Inelastic Behavior of Protected Steel Beams and Frames in Fire

摘要

In the past, the authors studied the fire resistance of protected steel columns in fire. In this study, the inelastic behaviors of protected steel beams and frames that are exposed to a thermal history similar to that obtained in a standard furnace fire test are investigated numerically by the method of finite element elastic-plastic-creep analysis, including thermal and mechanical properties of steel under high temperatures and geometric nonlinearities of steel members.
