摘要
结合已有研究成果及国外规范的建议,对应用于多层钢框架中的半刚性端板连接梁柱节点提出了标准构造建议,并针对此类端板连接提出了相应的弯矩—转角(M-φ)曲线形式及简化计算方法。通过将计算结果与相关试验结果对比,证明了该方法能够较好地计算端板连接的弯矩—转角(M-φ)全曲线,特别是能够非常准确地计算端板连接在节点弯矩小于节点抗弯承载力设计值时的节点转角,从而能够很好地满足结构设计的要求;且该方法计算过程简单,可操作性较强,方便实际应用,为我国钢结构设计规范关于半刚性端板连接的设计计算方法提供了有益补充。
Based on the available research results and the recommendations of relevant design specifications, this paper gives suggestions for the standard details of semi-rigid end-plate connections in muhistory steel frames. The moment-rotation curve and the corresponding simplified theoretical calculation method for this type of end-plate connections have been presented. Comparing with the test results, it has been verified that this method can accurately and effectively calculate the moment-rotation curve. Especially, this method can calculate the joint rotation precisely in the range of moments lower than the design value of the moment resistance and completely satisfies the structural design requirements. The calculation procedure is simple and more efficient for engineering applications, and provides a beneficial supplement to the steel structure design code for the semi-rigid connections.
