1.3 DELIVERABLE: Obtain the roof slope from thestructural or architectural drawings. Determine the unreduceddesign live load, Lo (ASCE 7-16 Table 4.3-1), and the reduced rooflive load, L, (ASCE 7-16 4.8). For L, consider only reductions dueto the slope (do not use reductions for tributary areas even thoughit is allowed by ASCE 7- 16 4.8.2). Identify L, as a LOAD PATTERNnamed 03_LIVEROOF
