Analysis On Mechanical Property Of Multi Ribbed Slab Structure

Multi ribbed slab structure made up of Multi ribbed composite wall, rib beam and ribcolumn, meanwhile Multi ribbed composite wall is a new type structure, which combinetwo Mechanical properties have large difference of the reinforced concrete frame andaerated concrete block. Based on the Previous research results, study mechanicalperformance and collaborative working mechanismofMultiribbed SlabStructure.Study the stress, strain and deformation of the reinforced concrete frame and theaerated concrete block for the Multi ribbed composite wall under horizontal load orhorizontal and vertical load. And analysis on the mechanical performance, failure modeand cooperative working mechanism of multi ribbed composite wall.By analysis on thestress, strain and deformation can gain the reinforced concrete frame and aerated concreteblocks are interdependent and interaction to resist external loads, and play a important roleinthe strength and stability ofthe multiribbed slab structure.ANSYS software to establish a calculation model of multi-ribbed composite wall,applying vertical load and horizontal and vertical load, respectively, by the yield stress andstrain contours of the following conclusions: Under the vertical load, the stress of the ribbeam change is small, and under the action of horizontal and vertical load rib Liang Yinglichanges is opposite bigger, that rib beam mainly bear horizontal load under the action ofshear force.Under the same load, the filling of multi-ribbed composite wallboard, themaximum of multi-ribbed composite wall stress and strain, respectively, reduce more than2times, visible multi-ribbed composite wall panel to improve the strength and stiffness ofmulti-ribbed composite wall plays a vital role. At the same time, the maximum stress andstrain more concentrated in the junction, beam cross beams, from a security perspectiveshould strengthen the efforts in design. Established the model of Multi ribbed composite wallboard and Multi ribbedcomposite wall, Comparative analysis on the mechanical characteristics of Multi ribbedcomposite wall and Multi ribbed composite wallboard, and by the figure of stress, strainand deformation found that the performance of the Multi ribbed composite wall is betterthanthat ofMultiribbed composite wallboard, illustrated the Multiribbed wall structureofthe "triple" line. And analysis on the change law of mechanical performance about Multiribbed Slab Structure with the increased of vertical load and horizontal load for the actualengineering to provide strong evidence.
