Abstract

Abstract

Prefabricated box-plate composite walls have good seismic performances. In order that the box-plate composite walls might applied to practices meet the requirements of fire endurance in specifications, the fire-resistant structural measures were designed and the fire-resistant limit analysis model was constructed. The parameters of the fire-resistant structural measures for the walls were analyzed, which included rock wool thickness, keel spacing and number of rows of openings, gypsum board layer and thickness, cladding sheet types, depth-thickness ratio, and axial compression ratio. The results showed that after the thickness of rock wool exceeded 100 mm, increasing its thickness could significantly improve the fire resistance limit of the walls; raising the thickness and layers of the cladding panels covering fire surface could also improve the fire resistance greatly; the axial compression ratio had a notable impact on the fire endurance; the distance between keels and the number of rows of openings had low impact. According to the above analytic results, the fire-resistant limit optimization design method was proposed, which could provide support for fire prevention design of prefabricated box-plate steel structures.
