Abstract

During rapid cooling by spray water in fire fighting, the deformation of high temperature structural steel was different, it was mainly influenced by water and the steel structure itself temperature. Its bearing capacity was controlled by lower beam flange, and the joint bearing capacity was controlled by T-type plate. The beam temperature had a large effect on its failure mode. The yield and ultimate loads, they reduced about 6.1% and 9.6% between cooled from 400?C and 600?C, and its ultimate displacement reduced around 9.3%, its rotational angle increased about 15%. But their yield and ultimate loads reduced about 26.0% and 24.1% between cooled from 400?C and 650?C, and its ultimate displacement reduced about 18.4%.
