  • Abstract in English : In the frame of the Collaborative Research Centre SFB461 “Strong Earthquakes” a study on a part of the centre of Bucharest was done. This part comprises a section of the N-S Boulevard which is most characteristic for the development of the Modern Movement in Romania: most of the blocks of flats along the street were built in 1920-1940. The study included a survey of the building stock, but also of the street structure. In case a strong earthquake would strike Bucharest, and an emergency would occur, it is necessary to plan the evacuation of the zone. Emergency routes can be included in urban planning. They should lead to a so-called security centre, where emergency housing can be built. The challenge in planning such routes is that the streets might become blocked by rubble. For this reason the surveyed data included the width of the street reported to its fronts. The data were introduced in a GIS database, and attempts to convert the data in 3D were done. The urban frame of a street is defined by its floor, background and fronts. Analytically, the analysis of this frame begins with that of its profiles and parcours. A further step is the historic study. An essential element of the Master Plan of Bucharest 1935 was the circulation network. Circulation control was expressed in the shape of street fronts, for which concepts of style were included. For the centre, the cornice height limit was fixed, except at corners, leading to set-back upper floors. Apart of rubble, also short term earthquake countermeasures such as propping may affect the functionality of the road network. Such issues should be considered in the further model, additionally to the immediate emergency management. The paper thus reviews the approaches so far and give recommendations for the usability of a 3D model considering street network functionality issues in case that an earthquake strikes.
