Study of Dynamic Behavior for Soil in University City Puebla, Pue. Mexico.

Abstract eng:
As information necessary for the seismic design of structures in University City (UC) of the Autonomous University of Puebla (BUAP), a study in its first stage was to determine the dynamic characteristics of soil. Thus contributing more to safer designs of all buildings in UC. At this stage only the ambient vibration recorded with sensors broadband speed CMG Guralp 40T connected to K2 Kinemetrics equipment, processed using the technique of spectral ratios H/V. In this second stage, again it uses the technique of spectral ratios H/V, but this time acelerometric data processing records from a seismic station for period’s dominant soil, also new ambient noise register with Guralp equipment installed in a temporary network arrangements. The network consists of 16 triaxial accelerometers Guralp broadband 6TD CMG-time synchronized recorded ambient vibration simultaneously, and then the information processed by SPAC method to determine the shear wave velocity. As result of analysis of data obtained in two stages and supported by testing direct geotechnical exploration, a correlation with which the dynamic properties of soils verified in order to perform mappings that can used to estimate spectra obtained site, same that will used for the construction of future buildings with more efficient seismic designs.
