Wind load design

Mullion deflection is limited per AAMA TIR-A11-04 deflection is limited to L/175 for spans up to 13'-6" and L/240 for spans beyond 13'-6"
allowable stress for 6063-T6 aluminum alloy = 15000 p.s.i. allowable stress for A-36 steel = 21600 p.s.i.
maximum deflection was based on the following equation:

Dead load design

maximum bending moment was based on the following equation:

assumptions:

W = total uniform load

L = length of mullion between anchors E = 10 X 106 p.s.i.

I = moment of inertia of the mullion M = maximum bending moment

* mullions are assumed to have equal size glass lights each side check with local code requirements for acceptance of AAMA TIR-A11
