Abstract and Keywords

Abstract: This paper studies the lateral static behavior of the steel frame structure of the single-storey modular substation auxiliary building in a substation project. The module units of the auxiliary building are connected with the foundation by the base plate and anchor bolts. High strength bolts and split bolts are used to connect the flanges and webs of columns respectively between module units. The construction is simple and the construction space is good. In this paper, ABAQUS software is used to conduct a nonlinear pushover analysis of the steel frame structure of the modular substation auxiliary building. The static performance of the structure and its joints is investigated, and some measures to improve the performance of the connection joints are given, which can provide reference for similar projects.

Keywords: substation; modular auxiliary building; connections; finite element simulation; static performance; connection structure optimization

摘要和关键词

摘要: 文章针对某变电站工程中单层模块化变电站辅助用房钢框架结构的侧向静力性能进行研究,该辅助用房模块单元与基础之间采用地脚螺栓底板连接,模块单元之间采用翼缘高强螺栓和腹板对穿螺栓进行连接,施工简便且具有很好的施工空间;通过 ABAQUS 软件对模块化变电站辅助用房钢框架结构进行非线性推覆分析,考察结构及其节点的静力性能,给出一些连接构造的性能提升措施,可为类似工程提供参考。
