How can calculate the rcc beam depth according to the span?

To calculate the depth of a reinforced concrete (RCC) beam based on its span, you can use the empirical formula: depth (d) = span length (L) / 12 to 16, depending on the loading conditions and beam type. For simply supported beams, a general rule of thumb is to use L/12 for lightly loaded beams and L/16 for heavily loaded ones. Always consider factors such as the material properties, loading conditions, and any applicable building codes for a more accurate design.
