|---|---|---|---|
ACI 318-14 (2014) | \( V_{c} = 0.17\sqrt {f^{\prime}_{c} } b_{w} d \) | \( V_{s} = A_{v} f_{vy} d/s \) | 45° |
Eurocode 2 (2004) | – | \( V_{s} = A_{v} f_{vy} z/s \) | 21.8°–45.0° |
CSA A23.3 (2014) | \( V_{c} = \beta \sqrt {f^{\prime}_{c} } b_{w} z \) | \( V_{s} = A_{v} f_{vy} z\cot \theta /s \) | ≥ 29.0° |
