Description
Description

A one-way concrete band slab and joist system is an innovative structural approach employed in building construction. It consists of reinforced concrete slabs supported by wide beams, called band beams, and narrow, parallel joists. This arrangement allows for loads to be primarily transferred in one direction to the supporting columns.

The band slab and joist system is particularly advantageous for structures with irregular or non-orthogonal column grids, accommodating unique architectural elements. While the increased floor height and complex formwork may present challenges, this system delivers a versatile and robust solution that adapts to diverse structural and design needs.

Dimensions & Sizes
Dimensions & Sizes

One-Way Band Slab & Joist Concrete Floors are constructed in a range of sizes with conventional spans between 10’-36’ (3.05-10.97 m) and post-tensioned spans of 18’-60’ (5.49-18.29 m). Slab depths are typically between 9”-25” (22.9-63.5 cm) based on the span to depth formula of Span/24. Column sizes for One-Way Band Slab & Joist Concrete Floors are commonly 12”-24” (30.5-61 cm) with pan widths of 20”-30” (51-76 cm) and pan depths of 6”-20” (15-51 cm).

Concrete floor systems are reinforced slab structures designed to satisfy a range of loading and span conditions in a building. Concrete floor systems are designed to span in either one direction (one-way) or both directions (two-way) of a structural bay.
