钢筋砼不等肢T形柱延性的计算分析

Calculating Analysis of Ductility of R.C.Inequiaxial T-Shaped Columns

采用全过程非线性分析方法,编制了不等肢异形柱延性性能非线性分析程序(SCDP),程序分析结果与试验结果的对比表明,二者吻合较好.应用该程序对243根不等肢T形柱进行了计算分析,研究了荷载角、轴压比、箍筋间距、截面肢长等因素对不等肢T形异形柱截面延性性能的影响,得到了其延性变化规律.

A computer program（SCDP） for analysis of the ductility of the special - shaped columns is compiled in this paper with the method of the full - range nonlinear analysis. Comparison of theoretical results calculated by the SCDP program and experimental results confirms the correctness and applicability of the software. 243 sets of inequiaxial T- shaped columns are calculated, and many relevant factors such as angles of loading, axial force ratio, spacing of lateral reinforcement and change of section for the ductility of the inequiaxial T- shaped columns are analyzed.
