Modeling the soil–structure interaction (SSI) in seismic design involves use of soil response curves for single-degree-of-freedom (SDOF) structures; however, real structures have multiple degrees freedom (MDOF). In this study, shaking-table-derived p-y SDOF and MDOF superstructures were compared using numerical analysis. It was found that an structure experienced less displacement than same wei...

Considering soil layering is a crucial and effective issue in investigating the seismicity of structures. However, previous studies have not examined presence rock layer soft soil. So, present paper, effect on forces displacements created low-and mid-rise steel moment frame was investigated. Thus, several numerical calculations were performed 12 different sizes layers at three depths. Finite el...

There are various methods for the analysis of the interactional behavior of the surrounding land, using the lining structure which is the most common method of deigning lining structure tools for the static loads by using the hyper static methods. In recent years, there has been a question that depicts whether this method provides the best results in designing the tunnel structure or not.Due to...

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...

This paper describes comparative experiment on corrugated steel pipe culverts with different stiffness. The two culverts both with 1.2m span and 4m backfill height but with different corrugation pattern and plate thickness were constructed side by side. Displacement, strain and soil pressure at critical points were tested during construction. Two-dimensional (2D) finite element (FE) models were...

This paper reports the results of an experimental study conducted to demonstrate the feasibility and capability of magneto-rheological (MR) dampers commanded by a decentralized control algorithm for seismic control of nonlinear civil structures considering soil-structure interaction (SSI). A two-story reinforced concrete (RC) frame resting in a laminar soil container is employed as the test spe...
