Curtain wall performance design

Wind pressure deformation performance of curtain wall: refers to the ability of building curtain wall to maintain normal performance without any damage under the action of wind pressure perpendicular to it, specifically to ensure the strength and stiffness of the curtain wall. Its measurement index is the wind load standard value. The standard value of wind load WO of the conference center is between 3.0kN /m2 and 3.5kN /m2, and the wind pressure deformation performance is Grade 5. Curtain wall air permeability: refers to the air permeability of the curtain wall with its open part closed under the action of wind pressure. In hot summer and warm winter areas, the design requires that the air permeability performance of the curtain wall structure should be at the difference between the internal and external pressure of 10Pa, and the air permeability performance of the fixed part should be at level 4, while the air tightness performance of the open part of the curtain wall should be at level 4.

Curtain wall air permeability: refers to the air permeability of the curtain wall with its open part closed under the action of wind pressure. For hot area in summer and warm in winter. The design requires that the air permeability performance of the curtain wall project is at the pressure difference between inside and outside of 10Pa. The air permeability performance of the fixed part is Level 4, and the air tightness performance of the opening part of the modern curtain wall is Level 4. The in-plane deformation property of curtain wall: refers to the property representing the whole structure of the curtain wall that should be maintained after forced deformation of the curtain wall due to displacement between floors of the building. The main structure of this project is a steel structure, and the plane energy deformation performance of the curtain wall is three times of the limit of the displacement Angle between the elastic layers of the structure, so the plane deformation performance of the curtain wall system is 5 levels. Curtain wall insulation performance: refers to the ability of the curtain wall impedance to heat transfer from high temperature side to low temperature side under the condition of air temperature difference between the two sides of the curtain wall.

According to the thermal calculation for this project, the insulation performance of the non-transparent curtain wall is 8, and the insulation performance of the transparent curtain wall is 5. Curtain wall sound insulation performance: the glass curtain wall of this curtain wall project USES glass RW ≤30dB, aluminum alloy profile lapping and assembling place, steel adaptor and aluminum alloy component connection are set release constraint space, to avoid the noise caused by thermal expansion and contraction of components caused by temperature change, the sound insulation performance of this project is 3 level, respectively.
