Abstract:

This study investigates the evolution and current status of seismic design regulations in Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela, using a pre-established methodology previously applied for Europe. It introduces a simplified methodology to estimate the proportion of buildings designed under four seismic code levels: no code, low code, moderate code, and high code. By analysing the progression of seismic design standards across South America, the study determines lateral force coefficients for a typical mid-rise reinforced concrete structure corresponding to each seismic code level. The findings reveal that approximately 20% of the total building stock, and 55% of reinforced concrete buildings, were constructed while regulations with some seismic provisions were followed. This research offers essential tools to enhance seismic risk assessment models and provides a dynamic framework for integrating new data, technological advancements, and local expertise into exposure modelling. Furthermore, it contributes to a global initiative led by the Global Earthquake Model (GEM) Foundation aimed at improving accessibility to information on seismic regulations and seismic hazard design demand maps.
