== Abstract ==

The present study case highlights the importance of considering local failures for
irregular unreinforced masonry buildings, by means of nonlinear seismic analyses. Simplified
seismic assessments based on equivalent frame method were used in order to capture the
structural behavior of the National Geological Museum from Bucharest in its initial form and
also the current structural layout.
The retrofitting works realized in the 1982 were focused on strengthening the transversal
masonry walls and on creating horizontal diaphragms to improve the “box behavior” of the
building subjected to lateral forces. Retrofitting of unreinforced masonry walls by reinforced
concrete jacketing and the replacement of flexible floors by reinforced concrete slabs were
previously considered to be effective only though post-earthquake visual inspections of the
strengthened elements. The efficiency of past interventions is studied in the present paper
through comparisons between the two models in terms of damage patterns, global behavior and
also performance levels established function of maximum relative displacements.
