【摘要】 结合工程实践,进行了三个不同形式的后包钢管混凝土框架节点和一个普通钢管混凝土框架节点的低周反复加载试验。研究后包钢管混凝土框架节点承载能力和抗震性能,以及不同钢管厚度、不同加劲肋形式对节点承载能力和抗震性能的影响。试验结果表明,后包钢管混凝土框架节点的抗震性能不低于普通的钢管混凝土框架节点。研究为加固钢筋混凝土柱提出了一种新方法。更多还原

【Abstract】 Tests for three different kinds of steel beam-RC column post-covered with steel tube frame joints and one concrete filled steel tube frame joint are carried out,and the effect of tube width and the stiffening rib on the behavior of bearing capacity and seismic performance have been studied.The test results show that the bearing capacity and performance of steel beam-RC column covered steel tube joints is not lower than that of the common concrete filled steel tube frame joint.更多还原
