摘要

A sizable portion of the current building stock in Bulgaria is of reinforced concrete structures that were constructed before the contemporary concepts for safe structural performance under earthquake action were implemented in the codes. The global characteristics of these aged building structures are identified alongside their conformance to the major typologies. The study provides a brief overview of the main strategies for enhancing performance and reducing the damage caused by strong earthquakes to these structures.
