4 Technical requirements
Glass curtain wall design should be carried out in accordance with JGJ102, and other types of curtain walls such as porcelain plate curtain wall, stone slab curtain wall, etc. can be implemented as a reference. Note: When the curtain wall height is greater than 150m and the earthquake cracking intensity exceeds 8 degrees, structural and seismic tests should be carried out, and it can be adopted only after meeting the design requirements. 4.1 Physical performance
The physical performance grade of the curtain wall shall be selected according to GB/T15225 based on the geographical and climatic conditions of the building area, the building height, size and environment, and the importance of the building. 4.1.1 Wind pressure deformation performance
Grading shall be carried out based on the safety detection pressure difference P, and the grading index shall comply with the provisions of Table 1.
Wind pressure deformation performance classification
P1≥5.0/5.0P3224.0/4.0>P,23.0|3.0>P3≥2.0/ 2.0>P3≥1.0Note: The classification value in the table indicates that under the action of this standard value of wind load, the relative deflection value of the main load-bearing rods of the curtain increase should not be greater than L/180 (L-rod length), and its absolute deflection value is within 20mm: If the absolute deflection value exceeds 20mm, the pressure value corresponding to 20mm is used as the classification value. 4.1.2 Rainwater leakage performance
The pressure difference P of the previous stage where leakage occurs is used as the classification basis, and its classification index value should comply with the provisions of Table 2. Table 2

Note: When designing, the P value of the fixed part is determined according to the data obtained by dividing the standard value of wind load by 2,25. The grade of the openable part corresponds to the rated part. 4.1.3 Air permeability performance
The air permeability of 9 under standard conditions with a pressure difference of 10Pa is used as the basis for classification. The classification indicators should comply with the provisions of Table 3. Table 3
