| 摘 要： | 进行了钢管混凝土构件的约束扭转试验以及空钢管和素混凝土构件的抗扭对比试验.试验结果表明,在钢管混凝土构件的约束扭转受力过程中,钢管与核心混凝土能够协调变形,表现出良好的约束效应和弹塑性形变规律.钢管混凝土的约束抗扭承载力大于相应尺寸的空钢管和素混凝土抗扭承载力的代数和,为计算其约束抗扭承载力提供了依据.

| Abstract: | The experimentation study for restricted CFST members under torsional loads was carried.Through contrasted analysis among CFST in restricted torsional condition,hollow steel tube and plain concrete,the torsional mechanism of them was studied.The test results show that the steel tube and the core concrete could deform harmoniously.It takes on good restricted effection and elastoplastic properties.From the experiment results,the restricted torsional carrying capacity of CFST is greatly more than the algebraic sum of the hollow steel tube and plain concrete.The foundation of restricted torsional carrying captivity calculation was provided. |
