Assessing the Effect of Changing the Position of TMD Dampers in Response to Nonlinear Dynamic of Steel Structures

Abstract

In this study, the mass damper designed by nonlinear dynamic analysis was evaluated so that its response met procedural requirements. At this stage structure response can be optimized by changing various vibratory parameters of added mass such as hardness, mass, and also its damping. It was attempted to evaluate the first approximation achieved by nonlinear dynamic analysis of retrofited structures in the RUAUMOKO software. Accordingly, various nonlinear dynamical analysises were done by changing of the hardness values (k) and damping coefficient (C) of TMD damper and at each parameter RPI was used to control structure behavior
