EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 13 Finally, the safety inequality is checked by what is mentioned in more detail in Chap. 9, depending on the level of performance (see Chapter 2 of the CEFR). Individual safety factors §4.5 Depending on the reliability of the data: i. Appropriate safety factors γf are selected for certain actions with uncertain values, in combination with appropriate γSd (see § 4.4 and 4.5). ii. Appropriate safety factors γm are selected for the existing material data, in combination with appropriate γRd (see § 4.4 and 4.5). For the Simulators § 4.5.1 For the analysis simulations and for all tests, appropriate values of the individual safety factors γSd and γRd are used in order to take into account the increased uncertainties that accompany them. The coefficients γRd are obtained in accordance with the provisions of Chapters 6 to 9 of the EIA. The csd coefficients are obtained according to the severity and extent of the damage and deterioration suffered by the structure under study and are presented in Table C4.2 of CEE: Also, according to Chap. 5, and as far as elastic analysis, static or dynamic, is concerned, its application is permitted, for valuation purposes only, irrespective of the validity of the application conditions (see §§ 5.5.2.b and 5.6.1.b), if the γSd factors in this § 4.5.1 are increased by 0.15 (i.e. γSd,el. = γSd + 0.15). Analysis The determination of the building's stresses and strains requires the analysis of the building for the combinations of actions defined in § 4.4.2. Based on the stresses and strains resulting from the analysis by one of the recommended methods (§ 5.1.1), the corresponding checks for the satisfaction of the performance criteria, as described in §§5.1.3 and 5.1.4, as well as in Chap. 9. The methods that can be used for the analysis are: - Elastic (equivalent) static analysis (see §5.5), with global behaviour index (q) or local index (m) - Elastic dynamic analysis (see §5.6) with global behaviour index (q) or local index (m) - Elastic static analysis (see §5.7) - Inelastic dynamic analysis (time history analysis) (see §5.8).
