This book is intended to introduce computer aided comparative analysis of different types of Moment Resisting Frames such as Special Moment Resisting Frame, Ordinary moment resisting frame, Dual Moment Resisting Frame and Intermediate Moment Resisting Frame by considering actual existing high rise building. The computer modeling of the building is done by ETABs (Extended Three dimensional Analysis of Building Systems) and the foundation analysis is done on SAFE. The modeling procedure of the softwares and structural analysis concepts are comprehensively explained in this book. In this book ACI code is used for gravity analysis and UBC-97 is used for seismic load analysis. The various moment resisting frame models of the building are compared in story drift, story shear, beam reinforcement and column reinforcement. From analysis it is found that the Special Moment Resisting Frame has inherent high over strength and ductility than Intermediate and Dual Moment Resisting Frame that's why the Special Moment Resisting Frame has ultimately less base shear than Moment Resisting Frame which ultimately causes less story drift and story shear.
