Tips for Designing RCC Concrete Beams
Some commonly used beam widths are 200, 230 and 300 for practical, structural and aesthetic reasons. Depth of the plinth beams can be inferred from the length of the span. Use the formula span/15 to span/18 to get the depth of the plinth beam. For Tie beams, assume overall depth from the span/18 to span/20.…
