Seismic Performance of the Existing and Newly Designed Wall Buildings

Buildings with reinforced conrete structural walls are frequently used in Croatia. Wall-to-floor ratio (at least in one direction) is usually high and although these walls were typically lightly reinforced with simple reinforcement details, such structures exhibited well behavior during previous earthquakes. Nevertheless, their analysis is usually quite complicated and time consuming at which end we find out that following minimum requirements were enough in the first place. The basic goal of this research was to simplify design and evaluation of structural wall buildings by introducing "Performance domain" method as well as by the nonlinear static method N2. Evaluation is performed on a chosen sample of wall buildings designed following minimun requirements according to the old HRN codes (for existing buildings) and new seismic codes.
