Abstract

Abstract

The natural periods and corresponding modes of structure are obtained by free vibration analysis.Based on the periods,the equivalent displacement of single-degree-of-freedom system for each mode is deduced by displacement response spectra,and the structural lateral elastic displacement of each mode could be determined by equivalence principle.So the structural lateral elastic displacement can be obtained by SRSS rule.Then,based on the story drift ratio limits,the structural target lateral displacement of each mode could be determined,and the shear in each story is obtained by SRSS rule too,the direct displacement-based seismic design(DDBSD) method of high-rise buildings considering higher mode effects is realized.The paper illustrates the application of the proposed procedure with an example and attempts to prove its feasibility by elasto-plastic time-history analysis.It provides a valuable thought for DDBSD method of high-rise buildings.
