Design Spectrum-Based Evaluation of Seismic Demand of Tall Buildings

Abstract eng:
Design spectrum-based evaluation of the seismic demand of tall buildings using modified consecutive modal pushover analysis (MCMP) method is presented, whereas paper, only the multi-stage consecutive pushover procedure is adopted and the contribution of different modes and target displacements are obtained from response spectrum analysis using design spectrum. The final response is the maximum value of the responses at the end of each pushover stage. Comparison of the results from the nonlinear response time history analysis (NL-RTHA) method, the modal pushover analysis (MPA) method, the modified consecutive modal pushover analysis (MCMP) method and the proposed design spectrum-based evaluation (DSE) procedure is made. It can be seen that by using the MCMP in the DSE procedure, the evaluation procedure can predict the seismic demand of buildings, such as inter-storey drift ratio and hinge plastic rotation efficiently and accurately. The results are very close to those obtained from the NL-RTHA method. Owing to its simplicity, accuracy and efficiency, the proposed DSE procedure is considered to be a very promising tool for fast prediction of the seismic demand of tall buildings.
