Resumo(s)
Three different solution models were used to compare the fire performance of LSF walls with void cavities. The first solution method considers the air-structure interaction in the cavity region. The second solution method considers the existence of interface elements for the radiation heat transfer in the cavity region allowing the bulk temperature prediction. The third solution method considers the convection and radiation in the cavity region with a prescribed bulk temperature from experiments (hybrid). Solution methods 1 and 3 give a smaller root mean square error (RMSE), when compared with solution method 2. Solution method 3 gives a better approximation because can capture the main fire events during fire testing, such as the cracks and fall off.
