Abstract:
The main aim of the proposed research is to provide guidelines for critical structure height above which Response Spectrum Analysis (RSA) significantly affects the structure design. Response spectrum analysis of 20 story building has been discussed in detail and comparison of static and dynamic analysis and design results of buildings up to 400 ft height (40story) in terms of percentage decrease in bending moments and shear force of beams, bending moments of columns, top story deflection and support reaction are presented in this paper. Percentage decrease in reinforcement area requirement for different members has also been discussed.
