Design strength for concrete struts in cracked compression zones: the value of ν'
Eurocode 2 part 1-1: Design of concrete structures 6.5.2 (2)
The design strength for concrete struts should be reduced in cracked compression zones and, unless a more rigorous approach is used, may be calculated from Expression (6.56) (see Figure 6.24).
|σRd,max = 0,6ν'fcd||(6.56)|
The recommended value of ν' for the calculation of the design strength for concrete struts is given by equation (6.57N).
|ν' = 1 - fck/250||(6.57N)|
