Description: This 45-page publication highlights four popular reinforced, cast-in-place concrete floor systems: flat plate, flat slab, one-way joist, and two-way joist.
Preliminary estimates of material quantities (concrete, reinforcing steel, and formwork) for various span and loading conditions help with planning. The effects of different concrete strengths, column dimensions, and floor aspect ratios on material quantities are discussed to facilitate decision making. Charts containing relative cost indices help in making comparisons and selecting the most economical floor system.
