Abstract

In this paper, most in uential parameters on nonlinear response of structure-soil-structure system, including time period of main (T1) and adjacent (T2) structure, distance between structures (d) and soil type, have been thoroughly investigated. The purpose of this paper is to understand the e ect of changing each parameter on the nonlinear de ection of structures, investigating the requirements of code and predicting structural behaviour without modelling the adjacent structure. For this aim, six structures of 2 to 15 stories based on two clay samples is modelled with zero, 10 and 25 meters distance and is analyzed using nonlinear time history analysis. direct method is used for modelling the systems. According to the results, soft base is caused sharp increase in the ratio of the rst story drift to the xbase with a minimum ratio of 1. 1 and a maximum of 3. 61. The increase of T1 and T2 is led to increase structural deformation so that T1 e ects are at least twice T2. For main structures with T1 in the range of 0. 7 to 1. 5 times the soil period, Structural drift is intensi- ed; but for main structural time period T1 less than 0. 7 times the soil period, the e ects of structure-soilstructure interaction are negligible. Base on this study, Contrary to the expectation that increasing the distance between structures leads to a reduction in the e ects of Structural-soil-structure interaction, only for structures with time period more than 3 seconds, increase the distance between structures, is decreased adjacent structures e ects. By comparing drift ratio of structure-soilstructure and soil-structure systems, in one third of the upper elevation of the structure, this ratio has a sudden drop that is compensated in the roof, which with decreasing T2 and increasing d, the accumulation of the drift ratio from the roof to the rst oor is transferred. Ultimately, what codes are considered for soft support enforcement is unreliable. Finally, by identifying the key parameters of Structural-soil-structure interaction, relationships are developed to improve the requirements of the regulations for soft support.
