The study of seismic vulnerability of residential buildings in Ulaanbaatar has been performed for 14 typical objects. Those included old brick houses, 5- and 9-story large-panel houses, and new 8-16-story frame buildings. Classification of buildings by seismic resistance has been conducted on the new Russian scale GOST R (project). Engineering-seismometric studies have been made on dynamic characteristics of buildings at microseisms. Seismic risk assessment has been made for housing and population of Ulaanbaatar.
