Analysis of 5 floor brick masonry builiding, type 77/5

Below we present the main results of the numerical analysis performed in ETABs, to assess the seismic response of an existing building, with brick masonry, type 77/5, which is part of many similar projects, built in the years 1975-1990, in Albania. While these 5-story buildings cover a significant percentage of residential buildings, the fundamental question is: "Are these buildings safe under seismic action, while so many families are accommodated on them? “This question stems from the following limitation: The 77/5 plan derives from regular forms, based on the recommendations of Eurocode 8.6 [4.2.3.2], p. 48. and KTP.N.2-89 (Technical Design Conditions), published by the Academy of Sciences. This study tends to answer this basic question.
