The Mechanics Performance Analysis On A Lapping Column Transfer Structure

The lapping column transfer structure is a new form of transfer structure in China, it's very economical , compared with beam transfer structure, thick plate transfer structure, and box beam or girder transfer structure, firstly, a little amount of construction materials is used to make structure transformed, secondly, A great amount of construction measure expense is saved ,because no special construction methods are needed . thirdly, A great amount of construction area is saved .because the lapping transfer member scarcely impropriate any floor area.In this thesis, a lapping column transfer structure building with 14 floor forced by vertical loads is studied, applying SAP2000 FEM program. And the deformation law of the floor or the shear wall, the distribution of the internal force and stress on the floor or on the shear wall are founded out, And some suggestions are given out for structure design later. On the base of this analyzing , The deformation, the stress on the floor, and the rotation angle of the lapping column affected by the thickness .height and the ratio of height to width are studied,. And the static equilibrium equation is found out In order to evaluate the dynamic behavior this transfer structure, another two building with beam transfer structure and lapping column transfer structure are studied, and the results demonstrate that the anti-earthquake performance, the horizontal shear distribution, the rigid strength transition, and the rotation angle between floors are much better than the beam transfer structures, so the lapping column transfer structure can be applied in earthquake area.The researching outcomes shows that the lapping column transfer structure is an economical and applicable , and has a good anti-earthquake performance. It can be widely used in the area with high earthquake intensity. The result in this thesis can be referenced in other structure design.
