference analysis. The bearing capacity factor Nγ on sloping ground is obtained by an iterative finite difference solution of the slip line equations, and the results are close to those from laboratory testing. Design figures for Nγ on sloping ground are prepared for rapid engineering use. For earthquake loading, the authors have applied the concept of equivalent horizontal acceleration and have derived Nq and Nγ based on slip line analysis.Key words: bearing capacity, slip line, finite difference, sloping ground, earthquake.

Wind load is one of the common loads for civil engineering structures viz. for long span bridges, tall buildings, towers and mast structures also. Wind load is acting on such structure throughout its life span. Therefore it is most important phenomenon to be taken into consideration for a structural engineer. Due to scarcity of land or due to mountainous terrains in North and North-East part of India most of the time structures are constructed on sloping grounds which is a challenge for structural engineer for analysis and design. These structures are also directly subjected to wind loads. India is also having large records of earthquake which left behind loss of many lives and heavy destruction to property and economy. Analysis of buildings in hilly regions with sloping grounds is somewhat different than the building located over a levelled ground. In present study 3D building frames of 25 storied building resting on flat terrain and sloping ground are taken into consideration. For sloping ground slopes of 20⁰,30⁰, and 40⁰ are considered. They are to be analyzed for wind speeds 39 m/s, 47 m/s and 55 m/s respectively. The modelling and analysis can be done using ETABS software which stands for extended three dimensional analysis of building system.

The Department of Transport and Main Roads (TMR), Engineering and Technology's (E&T) Geotechnical Section, have completed a research-based field trial aimed at developing a repeatable methodology to carry out geotechnical boreholes on steeply sloping ground. This has been presented in the context of slope failures, whereby the utilisation of this practise will provide subsurface information, which is directly representative of the area of interest, rather than that which is outside the landslide extent (current general practise within Australia). It is expected that the information gained from adopting this practice will enable optimum design and remediation treatments for landslides within Australia, and subsequently contribute strongly to sustainable project outcomes.

Due to rapid urbanization and economic growth there is huge demand for construction of building. Since population density is high it led to construction of buildings on sloping ground, but this sloping grounds like hilly areas are more prone to earthquake which causes severe damage of life and property. The buildings constructed on hilly areas are different from buildings constructed on flat ground buildings on hilly areas have horizontal/plan, vertical, torsional, mass and many more irregularity. The structure irregularities are considered as one of the main fundamentals of its failure. Here we have done seismic analysis of a G+9 regular RCC building, C and I shape building of floor height 3m resting on sloping ground of horizontal angle of inclination 45o on zone II, Response spectrum analysis is done for three cases that is plain building and building with shear wall and bracings for all the three buildings, after analysis the response of the structures with respect to variation in the story drift, story displacement, base shear, story shear has been recorded and will be discussed and concluded.

This thesis details the results of an investigation into the behaviour of slopes of liquefiable sand under earthquake loading and the influence of these laterally spreading slopes on inclusions such as pile foundations passing through them. A study of the behaviour of these slopes has been carried out using the techniques of dynamic centrifuge modelling. Eight tests were carried out on laterally spreading slopes and a further five on slopes containing instrumented pile foundations. Each model was subjected to a sinusoidal input motion using a Stored Angular Momentum earthquake actuator, causing liquefaction of the sand and lateral spreading of the slope. Data from instruments measuring acceleration, fluid pressure, total stress and bending moment were logged during the earthquake and analysed to reveal information relating to the performance of these slopes during earthquakes. The experiments highlighted the importance of the dilation of liquefied soil to the behaviour of liquefiable slopes. Slope movements were limited by dilation during each cycle of the earthquake which prevented significant soil flow velocities from building up and large pressures were applied to piles from the liquefied soil owing to dilation of soil close to the pile foundation. It was shown that these large lateral forces were not wholly transmitted into bending moments due to the dynamic response of the piles, but this could be the cause of significant pile damage in other situations. It was also seen that present design methods are non-conservative for both the induced bending moments and the applied lateral loads. Further research is needed to develop better design guidance for this situation. The data from these experiments was compared with the results of a number of numerical models constructed during this work in order to simplify the prediction of the behaviour of these slopes. The displacements of the slopes were compared with those predicted using a Newmarkian sliding block approach modified to include the effects of excess pore pressures. This was shown to give reasonable agreement with centrifuge data, though it requires input of a measured or predicted time-history of excess pore pressure to calculate threshold accelerations.

For analysis of braced cuts on sloping ground, this research focus on three factors of stability and variable of deep excavation such as lateral retaining wall deformation, the maximum amount of ground settlement (δh,max ), and the strut load. To combine the monitoring data and RIDO formula produce the back analysis. Simultaneously, the differences between two factors derive from the analysis of the deep ground excavation. It looks forward to find out the soil parameter of braced cuts on sloping ground or other revisional methods. According to wall deformation from the result of this research, the deformation curve of braced cuts on sloping ground tends to cantilever style. Under the result from the back analysis of RIDO formula, three significant parameters are able to influence the result of formula calculation. They are the stiffness of retaining wall (EI:0.6~0.7); the angle of friction between soil and retaining wall (δ/φ:1/3~1/2); the coefficient of sub-grade reaction (Kh:100~175 N). The result of back analysis is closer to the value of monitoring. KEY WORDS：deep excavation, retaining wall deformation, ground settlement, strut load, RIDO program.

Pile foundations are used to support a wide variety of structures. In many cases, lateral loads are often the critical factors considered in the design of piles. The response of piles subjected to lateral loading is highly nonlinear due to the inherent nonlinear behavior of soils and piles. In many practical situations, structures subjected to lateral loading are located near or in the slopes or embankments. But, the research to examine the effects of soil slope on lateral pile capacity is limited. Therefore, this study aims at the nonlinear analysis for lateral response of a pile on sloping ground. To achieve the purpose, this study developed the analytical solution to estimate the ultimate soil resistance in the lateral loaded pile located in slope. The analytical solution is assumed passive failure wedge modal, and can be applied to normal type of soils. Furthermore, this study developed a simple, but rational, analytical model to simulate the behavior of single piles subjected to lateral loading. The analytical model adopted will be based on the Winkler hypothesis and p-y approach, which is commonly used in engineering applications. In this study, the non- linearity of the soil is simulated by applying nonlinear soil springs, while the nonlinearity of a pile is modeled by placing distributed plastic hinges in beam elements. The distributed plastic hinge model can completely capture the development process of plasticity in piles. Finally, this study proposed the procedures of the fragility analysis for pile-supported wharf case. In modeling a wharf structure, the nonlinearity of the soil and the piles should be considered to account for their effects on the lateral response of the structure. And the proposed fragility analysis procedure can successfully establish the fragility curves of pile-supported wharf structures from illustrative examples.

Pile foundation is a very common way to support the structures built on slopes. When earthquakes strike, they may drive the slopes to move and slide, which would exert additional loading to the piles. In addition, the cyclic loading may weaken the soil surrounding the pile if the induced strain is large. All of these may cause damages to the pile foundation which, in turn, affect the structure supported by the foundation. In the discipline of geotechnical earthquake engineering, the seismic behavior of pile can be analyzed by dynamic p-y method, or dynamic finite element / finite difference analysis. In this research, finite difference analysis (using commercial software FLAC) is utilized to model the behavior of pile installed in sloping areas. Different pile lengths, ratios of bedrock depth to pile lengths and locations of piles would be considered. Moreover, effect of input ground motion variability on pile response is studied. This is achieved by using 30 input ground motions (each with different ground motion characteristics). These ground motions are selected based on the target design spectrum for Taipei Basin, which has 10-percent probability of exceedance in 50 years (corresponding to the return period of 475 years). Pile performance considered in this study includes maximum moment, maximum shear force and maximum lateral displacement. Trends of the pile response with ground motion parameters, model geometry, pile configuration and analysis types are evaluated.

