Design Method Of Composite Slab With Precast Ribbed Panel

In order to comprehend seismic behavior and design method of the Concrete Composite Slab with Precast Ribbed Panel. this paper have a experimental research on seismic performance of composite slab with precast ribbed panel, an analysis of bearing capacity of the slab, a thorough study on design method of the slab during construction stage and serviceability stage.Experimental study, theoretical analysis, finite element analysis are the main methods used in this paper.This paper had a statistical analysis on concrete superposition slabs at home and abroad, the slabs had been classified. Compared with common composite slabs, the advantage of composite slab with precast ribbed panels had been summarized.Composite slab with precast ribbed panel have been studied with experiment, theoretical analysis and finite element method. The experiment was field loading test, balance method was used in theoretical analysis and ABAQUS was used in finite element analysis. By researching, failure model was more clear. Bearing capacity formula was put forward, many improvement measures has also been put forward to solve problems which were discoveredThe panel whose length was3300mm or6000mm was taken for example to research the composite slab with precast ribbed panel.The method to calculate the bearing capacity,crack width and deformation were put forward. The design method based on standard drawings was also put forward for designers’ reference.16full-scale specimens were designed for researching on seismic behavior and inner forced plate of composite slab with precast ribbed panel. Method of loading was reversal load pattern. According to result of the experiment, mechanical behavior of minus moment steel bar, perforation steel bar and crack-prevention steel bar was grasped preliminary, this paper took the study of seismic behavior on composite slab with precast ribbed panel finished by Chen Zhonghan and the experimental study on seismic performance of the superimposed slab shear wall finished by Lian Xin as reference, and put forward some structural measures about seismic design.Panels, the width of which were600mm and1200mm were increased in the coming design task of standard drawings. Based on it, this paper introduced the design method of standard drawings for composite slab with precast ribbed panel.Bearing capacity of original section was checked calculation, new section was designed based on the result of checking calculation to meet the dynamic needs of the bearing capacity, crack width and deformation after increasing the size of panel.The popularization and application of composite slab with precast ribbed panel in Lanzhou was summarized, special method was used in economic analysis on composite slab with precast ribbed panel, cast-in-place slab and composite floor with profiled steel sheet. Time factor was considered. Cost of composite slab with precast ribbed panel was fully understood. The popularization and application of composite slab with precast ribbed panel would be further promoted. Social benefit of the slab was also summarized.
