How to determine the wind resistance performance of building curtain wall
The wind resistance performance of open building curtain wall should meet the design requirements. The wind pressure performance rating index P3 shall comply with the requirements of 5.1.1.1 of this standard
1, the curtain wall of the wind pressure performance indicators should be based on the wind wall of the wind load standard value Wk to determine its target value should not be less than Wk, and should not be less than 1.0kPa. Wk shall be calculated in accordance with GB 50009. 2, under the action of the wind pressure performance index value, the curtain wall supporting system and the relative deflection and absolute deflection of the panel should not be greater than the requirements of Table 1 below.
