Punching shear resistance of a lightweight concrete slab without shear reinforcement: the value of k2
Eurocode 2 part 1-1: Design of concrete structures 11.6.4.1 (1)
The punching shear resistance [MPa] of a lightweight concrete slab may be calculated as follows:
| vlRd,c = ClRd,c k η1(100 ρl flck)1/3 + k2 σcp ≥ (η1 vl,min + k2 σcp) | (11.6.47) |
Recommendation
The recommended value of k2 is 0,08.
