Incremental Dynamic Analysis (IDA) of Equipped Constructs to Fluid Viscous Dampers and Investigating Responses

Hamidreza Ashrafi, Soroush Dadgar, Peyman Beiranvand

Abstract


The goal of this research is an utter assessment of steel moment frames equipped with linear and nonlinear fluid viscous damper performance. To achieve this, dampers with powers of smaller attenuation, equal or larger than one have been used. The system has investigated a structure which is obtained from moment frames and fluid viscose damper combination through using incremental dynamic analysis (IDA)and relative movement parameters, the maximum base shear and change the location of construction waste have been obtained through inserting dampers and different percentages of attenuation and have been compared with each other. In order to this, 6 different records of earth quick related to near field have been used and at the end of analyses, a complete image of structure behavior has been drawn by IDA curves in PERFORM-3D software.

Keywords
