EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 53 The mass and stiffness difference test relates to criterion (v) of section (a) of § 5.5.2 of the CEQS. The seismic wall shear test relates to criterion (vi) of section (a) of § 5.5.2 of the EIA. The relative movement controls between floors and nodes relate to criteria (iii) and (iv) of section (a) of § 5.5.2 of the EIS . The first check concerns the relative movement between floors (above and below) and the node check concerns the movement of each node of the floor, relative to the average movement of the floor to which it belongs. Both of these checks are done per direction. The control of idiosyncrasies relates to criterion (ii) of section (a) of § 5.5.2 of the CEQA. The tests of inadequacy indicators and morphological regularity relate to criterion (i) of section (a) of § 5.5.2 of the CEQA. The check of the indicator λ is carried out per level separately for beams and columns and the number of beams above or below 2.5 and the percentage of the total number of beams or columns in the building is indicated, at each level respectively. The totals below are the sums per structural element and in total. Finally, the morphological regularity test includes the criterion of the average λki deficiency index of each floor (§ 5.5.1.2(c) CEQA). OBSERVATIONS: The preliminary analysis scenario is used to calculate the criteria for selecting the type of analysis and gives an idea of the regularity of the building and the resistance of the building to earthquake. If, for example, there are λ>4 ratios for more than 30% of the building's elements, there is no point in further valuation of the building.
