【摘要】：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。
[Abstract]:As a new type of industrial building, substation multistory steel structure system has a good application prospect. In order to get standardized and economical substation engineering structure scheme, the construction of steel structure substation in power grid field is popularized. Taking the 110kV substation of Zhonghua as the object, the optimization design of the multi-story steel frame structure was studied. According to the section of the common steel structure members, the initial scheme was given, the different secondary beam spacing and the column spacing comparison scheme were set up, and the PKPM, was used respectively. The influence of different beam spacing and column spacing on the overall performance of the structure is investigated by MIDAS software. The optimal structure layout scheme is obtained. The results show that the adjustment of secondary beam spacing has little effect on the amount of steel used in the structure, while the adjustment of column spacing has a great effect on the amount of steel used in the structure under the premise of satisfying the distribution range of reasonable stress ratio and the reasonable range of deformation. Considering the amount of steel used in the structure, the thickness of floor and the convenience of construction, the optimum scheme of the structure with a column distance of 5.1 m is considered, which provides a technical reference for the popularization and application of the steel structure system in the substation.
