Study On Antiseismic Performance Of Structure With A Src Transfer Beam Located At A Higher Level

The structure with a SRC transfer beam at a higher lever is one kind of vertically irregular and complicated style so that its seismic mechanism is not specific. So it's difficult to design this kind of structure. At present, the research on the structure are insufficient in academic circles and engineering, especially, the SRC transfer beam's research are really few.Utilizing the seismic response spectrum and the finite element analysis theory, This paper has conducted the thorough research to antiseismic performance of the structure with a SRC transfer beam at a higher lever.Using American CSI Corporation' s general spatial finite element analysis software SAP2000, has established 4 three-dimensional finite elements computations structural model, mainly has analyzed overall structure dynamic behavior and antiseismic performance as the SRC transfer beam at different position. To emphasize the of antiseismic performance' s superiority of the structure with a SRC transfer beam , the antiseismic performance research between a structure with a SRC transfer beam with another a structure with a RC transfer beam has also made.Then , Draws the following important conclusion: (1), The higher order inspiring seismic influence on a structure with a SRC transfer beam is deep ; (2) , SRC transfer beam establishes higher, the structureintegrity is worse, and its antiseismic performance is more disadvantageous; (3) To compare a structure with a SRC transfer beam with another structure with a RC transfer beam, the former antiseismic performance surpasses the latter.Regarding the complex high-rise structure optimized design, the improvement in structure antiseismic performance, the enhancement of structure synthesis economic efficiency and social benefit, these conclusions are of vital significance.
