本文主要介绍二十二组钢梁与箱型柱抗弯接头试体的耐震行为与破坏模式,其中十七组试体采用梁翼切削(reduced beam section,RBS)式接头,另五组以梁翼加盖板的补强(enlarged beam section,EBS)式接头,所有试体均为梁腹栓接、梁翼焊接(BWWF)的现场施作接头。试验结果显示,七组梁翼切削试体及三组梁翼加盖板试体具有4%弧度层间位移角或3%塑性转角以上的变形能力,此十组试体的平均梁塑铰应变硬化系数为1.22。由试体破坏形式归纳,造成梁柱接头变形能力不足的破坏模式包括 ...

为研究FRP管-橡胶混凝土-钢管组合柱(RC-DSTCs)的轴压性能,进行了7根长柱试件的轴压试验。观察RC-DSTCs在轴压状态下的破坏模式,通过荷载-位移曲线、荷载-应变曲线和环向-轴向应变曲线分析长细比、空心率对RC-DSTCs轴压性能的影响,并提出了RC-DSTCs的轴压理论承载力计算公式。结果表明:随着长细比的提高,RC-DSTCs的轴压破坏模式由材料破坏向弯曲失稳破坏转化,但所有RC-DSTCs的钢管均达到屈服应变0.2%;同时,随着长细比的提高,RC-DSTCs的峰值荷载 ...
