Abstract

The invention provides a wind adaption design method of a super high building. The method is aimed at reducing wind loads and / or reducing wind load effects. The designed building is enabled to be equipped with changeable aerodynamic appearance. According to the method, the self-adaption capability of the building to the wind effects under strong wind conditions can be improved; the design loads of an anti-wind structure system can be reduced; and moreover, the demand for optimizing aerodynamics in design of the building appearance is reduced.

Description

technical field [0001] The invention relates to super high-rise buildings and structural design. Background technique [0002] A major challenge in the design of supertall buildings is the issue of wind effects. The super high-rise buildings defined here refer to high-rise buildings with a height of more than 200 meters or an aspect ratio greater than 6. Such buildings are more sensitive to wind effects. [0003] Due to the high wind speed of high-rise buildings, the long natural period of super high-rise structures, and relatively low structural damping, wind loads are often the main loads controlling the design of structural lateral systems. Studies have shown that aerodynamic optimization of building shapes can greatly reduce structural wind loads and wind-induced structural vibrations, bringing considerable economic benefits. In the design of many super high-rise buildings, aerodynamic optimization has become the key to the success of the design. The specific methods...
