High construction costs today challenge the en- gineer to produce sound money-saving designs with- out too rigid an adherence to conventional patterns. The value of good engineering. judgment is empha- Slab band constructron IS suggested for cutting cost, since expensive beam forms may be elimin-ated, story heights are decreased and pipe and conduit installations are simplified. Ideal layouts and dimensions for slab band construction are noted and desisn for shear resistance is considered. The author cites personal experience in the design of floor framing for a l2-story 500-bed hospital. Five different designs (all illustrated) were prepared and cost comparisons made. dropped beam, Of the five (slab band, conventional concrete beam and slab and two types of encased structural steel) the slab band system proved least expensive, with drop-ped beam construction a close second.
