The fire resistance limit value of box-type composite walls is one of the important parameters for applying this system. To this end, this article selects different refractory structural measures for the composite wall and analyzes the parameters in each part of the fire-resistant structure, including rock wool thickness, keel spacing, number of opening rows in the keel, gypsum board layers and thickness, etc. The results show that the thickness of rock wool, gypsum board layers and thickness, type of cladding plates and the number of layers, the axial compression ratio have significant influence on the fire endurance. The keel distance and the number of openings rows are almost unaffected. Based on the above analysis, the fire resistance optimization design method and fire resistance calculation formulas of the composite wall are proposed to provide theoretical support for the fire protection design of the box-type steel structural system.
