PRUEBAS DE VIBRACIÓN AMBIENTAL PARA DETERMINAR LAS PROPIEDADES DINÁMICAS DE UN EDIFICIO DE 23 NIVELES Y LOS EFECTOS INTERACCIÓN SUELO-ESTRUCTURA.

Abstract

In this work is presented the experimental resolution of the main dynamic properties and the soil-structure interaction effects (ISE effects) of a building of 23 levels. This building is part of a set located at a soft soil zone in Mexico City. The analysis was made with information obtained in a test of ambiental vibration made on the structure. The methodology used to determine the dynamic properties is based in a nonparametric method of estimation. This consists on to making a conventional spectral analysis of signs captured at the different tool points on the soil and structure. By this analysis are also obtained the structure’s vibration frequencies. To determine the ISE effects is used the Dyna5 program and the method proposed by RCDF (2004) in its appendix A.
