9.1.4 Curvature for Cracked Sections (State II)
Curvature for Cracked Sections (State II)
Curvature due to loading
When characteristic loads are applied, concrete shows linear elastic behavior.
The concrete stress distributed over the compression zone is assumed to be triangular.
The depth of the concrete compression area can be determined as follows:
The tension stress in the reinforcement is determined with MEd = 18.50 kNm as follows:
The curvature in the final crack state is determined as follows:
Curvature due to shrinkage
In manual calculations, the curvature for cracked sections (state II) is determined by means of a table from  (see Figure 9.2).
