变电站多层钢结构体系作为新型的工业化建筑形式具有良好的应用前景,为了得到标准化、经济化的变电站工程结构方案,推广电网领域钢结构变电站的建设,以中化110k V变电站为对象,对其多层钢框架结构方案进行优化设计研究,按照钢结构常用构件截面给出初始方案,设置不同次梁间距、柱距对比方案,并分别利用PKPM、MIDAS软件对各方案计算分析、校核对比,考察不同梁距、柱距对结构整体性能的影响,进而得到最优结构布置方案。分析结果表明,在满足合理应力比分布范围及合理变形范围前提下,次梁间距的调整对结构用钢量的影响不大,柱间距的调整对结构用钢量影响较大;综合考虑结构用钢量、楼板厚度及施工便捷性,柱距为5.1m的结构方案为最优方案,为变电站钢结构体系的推广应用提供了技术参考。
The substation multi-layer steel structure system has a good application prospect as a new type of industrialized construction form. In order to obtain a standardized and economical substation engineering structure scheme, and to promote the construction of steel structure substations in the power grid field, Sinochem 110kV substation is the object, and its The multi-layer steel frame structure scheme was optimized for design study. The initial scheme was given according to the commonly used structural section of the steel structure, and the different sub-beam spacing and column spacing comparison schemes were set up. The PKPM and MIDAS software were used to calculate, analyze and compare the various plans. The influence of different beam spacing and column spacing on the overall performance of the structure was investigated, and the optimal structure layout scheme was obtained. The analysis results show that under the premise of satisfying the reasonable stress ratio distribution range and reasonable deformation range, the adjustment of the spacing of the secondary beams has little effect on the amount of steel used in the structure, and the adjustment of the column spacing has a great influence on the amount of steel used for the structure; The steel structure, floor thickness, and construction convenience are the optimal solutions for a 5.1m column spacing scheme, which provides a technical reference for the promotion and application of substation steel structure systems.
