The floor plan of a building in the preliminary stages of design is shown below. The connec- tions between all members are simple shear connections (shear tabs). This floor space will be used for a restaurant dining area. The floor decking is galvanized 20 gage N3 Formlok with 5 inch slab thickness. Due to the long beam spans, the flooring will consist of lightweight concrete. Calculate the dead load, wD (kip/ft), applied to beam B2 based on tributary load analysis for the given loads and floor span direction. In addition to the weight of concrete, include the self-weight of the corrugated steel decking and allow an additional 35 psf dead load (total of fixed partitions, HVAC, and drop ceiling). Neglect the beam self-weight. Draw an FBD of beam B2 showing the calculated dead load, wD. Report the maximum bending moment (kip-ft) in beam B2 due to dead load. What is the minimum uniform live load, Lo (psf), for this occupancy? Calculate the live load, wL (kip/ft), applied to beam B2 based on tributary load analysis for the occupancy and floor span direction. Draw an FBD of beam B2 showing the calculated live load, wL. Report the maximum bending moment (kip-ft) in beam B2 due to live load. Is live load reduction allowed for this occupancy? Whether or not live load reduction is allowed, what is the adjusted tributary area, KLLAT (ft2), supported by beam B2?
