THE EXPERIMENTAL RESEARCH ON FIRE-RESISTANT PERFORMANCE OF HIGH-STRENGTH BOLT CONNECTION
The experimental researches on tensile performance and shear performance in high temperature were carried out for the fire-resistant performance of high-strength bolt connection. The experimental research of shear performance for connection in high temperature reveals the effect of temperature on the mechanical performance of high-strength bolted steel, and then the calculation formula of the mechanical performance index can be fitted out through the contrastive analysis. The research on shear performance of high-strength bolt in high temperatures presents the effect of temperature on its sliding load and limit load, then the calculation formula of sliding load and limit load for shear connection at high temperature can be put forward through the contrast analysis on the basis of the test results. The research results of this paper provide a theoretical foundation for the research of fire-resistant performance of steel structure joints, provide a prerequisite for the overall fire-resistant design of steel structure, and provide an important reference for the formation and revision of relevant codes, and it has great facilitation on improving and developing the fire-resistant design methods of steel structure.
