A simply supported beam with span of L = 5.4 m must be designed to support a uniformly distributed total dead load of 15 kN/m and live load of 9 kN/m. Using material strengths fc = 21 MPa and fy = 420 MPa, consider b=0.55d, calculate the required effective depth in mm if the tensile steel strain compatible with concrete strain of 0.003 is set at 0.013. Express your answer in two decimal places.
