Research On The Structure Of The Hollow Lapping Column Used In The Transfer-floor

The structural forms are usually changing between upper floors and lower floors in modern tall-buildings. So it's necessary to construct transfer-floor. The lapping column transfer structure is a new form of transfer structure. It generally is suitable to takes in or out-shift buildings.it's very economical,compared with beam transfer structure, thick plate transfer structure, and box beam or girder transfer structure. But methods are not sufficient for structural design.At present the research of hollow lapping column on the construction is very few, it will have the obvious superiority in the economy if the related structure question of hollow lapping column will be solved. Not only reduces the self-weight of structure, saves the material, the choice of structural style is diverse,More importantly is the greatest degree using space, and further reduces the influence of the wind pressure to the building, its application prospect is very broad using hollow lapping column structural style in the projection.This article analysis on partial and the overall of the lapping column transfer structure by the ANSYS software. Pointed out the 1apping column transfer structure stress and the distortion characteristic, also analysis factors that influence its mechanical behavior and crack developing in the partial analysis, gets the size rule of the hole of the lapping column. This article also through aims at the same lapping column selects solid and the hollow two forms to further obtains the respective stress characteristic to be possible for to select the appropriate form in the concrete application to provide the suggestion.The researching outcomes shows that the lapping column transfer structure is economical and applicable,and has a good anti-earthquake performance. It can be widely used in the area with high earthquake intensity.
