摘要

采用OpenSees建立基于纤维截面的空心钢管混凝土柱有限元模型

对空心钢管混凝土柱的滞回性能进行计算。在该有限元模型基础上

考虑轴压比、长细比、截面空心率、截面含钢率、混凝土强度和钢材强度等因数对骨架曲线恢复力模型的影响

结合正交试验设计方法

对骨架曲线恢复力计算公式进行回归分析。研究结果表明:1数值计算结果与试验结果吻合良好;2得到的空心钢管混凝土柱骨架曲线恢复力计算公式在一定设计参数范围内具有较高的计算精度。

Abstract

The software OpenSees was adopted in this paper to build finite element models for hollow concrete filled steel tubular（ H-CFST）. The influence of several factors

such as axial compression ratio

slenderness ratio

hollow ratio

steel ratio

concrete strength and steel strength

on resilience model of skeleton curve was discussed. Then

the resilience formula was regressively analyzed using the combination orthogonal design method. The results indicate that 1) the numerical calculation conclusions well fit the test and 2) the resilience formula for H-CFST is possessed of reliable precision in certain range of design parameters.
