Description: Two increasingly popular long-span concrete floor systems are covered in this 100-page publication: banded-beam and wide-module 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.
