Publisher Summary The chapter describes the comparison of a series of high-temperature experiments on column webs under transverse compression at different axial load ratios and temperatures with a simplified design approach. The study forms a part of an ongoing project aimed at developing high-temperature models for the behavior of the main components of steel end-plate beam-to-column connections in fire. In this particular phase of the work, the emphasis is on the compression zone in a column web, when transverse compression acts simultaneously with axial compression due to superstructure loading. The main purpose is to construct component-based models of end-plate joints in global numerical modeling of steel and composite building structures in fire conditions. This is the only feasible analytical approach to joint modeling under the simultaneous effects of loading, thermal degradation of materials, and forces due to restraint to thermal expansion. |
