Since the occurrence of the Cairo earthquake on October 1992, the design of structures for earthquakes became a
major demand enforced in the Egyptian design codes. The seismic response of building structures can be
estimated through utilization of a variety of analysis methods that range from simple equivalent static analysis to
complex nonlinear dynamic analysis. The traditional approach is to employ equivalent static analysis methods, while
current design practice is moving toward an increased emphasis on the nonlinear analysis method. The Egyptian
code provisions for building seismic design adopt the traditional approach of equivalent static load method as the
main method for evaluating seismic actions and recommend the response spectrum method for nonsymmetrical
buildings. This study aims to evaluate the Egyptian code provisions for the seismic design of moment-resistant
frame multi-story building through using nonlinear time history analysis. The analysis procedures are evaluated for
their ability to predict deformation demands in terms of inter-story drifts, potential failure mechanisms and story
shear force demands. The results of the analysis of the different approaches are used to evaluate the advantages,
limitations, and ease of application of each approach for seismic analysis.
