Evaluation the Impact of Corruption, Tax Burden, and Income on the Size of the Shadow Economy

Abstract

The present study investigates the behavior of passive control systems or structures using tuned mass dampers (TMD). It also investigates the effect of near fault earthquakes on the performance of control systems. To this end, foureight, and fifteen storey steel moment resisting frame (MRF) buildings were designed three dimensionally with Tuned Mass Dampers and subsequently modeled in a finite element analysis program — OpenSees, and analyzed diachronically. First, Models that use Tuned Mass Dampers and those that do not use them were analyzed. Then base sheer and inter-storey drift were computed in both states. Finally, the effect of the number of stories and the frequency content of near-fault earthquakes on the performance of the structure was investigated.
