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
