中国与新西兰规范中混凝土结构弹性位移角限值及有关影响因素分析

按照中国规范与新西兰规范建立钢筋混凝土框架模型，比较两国规范在正常使用极限状态下弹性位移角限值的宽严程度。就中国规范算例，按照新西兰规范逐个改变设计地震作用、构件有效刚度、隔墙影响和偶然偏心率等因素，分析各因素对结构弹性位移角的影响程度，从而对比两国规范的弹性设计地震作用水平差异。

Analysis of the elastic inter-storey drift limit and correlative influence factors in China and New Zealand

Several models of reinforced concrete (RC) frame were built based on Chinese and New Zealand codes to compare the strictness extent of the elastic inter-storey drift limits in service ability limit state between the two countries. Initial Chinese code models were partially substituted by the seismic design load, effective stiffness of elements, in-filled wall factor and eccentricity complied with New Zealand code, respectively, for analysis of the influence of these factors on the elastic inter-storey drift. Accordingly the elastic design seismic actions between China and New Zealand have been compared.
