Concrete Beam Shear Design Example
Step-by-step RC beam shear design example per ACI 318-19 §22.5. Calculates concrete contribution Vc, determines required stirrup spacing, checks maximum spacing limits, and verifies the demand-capacity ratio.
Given Parameters
web width
effective depth
concrete strength
stirrup yield strength
factored shear at d from support
normalweight concrete
Calculation Steps
1. Concrete Shear Strength Vc
2. Check Stirrup Requirement
3. Design Stirrups (Ø12, 2 legs, Av = 226 mm²)
4. Maximum Stirrup Spacing (governs)
5. Verify with s = 270 mm
Demand / Capacity Ratio
