| Popis: | This paper presents the application of a structural fire model to a twelve-storey office building in Auckland, which was one of the first projects in New Zealand to use long-span cellular floor beams. The structural fire model that was employed is known as the slab panel method (SPM), which is an extension of the Bailey tensile membrane model. Owing to the fact that the cellular beams had been optimised for structural efficiency, there was little reserve of strength in fire conditions, which resulted in the SPM predictions of peak deflection being supplemented by finite element simulations for a range of design fire severities. The simulations indicated that there was a tendency for the bottom flange of the asymmetric cellular beams to displace laterally, which resulted in the beams that form the slab panel supports requiring vertical stiffeners. Nevertheless, from these analyses it was demonstrated that the passive fire protection could be eliminated from the long-span secondary beams, with only ... |
