SIMULATION OF A COMPARTMENT FIRE EFFECT ON A LOAD-BEARING WALL MADE OF STRAW
Keywords:
load-bearing wall made of straw, compartment fully developed fire, simulation, fire resistanceAbstract
Natural materials, including straw, are increasingly becoming more popular in the construction industry. Load-bearing external walls made of straw bales demonstrated remarkable fire resistance results according to tests carried out abroad. The aim of the paper was to determine the ability of a representative sample of a load-bearing external wall made of straw to withstand the effects of a compartment fully developed fire by simulation using the ANSYS modeling program. The program primarily uses mathematical modeling methods for a virtually created model. The simulation results showed that under the stress of a compartment fully developed fire, a charred layer is gradually formed on the surface of a straw structure, which protects the remaining construction for an expected fire resistance of 120 minutes. The ANSYS program simulation results were comparable to the test performed in an authorized test laboratory.
