Design the reinforced concrete roof of the heavy vehicle repair facility shown. The facility consists of two adjacent halls as shown. Both the halls are equipped with stationary lifting hoists attached to the roof. Each hoist has a lifting capacity of 10,000 lbs. The live load on the roof is 60 psf. Make reasonable assumptions about any missing information. Your design report must be typed with clear sketches. 10' 10' HOIST 1 10 10' HOIST PLAN 45' WALLS 18" THICK BRICK MASONRY Rubrics (total points to be scaled down to 5 points): Component Selection of appropriate structural system with justification(s). Calculation of load effects considering different possibilities. Reinforcement design and design sketches. Grading Criteria System with incorrect or no justification. (0 to 3) Different possibilities not considered (0 to 5) Incorrect design or design sketches of little use for construction. (0 to 5). System with partially correct justification. (4 to 7) Different possibilites considered but incorrect calculations of critical effects. (6 to 15) Partially correct design but sketches have incomplete information. (6 to 15) Appropriate system with correct justification. (8 to 10) Different possibilities considered and critical effects calculated correctly. (16 to 20) Correct design with nearly complete sketches. (16 to 20) Points Total Points
