Abstract:

Strong earthquakes induce high amount of energy to the affected structures. If this energy can be controlled and dissipated in a manner independent of the structural components, the seismic performance and response of the structure will be substantially improved. This objective can be achieved by using passive control of the structures such as Tadas damper or base isolation techniques. This study presents the analysis of building structures equipped with TADAS system and subjected to strong earthquake excitation. In this study, the effect of the using of Tadas Damper for improving the seismic performance of an existing 9- story steel structure in Iran has been investigated by nonlinear dynamic analyses. The analysis was carried out by considering several nonlinear dynamic analysis . In nonlinear dynamic analyses, the response of the structure to seven scaled earthquake records matched to the design spectrum has been obtained. Initially, static analysis of the structure has been performed and the results such as stress state are stored as initial condition then structure was analyzed under earthquake vibration. In order to demonstrate the effect of TADAS damper system in the structures, an attempt has been made to compare its structural response in terms of story drift and base shear , displacement and dissipated energy in the structural members with and without TADAS damper. It was observed that structure equipped with TADAS damper system, have the potential to improve the seismic behavior of full-scale civil structures
