摘要:
针对钢管混凝土短柱轴心受压过程中钢管与核心混凝土在极限承载阶段时的多向应力状态,引入钢管纵向容许应力折减系数与混凝土抗压强度提高系数,对钢管混凝土的应力状态、轴压承载力计算进行理论分析,给出各系数的计算方法,并将计算值与试验值进行对比。结果表明:该方法计算值与试验值较为吻合;钢管纵向容许应力折减系数的引入有助于加深对钢与混凝土二者之间相互作用的认识,在工程常用范围内可为钢管混凝土结构节点设计提供参考。
Abstract:
According to multiaxial stress state of steel tube and concrete under ultimate state in concrete-filled steel tubular (CFST)stub columns under axial load, longitudinal allowable stress reduction factor of steel tube and compressive strength improvement factor of concrete were defined to analyze the stress state and calculate the axial bearing capacity, and the calculation methods of the factors were proposed. Comparison between the calculation values of the method and test values was carried out. The results show that the calculation results are in good agreement with the test results. The proposed longitudinal allowable stress reduction factor contributes to understanding interaction mechanism and can provide references for joint design of CFST structure in scope of engineering.
