It is found that Branson's expression is valid for members with steel... WebEngineering Civil Engineering 3.)A reinforced concrete beam 300 mm width has an effective depth of 450 mm. it is reinforced with 6-32mmØ at the tension side and 2-28 mmØ at the compression side located at 65 mm from the top. f= 34.5 MPa and fy = 345 MPa. Assume all steel yield and the contribution of compression steel may not be neglected.
