000009481 520__ $$2eng$$aA Displacement-Based Earthquake Loss Assessment (DBELA) methodology for urban areas, which compares the displacement capacity of the building stock with the displacement demand from earthquake scenarios, has been under development throughout the recent years. The building stock is modelled as a random population of building classes with varying geometrical and material properties through Monte Carlo simulation. The period of vibration of each building in the random population is calculated using a simplified equation based on the height of the building and building type, whilst the displacement capacity at different limit states is predicted using simple equations which are a function of the randomly simulated geometrical and material properties. The displacement capacity of each building is then compared to the displacement demand obtained from an over-damped displacement spectrum, using its period of vibration; the proportion of buildings which exceed each damage state can thus be estimated. The methodology has recently been further verified and calibrated by carrying out a number of structural analyses on case study buildings and frames from the existing European building stock, and in particular from Turkish buildings. Dual (frame-wall) buildings and reinforced concrete structures with infill walls have also been included in the methodology. The method has also been extended to include different types of Turkish masonry structures constructed with concrete and timber slabs. DBELA has been further calibrated to the Turkish building stock following the collection of a large database of structural characteristics of buildings from the northern Marmara Region. The probabilistic distributions for each of the structural characteristics (e.g. storey height, steel properties etc.) have been defined using the aforementioned database. Damage ratios relating cost of repair to cost of replacement for slight, moderate, extensive and complete damage for reinforced concrete buildings have also been obtained for the Turkish building stock. Preliminary results in terms of social losses for a single earthquake scenario close to the city of Istanbul are presented.
