QUANTITATIVE RISK ASSESSMENT METHODOLOGY FOR BUILDING SELECTION IN RETROFITTING PROCESS

Abstract : Since 2011 French territory has a new seismic zoning including five seismicity areas (very low to high), from which acceleration (PGA) is referring to the design of new buildings with standards Eurocode 8. However seismic regulations apply to existing buildings, often built before its application, only for specific work conditions. With an annual turnover about 2%, the knowledge of existing buildings compliance with seismic design is capital for seismic risk management policy. In this context, the working group of French Association for Earthquake Engineering (AFPS) was interested in defining a quantitative evaluation method of seismic risk and compliance of existing buildings. The proposed methodology considered a large building number application with only basic vulnerability information. The main goal is obtain a large picture for decision making based on risk criteria with identification in a first step high risk buildings and in a second step compliance to seismic standards. This communication presents the general procedure of methodology for risk evaluation steps and compliance standards of existing buildings. Application of methodology to French seismic context is shown through different examples.
