| 摘 要： | 进行了11根圆形和正方形截面的空心钢管混凝土轴心受压长柱试验,研究了空心率、长细比和截面形式对空心钢管混凝土长柱承载力性能的影响,并对空心钢管混凝土轴压长柱的破坏形态进行了分析。分析结果表明,空心钢管混凝土长柱的破坏形态接近于空钢管长柱。同时在前人所做的轴压长柱试验数据基础上,进行了《薄壁离心钢管混凝土结构技术规程》(DL/T 5030-1996)与给出的空心钢管混凝土轴压长柱承载力计算公式的对比,表明给出的公式与试验结果吻合较好,说明使用该公式计算轴压长柱承载力是可行的。

| Abstract: | It has been done that axial compressive experiments on 11 long hollow concrete-filled steel tube(H-CFST) specimens,and analysed the influence of hollow ratio,slenderness ratio and sectional form on bearing capacity of long H-CFST,studied the deformed states of specimens.The results show that the deformed states of long H-CFST specimens are similar to those of steel tubes.The experimental data on other researchers are collected and the formula put forward by the authors is compared with the formula of Technical Code on the Centrifugal Concrete Filled Thin-Wall Steel Tubular Structures,and the results are acceptable. |
