Basic value of allowable rotation θpl,d in plastic analysis
Eurocode 2 part 1-1: Design of concrete structures 5.6.3 (4)
Recommendation
The recommended values for the basic value of allowable rotation θpl,d for steel Classes B and C and concrete strength classes less than or equal to C50/60 and C90/105 are given in Figure 5.6N. The values for concrete strength classes C55/67 to C90/105 may be interpolated accordingly
