📍 Always consult a licensed structural engineer before attempting repairs on load-bearing beams.
Crack widths are controlled primarily by limiting reinforcement stress under service loads, using smaller‑diameter bars distributed over the tension zone, providing adequate concrete cover (but not excessive cover, which widens cracks), and ensuring proper stirrup spacing—particularly in shear‑critical regions, where excessive stirrup spacing is a common cause of diagonal cracking. : STRAP calculates the acting service bending moments
