Optimization Analysis And Research Of The Type Of Transfer Floor In High-rise Structure

With the development of modern architecture, the structure of the high-rise building is rapidly developed, which meets the requirements of the different functions of buildings,and meets the seismic fortification and the wind resistance..The choice of the conversion layer has important influence on the safety, the mechanical performance and the engineering cost of the building structure.In engineering design, it has important practical significance for the engineering structure to meet the requirements of the engineering structure and to have good technical and economic performance.This paper which was based on the research on this field in china and abroad and application status of systematic review,was combined with the column for 36 m?36 m of the frame-core tube structure of engineering examples and abstract processing after the example structure.The paper respectively study ordinary reinforced concrete beam type conversion, box type conversion, inclined column conversion, beam type conversion,prestressed transfer beam, wide flat beam conversion of 6 kinds of conversion layer structure.The PKPM analysis model is established with different conversion layer of frame core tube structure of the corresponding according to the calculation results; the mechanical properties of different layer frame core tube structure is studied, the frame of reinforced concrete core tube structure conversion layer respectively in the earthquake intensity is 7 degrees and 8 degrees under the conditions, converting the set is arranged on the first layer to seventh layers, at the same time high conversion layers which were identified as 3, 4, 5, 6, 7 meters,study the lateral stiffness and position of the conversion layer on the stress performance of building structure.In the frame core tube column 6.0 m ? 8.0 m~10.0 m ? 15.0 m span, this paper establish 66 different spans with different conversion layer of the frame core tubecalculation model, through calculation and analysis of conversion layer span change force performance and technical and economic performance of the structure and the influence of the comparative analysis.The paper draws on the conversion layer structure types of optimization method which has reference value for the conclusion.
