Optimal Retrofitting of the Steel Moment Resisting Frames Using Telescopic Dampers, M.Sc. Thesis Sharif University of Technology ; Mofid, Masoud (Supervisor) ; Eskandari, Morteza (Co-Supervisor)
Abstract
The purpose of this thesis is the optimal retrofitting of the moment resisting frames with telescopic dampers, using the adaptive approach. In this regard, numerical modeling of the telescopic behavior has been presented firstly. Also, a 3,9,20 story (sac) moment resisting frame has been modeled in the OpenSees environment and the time history analysis has been carried out under a specific earthquake record. It is shown that inter-story drifts of the frame exceed the acceptance criteria which has been assumed 2.5% according to the Life Safety limit. Then, the optimal retrofitting of the frame has been done. It is demonstrated that the maximum inter-story drift of all stories is 2.5% or less,...
