... as the natural fire scenario. Findings The results show that, depending on the fire scenario, the fire resistance criterion can be reached during the cooling phase, especially for the thickest composite slabs. Based on the results, new coefficients are proposed for the original simplified model, proposed...

... performance-based fire design more accessible, a time-equivalent method can be used to approximate a given natural fire event using a single standard fire with a specific duration. Doing so allows for natural fire events to be linked to the wealth of existing data from the standard fire scenario. The purpose...

.... Optimization of a structure can be achieved by using a “Performance-based design”, where realistic fire scenarios are taken into account by means of more or less complex models [parametric fires, two-zones models, computational fluid dynamics (CFD)]. For these so-called “natural fires”, no model for charring...

...Lorenzo Lelli; Jonas Loutan Purpose This paper aims to detail the advanced natural fire simulations that were carried out for the composite steel-reinforced concrete structure of the JTI Building in Geneva, Switzerland. The results of these analyses led to a significant reduction...

...Michal Malendowski; Adam Glema; Zdzislaw Kurzawa; Lukasz Polus In this paper, thermo-mechanical analysis of the structural shell construction exposed to natural fire is presented. A barrel shape coverlet with dimensions of 40m x 80m is a roof system covers the shopping arcade. The braced shell...
