扇形切角构造对钢框架梁柱焊接节点抗震性能影响的研究
|
摘要
基于震害分析,以扇形切角为主要参数,对4个足尺钢框架梁柱焊接节点进行往复加载下的破坏试验。通过对弯矩-塑性转角和弯矩-累积塑性变形倍率曲线对比表明,扇形切角构造和引弧板是节点塑性变形能力和破坏形式的主要影响因素。改进扇形切角构造是一种有效措施,既可提高节点的抗震性能,又能保持制作工艺与传统节点基本相同。
Based on the analyses of earthquake failure,the failure experiment on four full-size specimens of steel frame beam-column welding connections under cyclic loading is accomplished,taking account of influencing factor in form of scallop structure.According to a comparison of moment-plastic corner cure with moment-cumulative plastic deformation multiple cure,the test results show that scallop structure and steel tab are the primary factors influencing the plastic deformation capacity and failure mode of beam-column connections.Improving the scallop structure is an effective means,which can improve not only the aseismic behavior but also the construction technique is the same as the traditional connections.
