Thermal Actions For Structural Analysis Of An Office Building With Large Open-Spaces

Retrofitting and refurbishment of existing buildings is an everyday challenge for fire safety engineers, and maybe even more for structural engineers that must deal with buildings made following old codes and practices. To respond to these subjects (verification of structural strength, reduction or optimization of passive protection costs), engineering studies are increasingly using performance-based methods. This article describes a study carried out for the existing luggage sorting centre located in Geneva Airport in which an advanced method was used to assess the structural behaviour of the steel structure in case of fire.
