Abstract

Sprayed fire resistive material (SFRM) is intended to thermally protect structural steel elements during a fire. The integrity of the SFRM may become compromised during an earthquake due to yielding and damage in the underlying steel structure to which the SFRM is bonded. This in turn can influence the post-earthquake fire performance of the SFRM. Tests were performed to evaluate the bond performance of SFRM on steel plates subjected to tensile yielding. The test results show rapid degradation of the bond strength of SFRM to steel plates with increasing tensile yielding. Test results also show marked differences in bond behavior between wet mix and dry mix SFRM and between coatings on steel with a mill finish as opposed to a sand blasted finish.
