广州新图书馆独立柱是该工程的一个关键部位,抗震性能目标为在罕遇地震下处于弹性状态。介绍独立柱的节点构造、节点有限元分析、嵌固方案及计算长度计算方法。采用在整体结构计算模型中得到构件计算长度的方法,能较好地模拟构件的边界约束条件、较准确地反映构件的承载能力。 The new column of Guangzhou New Libraries is a key part of this project. The seismic performance goal is to be flexible under rare earthquakes. This paper introduces the node structure of the independent column, the finite element analysis of the node, the embedded scheme and the calculation method of the calculation length. Adopting the method of calculating the length of the component in the overall structure calculation model, the boundary constraint condition of the component can be simulated well and the bearing capacity of the component can be more accurately reflected.
