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.
