摘要
通过对1 2根钢管混凝土轴压短柱承载力的试验,研究了该种构件承载力的组成及钢管对混凝土的约束效应,分析了各阶段构件的承载能力,认为:钢管混凝土柱的计算可分为使用阶段和极限承载阶段,并提出了相应的推荐公式,理论计算与试验结果吻合较好。
Through the experiment of 12 CFST column,the composing of carrying capacity and restriction of steel tube were discussed and the carrying capacity was analyzed.It can be concluded that the force process of CFST column was made up of phases-normal phase and limit capability phase.Based on the coincidence of theoretical calculation and experiment,the corresponding commend formula was proposed,which may guide the engineering design.
