ABSTRACT: A prismatic beam made of a behaviorally nonlinear material situated on nonlinear elastic foundation is analyzed under a moving harmonic load moving with a known velocity. The vibration equation of motion    is derived using Hamilton principle and Euler Lagrange equation. The amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam can be calculat...

The aim of this paper is to study the effects of Soil-Structure Interaction (SSI) on the seismic response of coupled wall-frame structures on pile foundations considering the non-linear behaviour of the superstructure. According to the substructure method, the kinematic interaction analysis is performed by means of a numerical procedure obtaining the dynamic impedance functions and the foundati...

Abstract— Though the structures are supported on soil, most of the designers do not consider the soil structure interaction and its subsequent effect on structure during an earthquake. Different soil properties can affect seismic waves as they pass through a soil layer. When a structure is subjected to an earthquake excitation, it interacts the foundation and soil, and thus changes the motion o...

Soakaway disposal wells are used heavily in Sudan for on-site sanitation systems. These have a diameter of 1.5–2.0 m, depth ranging from 10 to 35 and postinstalled brick walls. They often located close building foundation seldom excavated between footings. Although engineers aware induced ground movements, the influence such movements on existing structures currently is ignored both during new ...

In this study, shaking table tests are performed to investigate the behavior of excess pore water pressure in different soft soil-foundations of soil-structure interaction (SSI) system. The variation of the behaviors under cycled minor shock is observed. Moreover, The generation and variation mechanism of excess pore water pressure under earthquake excitation in different soft soilfoundations a...

In common engineering practice, foundation–soil–foundation interaction of shallow foundations is frequently ignored. This presumably for cost/benefit reasons, since computationally demanding finite-element and/or boundary element models are required that purpose, and its effects usually assumed to be negligible. this sense, the present paper provides a simple inexpensive way incorporating throu...

Abstract In this essay, the progressive collapse resistance of reinforced concrete wall-frame structures was evaluated with and without considering soil–structure interaction. The vulnerability frames against investigated middle column removal scenario from first story, based on sensitivity index. To evaluate effects interaction, along soil (hard soil) foundation were simultaneously modeled in ...

Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...
