Finite Element Analysis Of The Lapping Column Transfer Structure And With Hat Truss, Waist Truss Synthesis Application

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 colnrnn transfer structure is a new form of transfer structure.It generally issuitable 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.This article analysis on partial and the overall of the lapping column transfer structure by the ANSYS software.Pointed out the lapping column transfer structure stress and the distortion characteristic, also analysis factors that influence its mechanical behavior and crack developing in the partial analysis, resulted that thinkess and heigh are very important. In the overall analysis, through has established 28 floor 98.4meter high construction model in ANSYS, analyzed the builds with lapping column transfer structure frame - tube structure stress and distortion characteristic, as well as the influence overall construction stress distorted factor. Had pointed out the question that the lapping column transfer structure when designs in the static function.This article also has carried on the earthquake resistance performance analysis through SATWE and EPDA of PKPM to the model, and resulted characteristic that anti-earthquake performance, the horizontal shear distribution, the rigid stren transition, and the rotation angle between floors, further promulgated the rule respond to earthquake. A sequence of generating hinges is studies by Push-over analysis, as well as base shear. Further the structural seismic performance is evaluated clearly by capacity spectrum method, and compared with beam transfer structure.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.
