摘要: 通过三个外包钢混凝土框架边节点的试验,以柱轴压比、梁角钢布置形式、配钢率等为主要研究参数,研究现浇外包钢混凝土框架边节点在高轴压比条件下,节点的抗震性能和角钢受力特点。在分析的基础上,给出了此类边节点抗剪承载力计算公式。Abstract: Three specimens of warpped steel concrete exterior joints which varied in axial compression ratio and the form of angle steel for beam, are put to test;and the forced feature of the angle steel as well as the aseismic behavior of the joints under the high axial compression ratio are studied.Based on the analyses, formula of shear carrying capacity is given.
