Composite Beams using Fibre Reinforced Concrete (FRC) Profiled Slabs

澳大利亚建筑业目前正在将大跨度梯形压型钢板引入钢-混凝土组合框架建筑的组合楼板中，以提高效率和经济性。 当板中的肋与钢梁（次梁）正交时，钢梁与组合板之间的剪切连接的完整性由于过早失效而受到损害。 该项目旨在研究钢纤维增强混凝土在这些板中的创新应用，这些板在其他应用中（在新南威尔士大学和其他地方）已被证明在承受各种荷载制度时具有上级强度特性。

The Australian construction industry is currently introducing long-span trapezoidal profiled steel sheeting for the composite floor slabs in composite steel-concrete framed buildings, in order improve efficiency and economy. When the ribs in the sheeting are orthogonal to the steel beam (the secondary beam), the integrity of the shear connection between the steel beam and the composite slab is compromised by premature failures. This project aims to research the innovative use of steel fibre reinforced concrete in these slabs, which has been shown (at UNSW and elsewhere) in other applications to possess superior strength properties when subjected to a variety of loading regimes.
