    Variación de las derivas en edificaciones por efectos dinámicos de interacción suelo-estructura
    (Universidad EAFIT, 2018) Bello Mena, Kevin Jushep; Botero Palacio, Juan Carlos
    The interaction soil-structure effects (ISS) produce variations in dynamics behavior on structures, those variations are product of soil’s flexibility. A conventional procedure ISS has been made, and it was obtained that when the vibration period increases the seismic forces decrease; and hence, the drift generated by those forces. Nevertheless, the lateral displacement increases because the rotation in the structure base, generating displacements of rigid body, those displacements do not produce damage in structural members. In this way, the drift will increase if in the calculation of those is include the rigid body displacement, and the drifts will decrease if this rigid body displacement is not including in de calculation of the drifts. In addition, it was founded that the basal shear decreases up to a 60% by ISS effects. It was also found that the maximum decrease in the drifts because the ISS effects is 81.52%.
