Punching shear resistance of a column base without shear reinforcement, vRd
Eurocode 2 part 1-1: Design of concrete structures 6.4.4 (2)
The punching resistance of column bases should be verified at control perimeters within 2d from the periphery of the column. The design punching shear resistance [MPa] of a column base without shear reinforcement may be calculated as follows:
|vRd = CRd,c k (100 ρl fck)1/3⋅2d/a ≥ (vmin⋅2d/a)||(6.50)|
- is the characteristic compressive strength of concrete, see Table 3.1
- = 1 + √200/d ≤ 2,0
where d is the effective depth, in [mm]
- is the distance from the periphery of the column to the control perimeter considered, in [mm]
- = (ρly⋅ρlz)1/2 ≤ 2%
ρly, ρlz are longitudinal reinforcement ratios in y- and z- directions respectively
- is a Nationally Determined Parameter, see § 6.4.4 (1)
- is a Nationally Determined Parameter, see § 6.4.4 (1), or (6.3N) for the calculation of vmin following the Eurocode recommendation.
This application calculates the punching shear resistance of a column base vRd from your inputs. Intermediate results will also be given.
