Problem One- Final exam Determine the adjusted nominal reference design values and the nominal strength capacities of a Douglas fir South (Select structural) beam 8 x 12 inches used in a system of floor beams supporting a combination of dead, live and snow loads! Conditions are no incisions. Normal temperature range and the dry service conditions - The floor is attached to the top of the beam. Problem two- Final exam Given the Douglas fir South vin of problem one, the beam span is 24 feet long. Determine the maximum factor unit load (lb/ft). If the 8 x 12 inch beams are part of a floor system 3 feet apart on center and simply supported at their ends, as shown in the figure below. Determine 1- The distributed load (lb/sqft) 2-The load that the beam A-B applies to each end column, "Pu" at A and B. 3' 31 A Column Column 8X12 B 8x12 24'
