Analysis On Mechanical Performance Of CBM Cast-in-situ Hollow Concrete Floorinfluenced By Geometric Parameters

The CBM cast-in-place reinforced concrete hollow floor which hasemerged in recent years is a new type of floor systems. Compared with thetraditional plate beams floor , The CBM cast-in-place reinforced concretehollow floor has characteristic such as a light-weight, span, structural typeselection free, saving energy, reducing cost, construction efficiency ; Dueto its advantage it has been widely applied to various practical engineeringnow,and achieved good economic benefit and social benefit. But because ofits appearance in recent years, so the theoretical and experimental aspects isstill in just the start stage, which has seriously restricted its application anddevelopment in practical engineering.Based on the Research status of the CBM cast-in-place reinforcedconcrete hollow floor,this paper completed the work as follow:First of all,author introduced several common hollow floor in thedomestic,and discused detailedlythe structure characteristics, constructiontechnology and economic benefits for detail of the CBM cast-in-placereinforced concrete hollow floor.Secondly, Using ANSYS finite element software builded a 1/4 modelsof cast-in-place reinforced concrete hollow floor model,simulated themechanical propertics of hollow floor in uniform loads,and contrastedwith the test of Southeast University to determine the feasibility of finiteelement model.Finally, contrasted with parametersin different rib wide and plate thickness toanalyse influence of mechanical propertics for CBM cast-in-situ concrete hollowfloor. Combining with the Standardto put forward the reasonable results oftheseparamet e r s .
