EMPIRICAL TRANSFER FUNCTIONS TO BUILD SOIL CLASSIFICATION MAPS FOR SEISMIC DESIGN

摘要

Most important cities in Mexico lack geotechnical zonation maps as aids for seismic design. This paper proposes a methodology for combining those maps with spectral shapes obtained applying Nakamura's technique (HVNR) on microtremor records. The technique also uses the parameter VS, 30 and the code from The National Earthquake Hazard Reduction Program, NEHRP-2000. The technique was applied to the city of Puebla where five distinct spectral shape types were identified corresponding to an equal number of soil-type sites. Results validate the usefulness of VS, 30 as a parameter and also allowed for the construction of a zone map for foundation design.
