Authors Leonard, J.E., Macindoe, L., Watson, K.B., Bennetts, I.D., Kelly, M.H., Clayton, T.G. and Baines, D. / Buildings in bushfire prone areas must be positioned or designed to resist the effects of a bushfire, which may include flame impact directly on the building envelope. In April 2010, an experimental steel framed steel clad building was tested under flame zone conditions using an outdoor bushfire flame front simulator. The roof and floor systems withstood the exposure with minimal damage, while the wall system showed some thermal and structural failures. Further wall tests were conducted using the Radiant Panel Test Facility at CSIRO Highett, Victoria. Four wall panels were tested in August 2011 using a variety of insulation details. The test results are described and compared with those from the full-scale outdoor simulator test. The implications for the performance design of steel-framed houses to resist severe bushfire exposures are discussed. In: Australasian Structural Engineering Conference, 2012.
