Abstract

Composite floors using lattice girder normally consists of a temporarily propped precast plank, which contains most of the bottom reinforcement in addition to the lattice girder, which also acts as fully participating permanent formwork in conjunction with the insitu structural topping. In situations where self weight must be minimised, the lattice girder planks can be supplied with polystyrene void - formers bonded to their upper surface. These are then incorporated within the insitu topping. Alternatively, the planks can be manufactured with lightweight aggregate concrete. This type of composite floor is equally suited to use in almost every building type, masonry, steel or concrete structures and particularly those with progressive collapse considerations.
