A concrete column section of size 300 mm × 500 mm is subjected to both axial compression and bending along the major axis. The depth of the neutral axis (xu) is 1.1 times the depth of the column (D = 500 mm). According to IS 456:2000, the maximum compressive strain (εc) at the highly compressed extreme fiber in concrete, where there is no tension in the section, is given by 0.0035 - 0.75εmin, where εmin is the strain at the least compressed fiber. The maximum compressive strain (εc) × 10-3 (rounded off to 2 decimal places) is:
