Abstract

Abstract

By calculating the thermo-mechanical coupling analysis model of prefabricated box-plate steel structures, the thermodynamic response was obtained, and the mechanical response analysis of key members and key measuring points was carried out. Combined with the structural characteristics of the prefabricated box-plate steel structure, the failure mode of the structure under fire was proved, and the fire resistance limit of seven fire scenarios was obtained. The results showed that, in single-story structure, the location of fire sources had a great impact on the fire resistance endurance, and when the fire source was in the center, the film stress produced after the middle surface yield of the plate could provide the post buckling strength, which effectively improved the fire resistance time. When the fire source was near the wall, the structure was under uneven and redistributed stress, and the wall bore too much stress, which caused a great reduction of fire resistance time. For a three-story structure, the fire resistance time would be shortened when the fire source was at the bottom, which would achieve earlier when the fire source located in the center position. The fire resistance time of each working condition had reached more than 1 000 s, and there was no obvious mutation at the maximum displacement in each direction. The prefabricated box-plate steel structure showed great stiffness, excellent fire resistance and superior overall performances.
