Many researches have focused on the optimal design of tuned mass damper (TMD) system without the effect of soil–structure interaction (SSI), so that ignoring the effect of SSI may lead to an undesirable and unrealistic design of TMD. Furthermore, many optimization criteria have been proposed for the optinal design of the TMD system. Hence, the main aim of this study is to compare different opti...

This paper aims to obtain the optimal distance between the adjacent structures using Particle Swarm Optimization (PSO) algorithm considering structure-soil-structure systems; The optimization algorithm has been prepared in MATLAB software and connected into OpenSees software (where the structure-soil-structure system has been analyzed by the direct approach). To this end, a series of adjacent s...

the seismic analysis of structures in the past relied on the assumed soil desirable effects as the elongation of excitation period with higher damping. therefore, imposing earthquake loading at the foundation level fulfilling higher safety requirements was the common practice until occasional movement amplifications demanded more rigorous research. the goal of the current study is to scrutinize...

Centrifuge modeling has been considered as an effective means of studying flexural soil–pile interaction, yet the conventional use elastic material to model RC pile prototype is unable reproduce important nonlinear quasi-brittle behavior. It also remains a challenge numerically interaction due nonlinearity both soil and materials. This paper presents small-scale for testing soil–structure under...

Several attempts have been carried out to understand the foundation failures during earthquake type of transient loading and it has been found that the interaction effect between soil and foundation is one of the important aspects need to be considered in the analysis and design. In this regard a literature survey has been carried out on frame structures supported on pile foundation which is in...

This study focuses on the shape optimization of concrete gravity dams considering dam–water–foundation interaction and nonlinear effects subject to earthquake. The concrete gravity dam is considered as a two–dimensional structure involving the geometry and material nonlinearity effects. For the description of the nonlinear behavior of concrete material under earthquake loads, the Drucker–Prager...

in this study, a simulation of tire–soil interaction model was considered with special view to two-dimensional (2-d) fem model of carcass. coefficients of mechanical behavior of silty-loam soil were accurately measured to obtain an effective simulation. the results of simulation which was implemented in matlab7, showed that the radial-ply tire had greater tractive efficiency than bias tire at t...
