Experimental Study on Honeycombed-core Reinforced Concrete Hollow Floor with Four Edges Simply Supported

摘要

Honeycombed-core reinforced concrete hollow floor is one new-style reinforced concrete hollow floor system. Its rigidity, bearing capacity and so on are analysed by the relevant experiment in this paper. The distributed state of the internal force of the floor in the course of loading and the crack, deformation, bearing capacity and strain of the members are tested by the experiment of around simply-supported Honeycombed-core reinforced concrete hollow floor. Some conclusions are proved by the experiment that deformation of the floor at elastic stage is relatively small, the whole rigidity and cracking resistance of the floor are good, honeycombed-core models are received the loading at elastic stage and the mechanical behaviour of the whole slab can be improved by the width of the flat girder. So the floor can be applied to construction work extensively because of its good mechanical behaviour.
