Crushing and flexural strength of slabcolumn 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 1aIn 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 f c c
