A dynamic response model for soft soils has been developed for Bogota through the application of a modern methodology which is based on the geometry of the geologic formations.For the assessment a tridimensional geometric model of the city’s sub-soil is constructed based on the geologic interpretation of the formations present, defining the elevation (above sea level) of the geological contacts. Available geotechnical information is used to assign types of soil to the geometric model. The static and dynamic properties of the soils are defined as random variables and their probability moments are calculated through statistics performed over the available geotechnical data. The dynamic response is calculated for each point of a grid defined for the city, through a process that allows for the definition of strong motion attenuation functions, which include the uncertainty associated with the site response, specific for each grid point. Finally, seismic hazard is calculated at ground level and uniform hazard spectra are obtained for a return period of 475 years. This soil response model was employed in a seismic risk evaluation performed for Bogot\u00e1, as well as in the construction of the automatic post-earthquake damage evaluation system for Bogota, LISA. \u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
