- Based on TS panel with 26 ga. exterior & 26 ga. interior face (min Fy = 33 ksi) for single span condition.
- Allowable span is the lowest value of panel bending strength, shear strength, deflection limit and connection strength.
- The spans based on panel stress and deflection design criteria are derived from E-72 structural testing. The allowable loads are calculated with a factor of safety of 2.5 and 3.0 for bending and shear stresses, respectively, and deflection limitation of L/240.
- The connection strengths are derived from E-72 structural testing.and the allowable loads are calculated with a factor of safety of 2.5.
- Based on attachment with 14 ga. steel girt with fastener spacing 3"-18"-18"-3" across panel width.
- The structural capacity of the girts are not considered and must be examined independently.
