Detailed Structural Characterization of Existing RC Buildings for Seismic Exposure Modelling of the Lisbon Area

As many European countries, the Portuguese territory is a region of moderate seismicity, and large part its building stock includes reinforced concrete (RC) buildings built before introduction modern seismic codes (<1983s). Currently, Lisbon composed 45% RC buildings, which 71% were in such construction period. Being designed to only sustain gravitational loads without adequate lateral load resistance, these are likely be severely damaged during an earthquake. This highlights need propose reliable risk assessment earthquake loss models for structures. In this context, development exposure model quantifies susceptible seismically damaged, terms structural characteristics, spatial location, occupancy, major importance. The main purpose paper contribute definition city Lisbon, focusing on detailed characterization typologies. It starts with extensive collection analysis design blueprints existing two Lisbon’s neighborhoods: Alvalade Benfica, found representative city. Then, information collected scrutinized statistically post-processed through probability distributions that provide clear insight typologies their characteristics. These results can used future numerical derive fragility vulnerability models, fundamental conducting analyses.
