A singly reinforced concrete beam has rectangular section 230 mm wide x 460 mm effective depth. At a section under consideration there are two 16 mm diameter bent-up bars at 45oand 6 mm diameter two legged stirrups at a spacing of 200 mm centre to centre. The grade of concrete is M20. The reinforcement is HYSD 415. The design shear strength of concrete is 0.6 N/mm2and maximum shear stress is 2.8 N/mm2. Using limit state method, determine the value of factored shear force to be permitted at the section.157.4

Answer» A singly reinforced concrete beam has rectangular section 230 mm wide x 460 mm effective depth. At a section under consideration there are two 16 mm diameter bent-up bars at $45^{o}$ and 6 mm diameter two legged stirrups at a spacing of 200 mm centre to centre. The grade of concrete is M20. The reinforcement is HYSD 415. The design shear strength of concrete is 0.6 N/mm $^{2}$ and maximum shear stress is 2.8 N/mm $^{2}$ . Using limit state method, determine the value of factored shear force to be permitted at the section. 157.4
