8B. ANALYSIS PART 2

CHAPTER 8B 'ANALYSIS' 6 If the structure under inspection has B and STI quality materials, then in the definition of materials, in the sizing parameters, and before the initial sizing, you must define and modify the parameters of the materials per structural element by adapting them to the characteristics of the new materials and modifying the strengths accordingly, based on the of the CEE. • EXISTING MATERIALS The CEE prescribes individual safety factors γm (γc and γs for concrete and steel respectively) which for existing materials are differentiated if the check is performed in terms of forces and if it is performed in terms of deformations and depend on the data reliability level (CEE § 4.5.3.) ✓ for the Elastic analyses (checks in terms of forces - intensive) the representative (characteristic) strength value of materials is: the average value minus one standard deviation , while ✓ for the Anelastic analyses (checks in terms of deformation) and for the m method, the representative (characteristic) strength value of the materials is average price . (Method m is considered be one of the inelastic methods for the determination of strength). 3 h revision of the EIA CIP The 3 th revision of the EIA brings changes that also have to do with the Data Reliability Levels. To be more precise, and until now there were individual SDSs. More specifically there was: - Material SDS that affected the Resistances (Strengths). It is distinguished into SADIS (Concrete) and SADYX (Steel). In the program there was in the definition of material strength in the dimensioning. - Geometric data of the structure based on the following table. The table that existed until now and is related to geometry and reinforcements. The geometric data affect the actions. In the program, it is the option in the analysis scenario and affects the coefficient of permanent loads γg. With the 3 h revision of the EIA CIP • The SDS relating to geometry was named SDG with two subcategories SDG1 and SDG2 and the SDS relating to the layout and reinforcement clamping details was named SDL . • Until now, only the material's SWD was taken into account for the determination of strengths. In the new revision for the determination of the strength of steel in terms of forces is very logically taken into account and the SADL . Thus the coefficients affecting the strengths of the materials are as follows:
