TL;DR: In this article, an L-shape 11 storey building supported by a pile foundation with homogeneous local soil condition is analyzed for dynamic loading including the SSI effect and the significance of the effect has been studied by comparing the responses of the system for fixed base and flexible base condition.
Abstract: All of the civil engineering structures involve some type of structural element which is in direct contact with soil. To estimate the accurate response of the superstructure it is necessary to consider the response of the soil supporting structure, and is well explained in the soil structure interaction analysis. Many attempts have been made to model the SSI problem numerically; however the soil nonlinearity, foundation interfaces and boundary conditions make the problem more complex and computationally costlier. To overcome this problem the attempt has been made to optimize the computational efficiency by applying the equivalent pier method for the deep foundation system. In this research paper the L-shape 11 storey building supported by a pile foundation with homogeneous local soil condition is analyzed for dynamic loading including the SSI effect. The significance of the SSI effect has been studied by comparing the responses of the system for fixed base and flexible base condition. A new approach has been proposed to provide simplicity in SSI modeling and reduce the computational cost (both memory and time wise). The approach includes the applicability of the equivalent pier method for the asymmetrical pile groups system, including SSI effect of the pile foundation system. The approach is validated for group effect and found that equivalent pile method can successfully be adopted and helps to reduce the computational cost of SSI problem. To understand the applicability of EPM approach, the parametric study has been carried out for different input of earthquakes and soil types. In accordance with this the three distinct earthquakes, including 1995 Chamba (M = 4.9), 1999 Uttarkashi (M = 6.9) and 2001 Bhuj (M = 7.7) and soil types including cohesive, cohesionless and C-Phi soils have been considered for SSI analysis. The study observed that, earthquake magnitude and soil type shows the major impact on the response of the SSI system.

TL;DR: In this paper, the authors investigated the amount of arching in a rigid horizontal support buried under a soil cover of finite depth, where the surface of the soil is subjected to high overpressure.
Abstract: When one part of the support of the soil settles relative to the other parts of the support, the pressure on the deflecting support reduces with a corresponding increase of pressure on the neighboring parts. This transfer of pressure from the deflecting part to the neighboring soil is known as the arching effect. In the present study, the amount of arching, that is, the amount of pressure transferred to the neighboring soil when a rigid horizontal support buried under a soil cover of finite depth deflects, is investigated. The surface of the soil is subjected to to high overpressure. The soil is assumed ideal characterized by modulus of elasticity E, and Poisson's ratio, Mu. Solutions based on the equations of plane strain are obtained in the form of infinite series. Since soil cannot be expected to be effective in tension, a condition is imposed that the net pressure on the deflecting base cannot be tensile. It is shown that arching in this case is a function of the parameters b/h, ph/dE, and Mu, where 2b is the width of this base, h is the depth of soil, p is the pressure on the base with no displacement and d is the amount of base displacement. The first six terms of the infinite series solution are evaluated using a digital computer for a wide range of parameters. Graphs are presented showing the pressure distribution on the base, and the amount of arching over the base. An example is given to demonstrate the use of these plots. /Author/

TL;DR: In this paper, the AASHTO method for calculating the load on buried pipe is evaluated against the elastic solutions of Burns and Richard to derive expressions for the vertical soil arching factor for buried pipe.
Abstract: Soil arching associated with buried thermoplastic pipe is discussed. First, the soil arching phenomenon is described. Then two different approaches are mentioned from the literature to represent the degree of soil arching (or vertical arching factor). The elastic solutions of Burns and Richard are revisited to derive expressions for the vertical soil arching factor for buried pipe. Comparison of the elastic solutions and field soil pressure cell readings reveals the importance of incorporating a bending stiffness parameter. With this finding, the AASHTO method for calculating the load on buried pipe is evaluated against the elastic solutions. The analysis reveals that the AASHTO method is conservative, overestimating the load on thermoplastic pipe by up to 30%. Further evidence to support the finding is found within the strain gauge readings taken on the pipe walls in the field. Therefore, alternative equations derived directly from the elastic solutions are recommended to predict the load on buried therm...
