Explanation: Following assumptions have been made in IS 456:200 regarding maximum strain in compression members: 1) The maximum compressive strain in concrete in axial compression is taken as 0.002. 2) The maximum compressive strain at the highly compressed extreme fibre in concrete subjected to axial compression and bending and when there is no tension on the section shall be 0.0035 minus 0.75 times the strain at the least compressed extreme fibre.
