Location of semi-rigid connections effect on the seismic performance of steel frame structures

In design steel frames, combining semi-rigid and rigid connections can result in better structural performance, particularly seismic locations. this study, the effects of beam-to-column located on performance frame structures are investigated. The analysis uses six twelve-story moment resisting frames (MRSF) with rigid, semi-rigid, dual beam-column connections. These designed according to Egyptian codes. Drain-2Dx computer program seven earthquake ground motions used non-linear dynamic analysis. rotational stiffness is indicated through end fixity factors a value equal 0.6. performances these evaluated roof drift ratio (RDR), maximum story ratios (SDR), column axial compression force (MACF). results that quantities fundamental periods, ratio, related stiffness, rigidity, number frames.
