Analisi degli effetti tensionali indotti da incendio su strutture tridimensionali di acciaio, ricoperte con materiale isolante

A numerical procedure is presented for thermomechanical analysis of three-dimensional steel structures subject to fire. The procedure is based on finite element method and weighted residual approach in Galerkin form. It is applied for modelling the time transient of a fire together with subsequent phase of fire extinguishment
