Whenever fire unprotected steel members are attached to a fire-protected steel member and penetrate its passive fire protection, additional heat will be conducted to this member during a fire. This can result in a local hot spot in the primary member that may reduce the actual fire resistance. The wide variation in loss of fire resistance is because geometries can vary, and in particular because of the influence of the section factors of the attachments. The influence of the partial protection was experimentally and numerically studied at the Czech Technical University in Prague. Four partially fire-protected plates were heated according to the nominal standard fire curves in a small horizontal furnace. A Finite Element Analysis (FEA) was validated and was applied to a numerical study of an unprotected steel beam under fire separation sealing, which was connected to a steel column. A description was prepared of the development of heat for various fire exposures under fire protection of different lengths and nonlinear thermal conductivity with different section factors.
