Evaluación de la amenaza sísmica de Colombia. Actualización y uso en las nuevas normas colombianas de diseño sismo resistente NSR-10

Abstract

The use of more refined models and computational techniques for seismic hazard evaluation and the availability of more data related to seismic events have allowed the updating of national seismic hazard studies. This paper summarizes the new methodology used to estimate the expected seismic intensities for design and construction of earthquake resistant structures in the country. Seismic intensities are obtained for different return periods and spectral ordinates, for the different heights of buildings. This data is useful in establishing design values in the new national building code NSR-10 and for the development of seismic microzonation studies. (English) [ABSTRACT FROM AUTHOR]
