Punching shear resistance of a lightweight concrete slab without shear reinforcement: the value of k2
Eurocode 2 part 1-1: Design of concrete structures 188.8.131.52 (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)|
The recommended value of k2 is 0,08.
