Hybrid wood/steel elements under fire
Description
The main objective of this paper is to present a computational model for the fire resistance of wood/steel hybrid elements. Different design solutions will be presented. The most important factors for fire safety in hybrid elements are the thermal effects degradation and the charring depth formation in wood materials, and also the heat conduction extremely well in steel material. Unprotected steel elements under fire condition may suffer serious damage. The use of hybrid wood/steel elements could increase both structural strength and stiffness. Wood could be considered as an insulating material, the core section could remain at low temperature, function of fire exposure time and element cross section size. All presented results will permit to evaluate different design solutions, which facilitates the fire design of wood/steel hybrid elements. The presented study was conducted in order to articulate the best constructive solution using the finite element method.
