A doubly Reinforced beam of cross-section 400 mm × 600 mm is provided with compression and tension reinforcement as shown in figure below. Calculate the value of strain at location of compression steel. Use M-25 Grade of Concrete and Fe-500 Steel. Take fsc = 0.87fy of Concrete and Fe-500 Steel. Use fsc = 0.87fy
