钢框架节点板受压性能分析

The Analysis of the Compression Performance of Gusset Plate in Steel Frame

钢框架结构节点支撑连接方式以板式连接为主,其设计具有不同于GB50017-2003《钢结构设计规范》中规定的普通钢结构节点板的特殊性。建立钢框架结构连接支撑的典型节点有限元模型,进行节点板受压性能分析,总结了节点板厚度、无支长度、支撑连接角度和加劲板厚度对节点受力的影响规律。结果表明,节点板厚度和无支长度对于节点板受压性能影响较大,支撑连接角度影响较小。

Due to the particularity of the steel frame structure, the design of gusset plate fiame beam column joints is dit＇terent from Code for Design of Steel Structures （GB50017-2003）. In this paper, the compression performance of typical gusset plate frame beam eolumn joints in steel frame structure is studied by finite element analysis model. The effect of the main parameters and the node plate for steel frame structure of the gusset plate are investigated. Results show that, supporting connecting angle has little effect on the gusset plate, while the gusset plate thickness and the unsupported length play a major role.
