Project Sub-Title : First Floor Slab Made by Date Sketch and Plan Sketch on Hollow Pot Slab Plan Slab Dimensions Hollow pot slab width, b = 3.00 m Hollow Block Dimensions & Thickness of Topping Hollow blocks have same length (L=457mm) and width (W=205mm) but their heights , H varies. Hollow blocks have a minimum crushing strength of 3.50N/mm2 ...
Structural Design of Ribbed Slabs - Structville
Mar 7, 2020 · A ribbed slab is a type of reinforced concrete slab in which some of the volume of concrete in the tension zone is removed and replaced with hollow blocks or left as voids. This reduction in the volume of concrete in the tension zone (below the neutral axis) is based on the assumption that the tensile strength of concrete is zero, hence all the ...

Key details include: - The slab spans 5m x 7m with ribs running in the shorter direction - Design assumptions include a C25 concrete, 12mm diameter bottom reinforcement bars, and a total factored load of 6.26kN/m - Shear and moment calculations are shown - Two 12mm diameter bars are designed as the bottom reinforcement over the midspan - Shear ...
Compared to the one way spanning ribbed slab system, the hollow pots system is limited to have a clear rib span of ~450mm which is the width of a hollow block.
Hollow Pot Slabs Design
This document summarizes the design calculations for the hollow pot (waffle) continuous slab of a dormitory building with 6 spans of 10m x 8m. Key details include: 1) The slab has a 75mm thick topping and 125mm wide ribs spaced at 0.45m. 2) Design loads considered are a 2.37 kN/m^2 dead load and 5 kN/m^2 imposed live load.
