摘　　要：简要介绍本次JGJ 149-2006《混凝土异形柱结构技术规程》(以下简称《规程》)修订中轴压比限值修订需要考虑的内容,以及钢筋混凝土异形柱延性计算程序的原理,计算值与实验结果吻合较好;进而对不同计算参数进行了延性分析,回归得到相应的轴压比限值;最后在此研究的基础上,提出与异形柱结构延性的几个相关问题,供《规程》修订后续工作加以探讨。Briefly recommending required content of the limitation value of axis compression ratio for revising Technical specification for concrete structures with specially shaped column(JGJ 149-2006)(hereinafter named the code) and principle of complete response process for ductility of RC columns in this article,and the calculated results of curvatural ductility factor of specially shaped columns accord with the tested results well,then ductility of many relevant factors were analyzed.On the base of regression analysis for the ductility,the limitation value of axis compression ratio is attained,finally based on that,several relevant questions of ductility for concrete structures with specially shaped column are mentioned and discussed henceforth for revising the code.
