Thermal analysis of steel-concrete composite cross sections via CS-ASA/FA
Autor: Dalilah Pires, Rafael Cesário Barros, Paulo Anderson Santana Rocha, Ricardo Azoubel da Mota Silveira
Publikováno v: REM: International Engineering Journal, Vol 71, Iss 2, Pp 149-157
Abstract When exposed to high temperatures, such as in a fire situation, the physical and resistance characteristics of the materials employed in the structure deteriorate as the temperature increases. This fact promotes a considerable loss in the be
