Description
Description

A two-way concrete waffle slab is a structural system utilized in building construction, characterized by a grid-like arrangement of ribs or joists that form a waffle-like pattern. This reinforced concrete slab spans in both directions, distributing loads to supporting columns.

The waffle slab design offers increased load-bearing capacity, stiffness, and reduced self-weight compared to conventional flat slabs, making it suitable for large-span applications like commercial or industrial buildings. Moreover, the waffle slab's aesthetic appeal can enhance architectural designs. However, its complex formwork and longer construction times may result in higher costs, and it can also limit the flexibility of ceiling and mechanical systems installations.

Dimensions & Sizes
Dimensions & Sizes

Two-Way Waffle Slab Concrete Floors are constructed in a range of sizes with conventional spans between 25’-55’ (7.62-16.77 m) and post-tensioned spans of 30’-80’ (9.14-24.38 m). Slab depths are typically between 10”-29” (25.4-73.7 cm) based on the span to depth formula of Span/24. Column sizes for Two-Way Waffle Slab Concrete Floors are commonly 24”-40” (61-101.6 cm) with dome widths of 19”, 30” (48, 76 cm) and dome depths of 8”-20” (20-51 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.
