EXAMPLE 6. BUILDING VALUATION & REDESIGN STUDY

EXAMPLE 6: "STUDY FOR THE VALUATION AND REDESIGN OF A BUILDING ACCORDING TO THE CANC. 73 In buildings designed and/or constructed before 26/02/1959 as well as in buildings without a building permit, either partially or in their entirety, the seismic load factor e will be considered as the factor that should have been taken into account according to the Seismic Regulation of 1959, depending on the seismicity of the area (I, II, III) and the risk of the ground (a, b, c). In case of application of non-linear methods of analysis, as provided for in the C.E.P.E., a horizontal elastic acceleration spectrum Se (T) shall be used, which shall be derived from the above-mentioned horizontal design spectrum Sd (T) (Figure 2 and Table 3) by setting k= to 1.0 and multiplying the values of the squares of the Sd (T) spectrum by a factor of 1.50 for buildings of the period ...< 1985 and by a factor of 2.00 for buildings of the period 1985 < ... < 1995, respectively. For this reason, non-linear analysis methods are applied, check the checkbox on pre-1985 buildings.
