starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

post failure analysis of massive structure infers that soil-structure interaction (ssi) is a crucial phenomena influencing seismic response of massive structures. cable-stayed bridge’s popularity and numbers are increasing now-a-days because of economical longer span & aesthetic good look. the current paper examines the effect of depth of foundation on seismic response of cable-stayed bridg...

Abstract Infill Masonry Walls (IMWs) are used in the perimeter of a building to separate inner and outer space. IMWs may affect lateral behavior buildings, while they different from those partition walls that two spaces. This study focused on seismic vulnerability assessment Steel Moment-Resisting Frames (SMRFs) assuming placement incorporating nonlinear Soil-Structure Interaction (SSI). The ai...

An improved Penzien model is proposed in this paper as a simplified of soil–pile–structure interaction. The dynamic nonlinearity soil under earthquake excitation simulated by ANSYS free-field and added to the original model. uses finite element software 2021 simulate soil. then used calculation numerical substructure. A substructure pseudo-dynamic test based on carried out. realization verifies...

A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...
