SHEAR STRENGTH OF A BOLT AT ELEVATED TEMPERATURE AND AFTER HEATING AND COOLING PROCESSES

Abstract

In this study, shear-loaded experiments on 4.8, 8.8, and 12.9 class bolts were conducted under both elevated temperatures and ambient temperature after heating and cooling processes. The test results on the reduction factors of shear strength at fire and the residual shear strength at post-fire were accumulated. Those test results contribute to the evaluation of the structural fire-resistance performance on the bolted connections.
