The calculated cracking width value which is presented in the table of results is the maximum value obtained from all the analyzed load cases. The Wood&Armer method is recommended for calculations of plates with cross reinforcement among others by EN:2004 AC:2008. Due to the implementation of NEN or Wood&Armer method, one may recognize the m xy moments in calculations by increasing the moments m xx and m yy. The analytical method for Serviceability Limit State does not recognize actions of m xy moments. ![]() Moments recognized in calculations of Serviceability Limit State are equivalent moments calculated according to the selected calculation method: analytical, NEN or Wood&Armer. Calculations are carried out on the cross-section with reinforcement resulting from the Ultimate Limit State (see: Reinforcement of plates and shells - calculations). The algorithm of calculations is based on the formulas enabling calculation of cracking width for beam elements. Implementation of the method not related to codes results from lack of relevant recommendations concerning plates with cross reinforcement. They are defined by axes of reinforcement and analogous to the simplified methods presented in relevant studies. The width of cracking is calculated independently for two directions.
