SEISMIC EFFECT ON THE FIRE RESISTANCE OF EXTERNAL WALL ASSEMBLIES FOR WOODEN THREE-STORY APARTMENT BUILDINGS

Abstract

Safety in post-earthquake fire is a key performance for wooden large construction to be built in urban district. Loaded fire tests were carried out on typical external wood based walls rated as one-hour quasi-fire resistance after the application of shear deformations of 1/150rad and 1/100rad simulating a medium and severe earthquakes respectively. The resulting minor reduction of the fire resistance by the shear deformation suggests effectiveness of the post-earthquake fire safety performance of the tested wall assemblies.
