两端销轴型屈曲约束支撑连接节点分析与安装技术研究

摘要

两端销轴连接型屈曲约束支撑是一种新型的结构减震构件，其设计方法和安装工艺有特殊性，给出了设计及安装方法。其次，为考虑加工和安装对节点板造成的初始缺陷，通过有限元软件进行非线性分析验证了其极限承载力。最后，提出了更加合理的安装工艺以保证其安装精度，从而保证了屈曲约束支撑在地震下的耗能能力。%Pin-connected buckling restrained braces (BRBs)are new type of structural seismic reduction components.It requires special design and install methods,which were introduced in this paper.Since fabrication and installation could cause initial defects to the nodal plates,finite elements software was used to perform nonlinear analysis to verify its ultimate capacity.Finally,a more precise installation technique was proposed to guarantee the energy dissipation of the BRBs.
