Extracted text: The cross-section of the reinforced concrete beam having an effective depth of 500 mm is shown in the figure (not drawn to the scale). The grades of concrete and steel used are M35 and Fe550, respectively. The area of tension reinforcement is 400 mm?. It is given that the corresponding to 0.2% proof stress, the material safety factor is 1.15 and the yield strain of Fe550 steel is 0.0044. 500 mm 100 mm 200 mm 0 A, = 400 mm? As per IS 456:2000, the limiting depth (in mm, round off to nearest integer) of the neutral axis measured from the extreme compression fiber, is ww 00
