Perform cracked section analysis for checking the cracking deflection in meshed slabs as per Eurocode2:04.
Note 1 Cracked section analysis is carried out in the post-processing mode after completing elastic analysis.
Note 2 Cracked section analysis is carried out when the load combinations are selected in Deflection (Cracked) field in Slab Wall Load Combinations. Quasi-permanent type serviceability load combination can be selected in Deflection (Cracked) field. Serviceability load combination type can be classified in Serviceability Load Combination Type into Characteristic, Frequent, or Quasi-permanent.
Note 3 How to calculate the effective moment of inertia
Cracking deflection can be checked in Slab Serviceability Checking. Members which are expected to crack, but may not be fully cracked, will behave in a manner intermediate between the uncracked and fully cracked conditions and, for members subjected mainly to flexure, an adequate prediction of behavior is given by the following expression based on the sub clause 7.4.3 (3) in EN 1992-1-1:2004. Following factors including the effective moment of inertia by elements for each iteration step can be checked in "File Name_CSA.OUT" file.
Therefore Ieff (effective moment of inertia) can be calculated from the following equation.
