节点是框排架结构抗震的关键部位,本文通过试验分析了外包钢双肢柱装配武节点的受力特点,提出加强连接板,使塑性铰位置转移,可有效地提高接头的延性。在此基础上,拟定了节点抗震设计方法和施工要求,为工程设计提供依据。 The node is the key part of the earthquake resistance of the framed and bent structure. This paper analyzes the force characteristics of the assembly joints of the double-limb column of the steel by experiments, and proposes to strengthen the connecting plate to shift the position of the plastic hinge, which can effectively improve the ductility of the joint. On this basis, the seismic design method and construction requirements for the joints are formulated to provide a basis for engineering design.
