Comparación de dos programas en el análisis de respuesta de sitio en depósitos con suelos blandos.

Abstract

Ecuador is located within the countries that are settle on the belt of fire, named in this way because this area where most of the seismic activity in the world occurs. Historical data have shown that there are changes in seismic signals due to the varied characteristics of soil deposits. To evaluate this effect it is necessary to perform a site response analysis in order to capture the true magnitude of accelerations that will affect the surface. Guayaquil is a city where large deposits of soft soils abound whose influence amplifies the accelerations considerably. There are different methods to analyze the dynamic response of the soil during a seismic movement. In this research a dynamic response analysis will be carried out in two different programs (DeepsoilV7 - PLAXIS 2D) for a specific site. For the resolution of the models made in each program, different methodologies were used. Linear equivalent and non-linear for DeepsoilV7 and finite element software for 2D PLAXIS. With the results obtained, comparisons were made of each of the methodologies and the different parameters that both programs consider to execute the same analysis and obtain each of their results.