In the present study, a small scale 1-g model test has been developed in the laboratory to study the behaviour of a long flexible single pile embedded in a slope of soft clay with different slope angles and L/D ratios, and subjected to a static lateral loads using loading frame and frictionless pulley arrangements. A steel tank of size 2 m × 1 m × 1 m and an aluminum model pipe pile were used to carry out the experimental studies. The size of steel tank and the model pile were designed to suit the present study. An aluminum instrumented model pile of length 810 mm, 25.46 mm outer diameter and 1 mm thickness was used for the present study. The clay sample which was used in the present study was collected from coastal district Nagappatinam of Tamil Nadu (INDIA). A series of model test has been carried out on a clayey soil of soft consistency (Consistency Index Ic = 0.42).The model aluminum pile was embedded on different slopes (1V:1H, 1V:1.5H, 1V:2H, 1V:3H and 1V:5H) and subjected to static lateral loads. To obtain the long flexible behaviour of model pile, the length (L) to diameter (D) ratio of 20, 25 and 30 was considered and also the relative stiffness factor (R) for clayey soil was kept more than 3.5. The tests were also carried out on a horizontal ground surface for comparison. From the experimental studies, the lateral pile head deflection, bending moments and the lateral deflection behaviour along the depth of pile were studied. And also, the effect of L/D ratios and slopes on lateral deflections and maximum bending moments were studied in detail. In order to include the effect of L/D ratios and slopes on pile capacity and maximum bending moments, an expression was developed by multiple regression analysis and proposed a correction factor. From the bending moments and deflections‘ profile, the p-y curves (soil resistance (p) and lateral deflection (y) along the pile shaft) for a single pile embedded on a crest of soft clay with different slopes and L/D ratios were developed, a case for which no such curves exist so far. The effect of slopes and L/D ratios on p-y curves was also studied. The results from experimental studies reveals that when ground surface changes from horizontal to 1V:1H or 1V:1.5H or 1V:2H or 1V:3H or 1V:5H slopes; the lateral load capacity was reduced significantly for all the length (L) to diameter (D) ratio of 20, 25 and 30. This reduction in pile capacity for sloping ground was due to the reduction in passive resistance of soil in front of the pile. It was also observed that the lateral loads – deflection behavior of 1V:5H slope was almost same as horizontal ground surface for all the L/D ratios. From the bending moment behaviour, it was found that the maximum bending moments increases with increase in applied loads. And also, the increase in L/D ratio changes the behaviour of bending moment behaviour significantly along the depth of the pile. It was observed that as L/D ratio increases, the bending moment decreases. This behavior was due increase in the long flexible behaviour of the model pile. In order to include the effect of L/D ratios and slopes on lateral load capacity of the pile and the maximum bending moments of pile, an expression was developed by multiple regression analysis and a correction factor was proposed considering slope effect on lateral load for calculating the pile capacity for sloping ground surfaces. The variation of depth of fixity due to change in L/D ratios and ground slopes was also studied. From the results, it was observed that the depth at which maximum bending moment occurs (depth of fixity) decreases with increase in the L/D ratios from 20 to 30. It was observed that the depth of fixity occurs almost at a depth of 14.3D, 12.3D and 8.5D (D=diameter of pile) below the pile head for the length (L) to diameter ratio(D) of 20, 25 and 30 respectively. This was due to increase in the relative stiffness of the pile and the soil. It was also observed that the depth of fixity not changes much due to change in ground slopes. A non-dimensional design chart has been produced between dimensionless applied load and dimensionless bending moment which enable to value maximum bending moment promptly for laterally loaded piles in sloping ground with in the given parameters. The applicability of the correction factors and non-dimensional chart are suitable for within the chosen experimental parameters. Also, a new set of p-y curves were also developed for a single pile embedded on crest of soft clay with different the length (L) to diameter(D) ratio (20, 25and 30) and slopes (1V:1H, 1V:1.5H, 1V:2H, 1V:3H and 1V:5H). The effect of slopes on p-y curves for different L/D ratios was also studied. From the results, it was observed that the soil resistance was found to be increasing with increase in soil depth irrespective of slopes. This behavior was observed almost till the depth of fixity. The soil resistance beyond depth of fixity was not significantly changes the behaviour of p-y curves. It was observed that for the length (L) to diameter (D) ratio of 25, beyond the depth of 9.4D (D=diameter of pile) below the soil surface, the behaviour of p-y curves were not significantly changes irrespective of slopes, whereas, for the length (L) to diameter (D) ratio of 30, this depth was found to be 8.4D below the soil surface. Further, a set of non-dimensional p-y curves were also developed for single pile in sloping ground, which enable to obtain the deflection of laterally loaded pile in sloping ground. In addition, the experimental results were validated by numerical analysis using PLAXIS 3D Foundation. The numerical results were compared with that of experimental results and found to be good agreement. The numerical results slightly underestimate the experimental values. For all the cases, the difference between experimental results and numerical values were less than 10%, which is generally an acceptable range. Further, the sensitivity analysis of model was also carried out by changing the soil parameters. Finally, the behaviour of group of piles located on sloping ground surface was also studied by numerical analysis. A field test performed by Rollins et al. (1998) on a 3x3 group of piles was used for numerical study. A 3x3 pile group of piles having 9.1m length was used for the analysis. The soil profile which was used for the present analysis consists of soft to medium-stiff clays and silts underlain by sand. The numerical model was validated and a parametric study was conducted. The group of piles was placed on a crest of slopes (1V:5H and 1V:3H) to study their behaviour due to lateral static loads. The effect of slopes on pile capacity and the behaviour of lateral deflection and bending moments along the length of group piles for different rows were studied.

