Estudio del comportamiento sísmico de la interacción suelo-cimentación en una estructura metálica representativa

Abstract

Ecuador is located in an area of high seismic hazard, mountainous terrain, slopes of low, medium and high slopes in the Sierra region mainly, the high housing deficit and without considering the danger of founding the structures in this type of soil, the human being makes disorderly settlements and without any planning and control by government entities, This is why it is necessary to carry out a comprehensive technical analysis to determine the favorable response of the building to a dynamic event in a sloping terrain. The factors involved in the dynamic soil-structure interaction were analyzed, such as accelerations, velocities, displacements, the relationship between them and the variations in the fundamental period of the structure when considering the flexibility of the foundation soil; For which through the use of springs and dampers (impedance functions) that represent the dynamic response of the IDSE system based on the Barkan model and the NEC-15, the increase of the flexibility in the foundation base of the soil-structure interaction model, with respect to the rigid base model in a type D soil, was determined by means of dynamic and experimental simulation. As a consequence of the present research work, a notorious change in the behavior of the foundation of the structure was obtained, which was subjected to the load solicitations initially proposed and related to the traditional rigid base model. The results of the present study can be used to improve design and construction techniques, in addition to providing relevant information to professionals in the engineering field on the soilfoundation interaction of structures. In order to extend the analysis of the aforementioned conditions, an analysis of the soil-structure behavior can be included in future research.
