Description
Description

A one-way concrete joist slab, employed in building construction, is a structural system featuring a reinforced concrete slab supported by parallel, slender joists. This configuration directs load transfer predominantly in a single direction toward the columns. One-way joist slabs are advantageous for spanning moderate distances while maintaining structural efficiency and reducing material usage.

They are well-suited for structures where consistent, parallel load paths exist, such as residential or low-rise commercial buildings. Although the system's floor height and formwork may pose challenges, one-way concrete joist slabs provide an effective and economical solution that caters to specific architectural and structural demands.

Dimensions & Sizes
Dimensions & Sizes

One-Way Joist Slab Concrete Floors are constructed in a range of sizes with conventional spans between 10’-40’ (3.05-12.19 m) and post-tensioned spans of 27’-80’ (8.23-24.38 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 Joist Slab Concrete Floors are commonly 12”-30” (30.5-76.2 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.
