Abstract
Moment-resisting frames and braced frames are both currently used as lateral force-resisting systems in multi-storey buildings. A parametric study is presented where 4-bay and 5-bay buildings of different heights (10, 15 and 20 storeys) and different shear link length (1.0m, 1.5m and 2.5m) for regular and irregular configuration are designed as dual systems according to the 2Egyptian Code of Practice for Steel Construction and Bridges3 and 2Egyptian Code for Loads3 (ECP-205 and ECP-201) using the moment resisting frames system and eccentric bracings.The performance of the frames under seismic loading is studied and observed to verify the Reduction factor2R3 proposed by the Egyptian Code (ECP-201).A comparison between the computed values of the reduction factor was performed and it is concluded that a significant effect of the previously mentioned parameters on the seismic reduction factor that need to be considered
