Estudio de los efectos de interacción suelo estructura en cimentaciones superficiales de edificaciones

Abstract

This paper presents an analysis of the effects of dynamic interaction of soil structure on surface foundations of buildings in the seismic design of structures by means of response spectra in relation to the seismic source and deposits of soils with respect to the implanted structures. The main effects of the dynamic interaction floor structure are the addition of flexibility and damping to the structure through its foundation. The importance of the meticulous study of soil structure interaction is reviewed by modern displacement-based methods such as the Direct Design-Based Displacement method, evaluating its ability to consider the effects of soil structure interaction. The interaction effects on the required resistances for inelastic systems, including kinematic interaction and inertia, are evaluated. The effects of interaction in the period and damping of the fundamental mode of vibration, as well as structural ductility, are considered. The simplified models used to stipulate the design criteria are described. Finally, as a conclusion, the difference between buildings with superficial foundation is presented, one without interaction and another that if it contemplates this one, showing the importance and relevance of its consideration in the structural designs
