Abstract

In order to study the basic mechanical property of the new honeycombed-core girderless floor in cast-in-place reinforced concrete, and similarities and differences of the structural performance compared with traditional floor, we carried out the destructive stage loading test on large-scale corner columns supported reinforced concrete honeycombed-core girderless floor. And the thesis conducted finite element analysis in virtue of ANSYS software for solid slab floor, rib floor and honeycombed-core floor. The experiment indicates that honeycombed-core modules cement well with concrete around and participate in the load-carrying; the developing process, distribution and failure mode of crevice in honeycombed-core floor are similar to that of general solid girderless floor. The honeycombed-core girderless floor has higher bearing capacity and better plastic deformation capacity. The finite element analysis manifest that compared with solid slab floor, honeycombed- core floor’s dead load decreases on greater level while deformation increases little, and that compared with rib floor, honeycombed-core girderless floor has higher rigidity. So reinforced concrete honeycombed-core girderless floor is particularly suitable for long-span and large-bay building structure.

Keywords: honeycombed-core module, reinforced concrete honeycombed-core girderless floor, mechanical property, experi-ment study, finite element analysis (FEA).
