EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 6 Assessment and redesign objectives §2.2 The assessment or redesign objectives (Fig. 2.1) are combinations of a Performance Level on the one hand and a Seismic Action on the other hand, given a "tolerable probability of exceedance during the technical lifetime of the building" (design earthquake). In the EIA CIP, reinspection targets are provided for, referring only to the load-bearing structure and wall fillings. The choice of a specific valuation or redesign target implies the use of appropriately modified q or m indices, or tolerable deformations δd, the values of which are specified in Chap. 4 and 9. It should be noted that the objectives of evaluation and redesign are not necessarily the same. Redesign targets may be higher than valuation targets. Table 2.1 shows the correlation between the performance level of the load-bearing structure and the corresponding reduced horizontal ground acceleration.
