Editor's Notes
- Comprehensive design exposure to two very different structuresChance to explore various structural systems
- W-section: majority of the flexural capacitySteel decking: selected to satisfy span lengths and fireproofingConcrete slab: flexural capacity, transfers load, fireproofing for the steel deckingShear studs: transfer shear forces, diaphragm action, brace flange – local buckling, brace beam – ltb Welded wire fabric: temp and shrinkage
- Makes use of the slab as a structural elementProvides lateral bracing for the beams along their length to prevent ltbEfficiency is improved – lighter, more economic structural systemIf large amounts of studs are neededConstructing using shored spans
