Crushing and flexural strength of slab–column joints

Mar 01, 2011· The crushing strength of the joint (N R) can be calculated as the sum of the compression strength of the concrete of the slab (N c, R) plus the strength of the reinforcing bars linking the upper and lower columns (N s, R see Fig. 1(a)).In the case where the eccentricity of the column load can be neglected it results in: (1) N R = N c, R + N s, R = f c c (A c − A s) + f y A s where

Sub-bases Pavingexpert

A 'slab' of mass concrete, usually 100mm or 150mm thick is spread and compacted, then allowed to set. A few days later (2-7 days, depending on time of year and weather conditions), the paving is laid on a bedding material over the now solid concrete. A medium strength concrete is used in most applications.
