| Sumario: | In the last few decades, the idea of using thin steel plate shear wall, ( SPSW ) , has been noted as a lateral load resisting system in design and retrofit of buildings. In this research, it has been tried to determine, the appropriate response modification coefficient ( R ) , overstrength factor and the deflection amplification factor In the reinforced concrete Special moment frames, RC-SMF, with thin steel plate shear wall and using performance-based plastic design, PBPD. To do it, buildings with thin steel plate shear wall system and different story numbers are considered. Static pushover analysis are performed using strip model and OpenSees software. The simulation results were compared with experimental results and acceptable matching was observed. Finally response modification coefficient, overstrength factor and deflection amplification factor for reinforced concrete Special moment frames with thin steel plate shear wall system are calculated based on Uang's method and values of 9.37, 2.21 and 11.06, respectively, has been suggested for ultimate limit state design method. Also, the use of a thin steel plate shear wall in a RC-SMF shows an increase in strength, ductility, elastic hardness and, finally, an increase in the response modification coefficient ( R ) of the structure. |
