Comparison and Analysis on Different Structural Systems of Multi-Story Industrial Plants

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.
