Method and device for reducing wind pressure to building

Abstract

The invention discloses a method and a device for reducing a wind pressure to a building, which solve problems about the method and interface for accessing conventional structural calculation and analysis software and problems about the method and the device for handling noises, rainy weather and condensed water during the reduction of the action applied by the wind pressure onto the building. Passages are arranged between the windward side and leeward side of the building so as to make wind run through a building body; positions, number and cross-sectional sizes of the passages on the surfaces of the building are determined to acquire input parameter values required by the conventional structural calculation software; and the conventional structural calculation software is utilized to finish the structural calculation, force analysis and the design of a structure and components of the building. Therefore, the method and the device for reducing the wind pressure can be actually applied to engineering, engineering cost is reduced and structural security is improved; mufflers and rainwater and condensed water drainage systems are arranged in the wind passages; and the method and thedevice are mainly applied to super high-rise buildings and high-rise buildings of shallow rectangular shapes, particularly regions with strong wind and low earthquake intensity.
