Investigating the thermal penetration in structural timber elements exposed to natural fires
Andrea Lucherini, Vladimír Mózer
Objavljeni znanstveni prispevek na konferenci
Oznake: timber structures;fire safety;charring;zero-strength layer;cooling;
This study investigates fire-induced charring and thermal penetration in structural timber elements exposed to natural fire conditions, with a focus on the critical role of the cooling phase. A simplified 1D heat transfer model, based on Eurocode 5 temperature-dependent material properties, is imple ...

This research study investigates the effect of different heating and cooling regimes on the effective cross-section of timber elements exposed to natural fires. An advanced calculation method based on a 1D finite-difference heat transfer model and effective thermo-physical properties is adopted to a ...

This paper presents a numerical study on the effect of the heating and cooling phases on the reduction of the effective cross-section of timber elements, in particular on the evolution of the char depth (300°C isotherm) and zero- strength layer. An advanced calculation method based a finite-differen ...
