Three-dimensional model of non-load bearing LSF walls under fire
| Resumo: | The present work presents numerical study with the aim of analysing the fire performance on LSF non load bearing walls. Numerical validation of the full-scale fire test developed by Anthony Deloge Ariyanayagam, Mahen Mahendran [1] was developed using transient thermal analysis, assuming perfect contact between different materials to determine the fire insolation criteria (I). The insulation criterion is defined by the average temperature or by the maximum temperature determined on the unexposed side of the wall. Two extra 3D numerical analysis were developed with the objective of understanding the thermal effect of the cavity size and the number of protection layers. Two different types of errors were used to compare the numerical and experimental results. The absolute relative error has been applied to compare the fire resistance time obtained by the numerical simulation and the fire test. The Root mean square (RMS) was used to compare the time history temperature error, determined on different locations of the wall section on specific points. |
