Question
Question 2) A roof system with W12 × 50 sections spaced 8 ft on center is to be used to support a dead load \( (D = 70 \, psf, \, \text{self-weight not included}) \), a roof live, snow, or rain load \( (L_r \, \text{or} \, S \, \text{or} \, R = 50 \, psf) \), and a wind load \( (W = \pm 100 \, psf) \). (a) Determine the maximum combined load (per linear foot) using the recommended AISC expressions for LRFD. Take the load factor on \( L^r \) in combinations 3, 4, and 5 as 0.5. (b) Determine the maximum combined load (per linear foot) using the recommended AISC expressions for ASD.
