Abstract


With China's rapid increase in the construction of high-rise buildings, with a reinforcing layer frame - core tube structure system in the actual project has been more and more applications. Super high-rise frame - core tube structure system set reinforcing layer may encounter some problems, study reinforces layer architecture of the force of such performance impact of future engineering design has very important significance. This paper re-Bin Poly International Plaza project example belt reinforcing layer frame - core tube structure system of seismic wind resistance were analyzed and studied. Re-Bin Poly International Plaza total height 286.80m, will be built in southwest China's tallest building. Re-Bin Poly International Plaza tower on the ground floor of 58, the main structure of reinforced concrete frame - core tube structure system. To reduce drift angle and vertex displacement, in the twenty-nine and forty four-storey 6 m outrigger trusses refuge layer is disposed reinforcing layer. This project fortification intensity is 6 degrees, but also a high-rise building, the wind load on the structure of a controlling role. To understand the project settings after the seismic reinforcement layer wind resistance, must be set up to strengthen the structural layer performance analysis. This paper re-Bin Poly International Plaza project to establish the overall calculation model, using two procedures ETABS SATWE and mechanical performance of its structure, period and displacement characteristics were analyzed and compared. For a more complex level of force outrigger trusses, while using ETABS and SAP2000 two procedures were carried out checking. The results showed that: the project cycle, the story drift angle and displacement ratio and other indicators are within reasonable limits, there is no apparent structural weak story, the entire structure safe and reliable. In this paper, the model wind tunnel experiments, based on the normative model for calculating wind loads and wind loads wind tunnel test results are analyzed and compared, and the surrounding buildings were considered non-impact and impact on surrounding buildings have two conditions. The results showed that: In this type of wind load control action from high-rise building structure, the model wind tunnel testing has an essential role. This paper re-Bin Poly International Plaza, set different reinforcing layer number and position of the four kinds of working conditions of the structural analysis and comparison of different reinforcement layers set the location and quantity of the structure of the cycle, displacement and force performance . After setting reinforcing layer for reinforcing layer may produce weak layer adjacent layers are analyzed research, analysis, based on the strengthening layer stiffness reasonable choice is suggested.
