Steps for Designing Beams

A structured approach to beam design per NDS 2024 ASD.

Design Steps

1. Determine loads – Dead load, live load, and applicable load combinations.
2. Compute reactions and moment – Shear and moment diagrams.
3. Check bending – F'b = F_b × C_D × C_M × C_t × C_F × C_r × C_i; M ≤ F'b × S.
4. Check shear – f_v ≤ F'_v (adjusted shear design value).
5. Check deflection – Δ ≤ L/360 (or project limit).
6. Check bearing – F'_c⊥ at supports.
