A numerical study on the response of steel beams to fire and explosion is presented in this paper. First, a unified computing model, which can be used to simulate the behaviour of beams under four loading scenarios that involve fire and explosion or impact, is constructed. The proposed technique allows complete transparency of the influence of the various parameters on the structural behaviour. Second,...
This paper mainly involve 3 parts: 1) To apply the minimum principle of acceleration in dynamics of elastic-plastic continua at finite deformation to the statics problems, a computing model is presented for the restrained steel beams exposed to the fire. In this model, both effects of large deflection and thermal expansion deformation are taken into account, and the constitutive equations with the...
