OTALVARO, IVÁN  e  NANCLARES, FRANCISCO. SEISMIC SITE RESPONSE EVALUATION FOR THE MEDELLíN ARAGÓN AREA. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.156, pp.147-155. ISSN 0012-7353.

This paper describes the results of site investigation and the site response numerical analyses for the Aragón area, located on the central eastern hillside of the Aburra valley, in Medellín. Site investigation as well as in-situ measurement of shear wave velocities obtained using down-hole techniques are presented. Residual soils produced by weathering of the San Diego Stock in a tropical environment are found at the site. The shaking ground profile for the synthetic earthquake developed by the Medellin Seismologic Group (2002).was modelled using one-dimensinal propagation waves model and the SHAKE91 computer program. The results presented might help in the design of structures that are planned to be constructed in the same geological body and for which the lithologic profile does not match the typical presented in the Medellin Seismic Microzonation. Additionally geotechnical engineers will find paths for dynamic behavior generated from samples which present different intensities of weathering. Such information might be useful for future analysis.

Palavras-chave : site effects; tropical soil; soil dynamics; down-hole.
