Deflections have been calculated using the algebraic sum of the individual Ix-values.
Bending stress has been apportioned by relative Ix of the appropriate members.
Mullions are assumed to be a single span, simple beam, uniformly loaded and adequately braced against lateral-torsional buckling. All other complex design conditions shall be reviewed by a design professional.
Aluminum extrusions shall be 6063-T6 (Fb=15ksi) alloy. A36 steel reinforcement (Fy=21.6ksi) was assumed. Allowable stresses to be derived per Table 2-21 of Aluminum Design Manual, 2010. Deflection limitation
of mullions shall be in accordance with AAMA TIR-A11 of L/175 or 3/4” (which ever is less) for spans up to 13’-6” and L/240 + 1/4 for all others where L is equal to the span of mullion.
For mullions containing steel reinforcement, the reinforcement is assumed to be installed for the full length of the mullion. A design professional shall be consulted for instances where steel reinforcement is
installed for a partial length of the mullion span.
Windload pressure determinations shall be per the 2012 IBC and ASCE 7-10 (nominal loads) and according to local governing codes. A professional engineer shall be consulted for the most current laws and local
building codes.
Selection of perimeter fasteners and attachment of glazing system to the building structure are project specific and therefore shall be reviewed and determined by a design professional.
Trulite assumes no responsibility for selecting the appropriate systems for specific projects.
