摘　　要：水电站主厂房以钢筋混凝土结构为主,钢结构形式能更好地适应厂房地震烈度高、跨度大、吊车吨位大的特点,因此有必要研究钢结构厂房在水利行业主厂房的应用。结合某高烈度水电站主厂房的工程实例,选用钢结构和钢筋混凝土两种厂房结构形式进行计算,分别阐述两种厂房结构的设计原则、设计荷载和变形控制,最后从吊车荷载、位移允许值、柱底力、厂房空间利用、施工速度、工程造价、抗震性能等几方面进行对比分析。研究成果表明,钢结构厂房具有明显的优势,可为高烈度区水电站主厂房设计工作提供借鉴。Reinforced concrete structures have traditionally been the primary choice for the main powerhouses of hydropower stations.However,considering the challenges of high seismic intensity,large spans,and heavy crane loads,steel structures offer a promising alternative that better accommodates these demands.This study examines the feasibility and advantages of steel structures for main powerhouses in the hydropower industry.A hydropower station located in a region of high seismic intensity is used as a case study,where both steel and reinforced concrete structural schemes are analyzed.The design principles,loading conditions,and deformation control measures are systematically examined for each option.A comparative evaluation is conducted across several aspects,including crane loads,allowable displacements,column-base forces,spatial utilization,construction speed,project cost,and seismic performance.The findings highlight the significant advantages of steel structures under these conditions,providing valuable guidance for future designs ofmain powerhouses in high seismic regions.
