Análisis de interacción suelo-estructura mediante un ensayo de pórtico a escala en una mesa vibratoria considerando un suelo típico de Quito

Abstract

This work is of an experimental-theoretical nature where first, the computational model of a simplified and reduced structure without soil was calibrated to later leave the soil as the only variable in subsequent tests, modifying the stiffness coefficients obtained by ASCE 41-17. The experimental test was performed using digital image correlation (DIC) and accelerometers, thus obtaining the lateral displacements of each floor. This is compared with the computational model already calibrated, successfully achieving the expected results since, for all the methods, there is an amplification of more than 300% in loose soil drifts in relation to a recessed structure, thus confirming the importance of considering the interaction floor structure in any engineering work deposited on soft soil.
