1.General Information

Structural Calculations are made according to the EN BS 8118 standard. According to

the technical specification, The Uniform wind pressure: 3 kN/m2 for design. Maximum deflection: 1/200 of clear

span any framing member. Extrusions of Bars, Rods and Tubes: 6060-T66 Alloy comforming to ASTM B 221

The Design method is finite elements method for aluminum framing member

2. Materials

Aluminum frame members are 6060-T6 alloy for facades.

ASTM B 221 Standart

4. Design Criteria

The design wind speed taken from the technical specification that is 3 kN/m2. System

Structural elements self-weight and 12mm glass thickness , load like distributed load that is 0,5kN/m2. Design material is Aluminum materil that is En-AW 6060-T66.

4. Fem Models For Facades Framing

Check for maximum deflection normal and parallel to Curtain Wall Plane. The limit is

1/200 normal to Curtain Wall Plane, other criteria for this design is 1/300 or 3 mm for parallel to Wall plane deflection.

4.1 Type 1 Panel System Analysis

Fem model for Type 1

Shell elements have been identified for wind loads installation only. they have never

been accepted as a diaphragm or structural.
