“…Xiaonong et al (2020) pointed out the advantages and disadvantages of fire temperature field at different high temperatures and the important influence of flame radiation in large space fire through the study of high temperature performance of aluminium alloy. Meng et al (2021) studied the shear performance of high-performance fire-resistant steel structures and found that with the increase of temperature, the failure mode of bolt joints changed from compression failure of hole wall to shear failure of screw. Jinghai et al (2020) analysed the mechanical properties of the composite Suo-qiong structure under high temperature, and based on the parameter analysis of the mechanical properties of the composite cable dome structure under high temperature fire, some suggestions for structural fire resistance analysis were put forward.…”

In this paper, the stability analysis method of the elastic beam-column under a load of high temperature is deduced from normal temperature and taking the beam-column with a protective layer in high temperature under the action of uniform load and concentrated load as the example. We analysed the variation law of the stability of the beam-column with temperature changed and use the ANSYS software to analyse the stability of the beam-column with the same condition, and verified the correctness of the method we deduced. Through stability analysis, the stability of the structure under the uniform load is better than that under the concentrated load.

“…According to the testing results, they obtained calculation models used for reduction coefcients of yield strength and the initial elastic modulus of ordinary high-strength bolts and fre-resistant high-strength bolts at high temperatures. Meng et al [29] investigated the shear performance of bolted joints fabricated with BFRW10 highstrength fre-resistant bolts. Tey found that the failure mode of bolted joints changes from compressive failure on the bolt hole to shear failure of the bolt screw with increasing temperature.…”

The use of fire-resistant steel is an effective way to alleviate fire safety issues in steel structures. Considering the limited research on bolted joints fabricated from fire-resistant steel, this study presents the results of the experimental investigation on the mechanical behavior of 40 specimens of bolted joints at room temperature and elevated temperatures (20°C∼700°C). These specimens are assembled with fire-resistant steel plates and fire-resistant high-strength bolts (or ordinary high-strength bolts). The mechanical behavior of these specimens was investigated, which included the failure mode, deformation performance, and degradation of bearing capacity. The experimental results show that the treatment of the friction surface (specifically, impeller blasting and sprayed hard quartz sand) has a negligible effect on the ultimate strength of specimens and a relatively significant effect on the slip strength. In addition, reduction factors of the tensile strength (KN) and slip strength (KS) for both fire-resistant bolt specimens and ordinary high-strength bolt specimens decrease with the increase in temperature, especially in the case of elevated temperatures ranging from 400°C to 700°C. Prediction models with different reliability degrees are proposed to calculate the degradation of tensile strength under elevated temperatures, which has the potential to be used for the fire-resistant design of steel connections and structures.
