Overview
Seismic risk Scope of the Marie Curie ERG Differences / common characteristics Romanian, Greek, Italian Modernism Zoning illustrations Modern – vernacular Conclusions
Seismic risk
Bucharest Earthquakes 1940, 1977 1977 interwar buildings proved most
vulnerable
Scope of the Marie Curie ERG
Marie Curie European Reintegration Grant 2007-2010 Zoning in blocks of flats Bucharest, Romania Athens, Greece Milan, Italy (Budapest, Hungary)
Differences
Earthquakes
Bucharest 1940, 1977 Athens 1999 Milan never Budapest never
Common characteristics
Historic Reinforced Concrete Luxury dwellings, unlike in Western
Europe (social housing) No seismic codes Zoning – the way of living led to an
architectural shape which rendered vulnerable
CA’REDIVIVUS (prior project)
Romanian Modernism
Irregular shape in plan and section 4 EWICS Lack of seismic culture Vrancea earthquakes did not affect
traditional low rise housing buildings Typology from France Calculation tables from Germany
Romania
Earthquakes affected slender buildings like churches
Local seismic culture developed there Modernist buildings in the city centre from
retracing of streets < irregular parcels

Modernism - vernacular
Modernism negated historic links Similarities independent from location
(universal style) Change from single family to multi family
housing Study on vernacular and modernist in
Germany http://www.world-housing.net Traditional is modern

Conclusions
In Romania buildings are most vulnerable due to high irregularity
The irregularity resulted from the architectural adaptation to the form of the parcels given the urban interventions following the CIAM
