摘要

摘要: 以空心率为变化参数,对5个纯弯构件进行试验研究,同时考察圆中空夹层钢管混凝土在纯弯状态下的力学性能。在确定了钢材和混凝土应力-应变关系模型的基础上,利用数值方法对圆中空夹层钢管混凝土纯弯构件进行分析,分析结果和试验结果吻合较好。最后在参数分析的基础上,提出构件抗弯承载力的简化计算公式。

Abstract: A total of five specimens were tested under pure bending to investigate the behavior of concrete filled double-skin steel tubular(CFDST) beams.The specimens were fabricated with circular hollow section(CHS) as outer and inner skins.The parameters varied in the tests were hollow section ratio.Utilizing the stress-strain relations of steel and concrete presented in concrete filled circular steel tubes,a numerical method is used for the analysis of load-deformation curves of the double-skin composite members subjected to pure bending.The calculated results agree well with those of tests.A simplified model is also developed for calculating the bearing capacities of the CFDST beams.
