Two-Way Slab Punching Shear Example
Two-way slab punching shear check per ACI 318-19 §22.6. Computes critical perimeter b₀, size-effect factor λs, three vc limiting expressions for an interior column, and the design shear strength φVc.
Given Parameters
square interior column
slab thickness
average effective depth
concrete strength
factored column load
normalweight concrete
Calculation Steps
1. Critical Perimeter and Size-Effect Factor
2. Governing vc — Three Limiting Cases (Table 22.6.5.2)
3. Design Shear Strength
Demand / Capacity Ratio
