Optimization and evaluation of three-dimensional high-rise concrete structure equipped by TMD with considering the soil-structure interaction effect

Abstract

During the past two decades, countless and valuable studies have been conducted on passive seismic control of structures on two-dimensional shear frame model and a few on three-dimensional shear frames. To simulate the actual behavior of buildings with higher accuracy, it is necessary to use more realistic and more complex models in evaluating the seismic performance and controller design. In this study, two indicators related to the structural damage and efficiency control have been used for the seismic control of the structure considering the soil-structure interaction (SSI) effect. with a detailed and complex three-dimensional finite element model in the OpenSees software, a twenty-story concrete structure is designed by the performance based plastic design (PBPD) method; the optimization process of control system and structure performance under the circumstances taken into account at the design stage have been studied. Seismic performance subjected to three acceleration records of far-field earthquake has been investigated and to consider the effects of SSI, the simplified cone physical model has been used. Results indicate that according to the type of soil for which the structure is designed, Tuned Mass Damper (TMD) cannot be reliably used to reduce lateral displacement of the structure, but TMD shows a proper performance in reducing inter-story drift.
