sufficient end restraint the stair slab is to be designed for wl2/8. The maximum shear should be ascertained from a simplysupported model of the stair slab. Shear should not be critical in a stair flight. When the stair flight (on plan) occupies at least 60% of the effective span, the permissible span/d ratio may be increased by 15%.

Column with separate lateral ties works out to be cheaper than columns with spiral reinforcement. Axially loaded columns with a low percentage of steel works out to be more economical per tonne of load supported than columns with a higher percentage of steel. The richer the concrete, the more economical is the design. TYPES OF COLUMNS
