摘　　要：在采用钢筋混凝土结构和钢结构的传统立式工业厂房中,当其跨度比较大、荷载比较大时,采用钢-混凝土组合结构体系能带来更好的综合效益。针对立式粮仓厂房堆放粮食、承受荷载较大的特点,以海南省某立式粮仓厂房框架结构为例,对其采用钢筋混凝土结构、钢结构和钢-混凝土组合结构分别进行方案设计并统计三种结构体系的经济指标。利用有限元计算软件对结构进行静力推覆分析和动力弹塑性时程分析,对比不同结构体系的承载力、抗侧刚度、层间位移角、出铰情况、破坏形式等指标。分析结果表明,钢-混凝土组合结构体系以其优越的受力性能、便捷的施工性能以及良好的综合效益,在立式工业厂房中具有广阔的应用前景。In traditional vertical industrial workshops that use reinforced concrete structures and steel structures,when the span is relatively large and the load is relatively heavy,the use of a steel-concrete composite structure system can bring better overall benefits.As a place where grain is stacked,the vertical granary workshop has the characteristic of bearing a relatively large load.In order to investigate the comprehensive benefits of different structural systems used in multi-story industrial workshops,a granary frame structure in Hainan Province was taken as an example.Based on the design software,the reinforced concrete structure,steel structure and steel-concrete composite structure were adopted for scheme design,and the economic indicators of the three structural systems were calculated.The static pushover analysis and dynamic elasto-plastic time history analysis of the structures were carried out by using the finite element analysis software.Performance indexes including the load-bearing capacity,lateral stiffness,story drift and distribution of plastic hinges of different structural systems were compared.The analysis results exhibit that the steel-concrete composite structure has broad application prospects in multi-story industrial plants due to its superior mechanical performance,convenient construction performance and extraordinary comprehensive benefits.
