According to TBDY 15.2.5 , the level of knowledge obtained from the buildings for which the performance analysis will be made is taken as the comprehensive knowledge level, and the knowledge level coefficient is taken as 1.00. Information level coefficients are used to calculate the capacity of reinforced concrete members in the performance analysis (linear or non-linear) of existing buildings.


  • The knowledge level coefficient is determined by the user.

  • The reinforcement corrosion coefficient and insufficient clamping length yield stress coefficient are determined by the user.

  • Material definition and material strengths are entered by the user.

  • After selecting the material definition, information level coefficient, reinforcement corrosion and clamping length yield stress coefficient, section capacities and limit values ​​are automatically calculated.


 Comprehensive level of knowledge is explained in TBDY 15.2.5 .

The figure below shows from which section the reinforcement corrosion factor and insufficient clamping length yield stress factor values ​​are defined.
