抗震结构基于最大弹塑性位移耦合作用的滞回耗能谱
|
摘要
针对抗震结构研究了能够综合考虑结构弹塑性位移耦合作用的滞回耗能谱(简称"VH谱")。通过自编的Matlab程序,进行了大量的单自由度体系非线性时程分析,计算得到了一系列VH谱曲线,并拟合回归了4类场地的VH谱公式及其相关系数。VH谱综合考虑了结构最大弹塑性位移和结构累积滞回耗能的耦合作用,更加合理地反映结构在罕遇地震作用下的弹塑性行为,研究成果可供抗震结构基于能量性能设计或评估使用。
Hysteretic energy spectra(simply called "VH spectra"),considering the coupling effect of maximum elasto-plastic deformation,are studied for aseismic structures.Based on self-compiled Matlab program and lots of nonlinear time history analysis for single DOF system,a set of VH spectra was presented and then according to the regression of the data an expression and coefficients about VH spectra of four types of site were obtained.The coupling effect of maximum elasto-plactic deformation and cumulative hysteretic energy could be considered in VH spectra,thus reasonably reflecting the actual elasto-plastic behavior of structure under the rare earthquake action.The results can be applied to energy-based seismic design or structure evaluation in the future.
