Abstract
Fire resistance tests of loadbearing walls of timber framework with linings of gypsum plasterboards. The results of two fire resistance tests of the loadbearing walls with timber framework with linings of gypsum plasterboards are presented and discussed. One wall was tested under standard fire exposure. Second wall was tested under external fire exposure. The walls had different construction, in particular on the exposed side. Also level of load applied to the wall was different. Big difference in the behavior of the walls was recorded. First wall, even under almost 3 times less loading, collapsed after 45 minutes of the test. The second one did not exceed any of the fire resistance criteria during 132 minutes of the test. It seems that the load redistribution played more substantial role in the first wall behavior than the damage of the studs due to the timber charring.
