| Abstract | ||
| One of the most important factors affecting the design of the structures is the impact of the earthquake loadings on the forces and the design displacements. Nevertheless, the influences of the near structures from the existing channels, that sometimes can cause great changes in forces and displacements, can never be neglected. Therefore, the induced displacement due to the adjacent channels of constructed buildings foundations has been investigated in this study. Having the results of the study, it can be evaluated, whether the amounts of variations in forces and displacements are in the allowable ranges, and what measures and precautions are needed to save the structures in case of having excess changes in these parameters. In this paper, the site characteristics of buildings foundations are first investigated. Then the excavation of the building is modeled, while the adjacent channels are taken into account. Finally, the impact of the excavation on the adjacent structures under earthquake loadings is studied and investigated. The accelerograph of El Centro earthquake has been used for seismic analyses and fifteen stories buildings have been modeled as well as the adjacent channels. | ||