This project named as “DESIGN OF EARTH-QUAKE RESISTANT MULTI-STORIED RCC BUILDING ON A SLOPING GROUND” involves the analysis of simple 2-D frames of varying floor heights and varying no of bays using a very popular software tool STAAD Pro. Using the analysis results various graphs were drawn between the maximum axial force, maximum shear force, maximum bending moment, maximum tensile force and maximum compressive stress being developed for the frames on plane ground and sloping ground. The graphs used to drawn comparison between the two cases and the detailed study of “SHORT COLOUMN EFFECT” failure was carried up. In addition to that the detailed study of seismology was undertaken and the feasibility of the software tool to be used was also checked. Till date many such projects have been undertaken on this very topic but the analysis were generally done for the static loads i.e. dead load, live load etc, but to this the earthquake analysis or seismic analysis is to be incorporated. To create a technical knowhow, two similar categories of structures were analyzed, first on plane ground and another on a sloping ground. Then the results were compared. At last the a structure would be analyzed and designed on sloping ground for all possible load combinations pertaining to IS 456, IS 1893 and IS 13920 manually.

AbstractThe uncertainty of pile and soil and slope effect are two of the major factors affecting the horizontal bearing capacity of piles of transmission tower in sloping ground. In order to analyze the influence of the two factors on the reliability of pile, this paper proposes a reliability analysis method for horizontal bearing of pile foundation in sloping ground based on proxy model. Firstly, the analytical model of horizontal bearing of the pile foundation in sloping ground was derived, and corresponding performance functions were constructed. Secondly, by combining Kriging model method with the performance functions, the reliability analysis method of pile foundations in sloping ground is established. Finally, taking a typical transmission line project in mountainous area as an example, the horizontal bearing reliability of pile foundation was analyzed. The results show that the proposed analysis method can quickly converge to the horizontal bearing limit state of pile. Slope effect has more significant influence on horizontal deformation than that of material yield. Among the uncertainty parameters, the bearing capacity of pile foundation is sensitive to the dispersion degree of horizontal force, pile diameter and the elastic modulus of foundation pile.

In the concrete era of construction activities, there is scarcity of land especially in metro cities. Even though if there is availability of land it may in the sloping ground, hillocks or on land filled areas, in such areas there will be difficulty in the construction and design aspects. To maintain the slope of the strata, different degrees of such buildings step back towards the slanting slope and may likewise also have set back simultaneously. Hence in the present paper, an attempt has been made to study, G+12 storey building assumed to be in flat ground and also on sloping ground with 20 degree inclination. The model considered to be a soft storey with infill walls and two different shear wall arrangements. The building has been modelled in ETABS software with response spectrum method of analysis. The study reveals that model with shear wall improves the performance of the structure in terms of displacement, drift and time period apart from the fact that the structure being constructed in normal ground or sloping ground.

This paper presents flight test results from a research investigation into the effect of sloping terrain on hover power required. The investigation involved flight test data that were collected for a UH-72A Lakota helicopter while hovering inside ground effect above sloped terrain of varied gradients, in several aircraft orientations and multiple heights above the ground. Performance data were collected over a range of thrust coefficients by varying aircraft weight, rotor speed and environmental conditions over two sorties. The data are compared and contrasted to provide specific insight into the effects of slope magnitude, slope orientation, and rotor hub height. The results demonstrate that hovering over sloping terrain yields performance effects that are both non-intuitive and operationally significant. In particular, the effect of the sloping terrain was seen, in some conditions, to cause power requirements that exceed those for hover out-of-ground-effect, a traditional worst-case value for pre-mission performance planning.

In many places of Kerala state the topography is sloping especially in the districts of Kottayam, Thiruvananthapuram, Kasaragod etc. A sloping ground is in unstable equilibrium, when compared with a level ground. When we construct structures on sloping ground, foundations will be placed on the slope at various levels. Applying loads on a slope of various levels may further degrade its stability and in addition, there will be interference between adjacent footings. Since the foundations are at different levels the stressed zones will overlap which may lead to differential settlement. This paper investigates the load - settlement behavior of footing resting on slopes, by carrying out a series of laboratory scale load tests on model footings resting at various levels along the slope surface. The parameters varied are eccentricity and slope angles. Finite element analyses are carried out with the FE software PLAXIS 2D and the results are compared with those obtained from laboratory scale load tests for validation.
