ƒ^ƒCƒgƒ‹i‰pjF TRANSLATING BUILDING VULNERABILITY FUNCTIONS BETWEEN REGIONS BY COMPARING BUILDING CODES
´˜^i‰pjF In this paper, a methodology is presented for translating earthquake vulnerability functions of buildings from region to region or era to era by systematically considering the differences in building design codes and construction practices. Two basic factors are considered: (1) difference in design base shear and (2) difference in ultimate deformation capacity of buildings in two regions or eras. The first factor controls the difference in structural behavior during elastic response. Its contribution is evaluated with a shift to the reference vulnerabil-ity curve. The second factor controls the difference in structural behavior from severe structural damage to collapse, and starting from the inelastic response point its contribution is evaluated through a rotation to the shifted reference curve. The translation of vulnerability curves for buildings in Portugal is taken as an example to demonstrate the application of the proposed method.
