Geotechnical zonation and soil–structure interaction at Puerto Vallarta, México

We performed a seismic vulnerability assessment that involves geotechnical and building structure analysis for Puerto Vallarta, Mexico, city located along the pacific coast. like many other Latin American cities, has significant risk. implemented multichannel of surface waves horizontal-to-vertical spectral ratio methods to estimate shear wave velocity soil resonance frequency. considered standard penetration test determine resistance classification. divided Vallarta into four zones according taxonomy based on construction materials structural systems story number height. The VS30 parameter shows types C, D, E National Earthquake Hazard Reduction Program (NEHRP). classified three estimated fundamental period, TS. Both TS parameters showed an overall transition properties from mountain toward valley area. tests corroborate results geophysical methods. correlation between period most common at each zone indicates high vulnerability. identify effects principally south coast Vallarta. This work combines academic governmental efforts solve real transcendental problem since it might directly affect regulation evaluations structures in
