English Abstract
Moment resisting steel frames (MRSF); which are widely used as lateral load Resisting systems for low- to medium-rise buildings; are one of the simplest ductile systems that can be built without bracing elements.
The objective of this study is to evaluate the seismic behavior of a 6-story MRSF designed according to the Egyptian code using the DRAIN-2DX program and Siesmostruct program The 6-story office building is considered to have moment resisting steel frames (MRSF) in the perimeter of the short direction and braced steel frames in the perimeter of the long direction to carry the seismic loads.
The focus of this study is to evaluate the seismic performances of the building MRSF using the two computer programs SeismoStruct and DRAIN-2DX.
Seismic evaluation in this study has been carried out by static pushover analysis and time history earthquake analysis for nonlinear static analysis of building structures.
The columns and beams are modeled using the inelastic force-based frame element type – FB.
An inverted triangular lateral force distribution applied to the structural model in each step of the analysis.
The evaluation is also performed by analyzing the building using nonlinear dynamic analysis.
Ten earthquake records are used in the analysis to cover a wide range of ground motion duration and frequency content the element mass is assumed to be lumped at the joints and viscous damping is assumed 5%.
The mean plus one standard deviation values of the roof-drift ratio, the maximum story drift ratio for the seismic performance evaluations.
The results indicates that the performances under pushover static loading and nonlinear dynamic analysis indicated the same results in two programs.
