| 摘 要： | 对有初应力的钢管混凝土轴压短柱受力全过程进行了数值分析.结果表明,初应力的存在对钢管与混凝土的相互作用有较大的影响.初应力越大,构件进入弹塑性阶段越早,套箍作用出现得越晚.采用极限平衡法对有初应力的钢管混凝土轴压短柱极限承载力的分析表明,初应力使其极限承载力降低的趋势明显,套箍系数的改变对承载力降低的趋势影响不大.最后...

| Abstract: | The whole process subjected axial load of CFST stub with initial stress is analyzed by numerical method.Analyses results indicate that the presence of initial stress has a significant effect on the hooping effect,initial stress make the elastic-plastic phase appeared ahead and the hooping effect appeared postponable.Adopting the limited equilibrium method,formulations to predict the ultimate load-carrying capacity of CFST stubs with initial stress are presented.Analyses results indicate that the trends of u... |
