Learn More1. Determine the preliminary cross-section of b x h. We use EUROCODES 2 standard to choose b, h and a. Where : b is the width of the concrete h is the height of the concrete a is the distance from the edge of the concrete to the center of the steel bar. 'h' must be equal to ( 1÷8 ∼ 1÷220 ) L ; so we choose h = 350 mm.
