Concept explainers
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?
