摘要
为研究圆端形钢管混凝土构件弱轴抗弯性能,利用有限元分析软件ABAQUS对其进行模拟,对其破坏模式、受弯全过程进行了分析,并基于大量的参数分析结果,提出了圆端形钢管混凝土弱轴受弯构件抗弯承载力计算公式。研究结果表明:圆端形钢管混凝土弱轴受弯构件抗弯承载力随钢管壁厚、钢材强度、高宽比的增加而提高,而混凝土强度的改变对其抗弯性能的影响较小。
In order to study the mechanical behaviours of the concrete-filled round end steel tubular weak-axis flexural members,the finite element analysis software ABAQUS was used to simulate the failure mode and the whole bending process.Based on the analysis results of a large number of parameters,a formula for calculating the flexural strength of concrete-filled round end steel tubular weak-axis flexural members was proposed.The results showed that the flexural capacity of concrete-filled round end steel tubular weak-axis flexural members increased with the increase of wall thickness,steel strength and aspect ratio,while the change of concrete strength had less influence on the flexural performance.
