摘要
为了解钢管混凝土支架构件的工作性能,进行了室内模型试验研究。结果表明,钢管混凝土支架具有较好的弹塑性性能和较高的承载能力。通过介绍试验情况,分析了模型支架构件受力全过程的性能。试验结果对钢管混凝土支架的设计与工程实践具有一定的指导意义和参考价值。
In order to understand the working performance of the concrete-filled steel tubular (CFST) supports. A model experiment study is carried out in this paper. It is found that CFST support has good elastic-plastic behavior and high bearing capacity. The mechanic behavior of CFST supports under load is studied in this paper as well. Conclusions drawn from test results and research have guiding significance and reference value on the design and engineering practice of the concrete-filled steel tube supports.
