Evaluación del efecto interacción suelo - estructura en edificaciones con cimentación profunda.

Abstract

The following work deals with the evaluation of the soil-structure interaction effect in prototy of building with deep foundations, considering in the foreground an analysis with a rigid base and another with the soil-structure interaction effect (ISE), to evaluate parametrically the importance of considering the soil-structure interaction effect when performing the dynamic analysis of the structure. Observing the international regulations and guide FEMA P – 2091 and ASCE/SEI 7-22. In high seismic risk areas such as Machala, the behavior of the structure is affected by three factors: the soil, the foundation, and the structure itself. This is why analysis with a rigid base is not convenient; soil-structure interaction (SSI) is a crucial aspect to consider in seismic design since it can have both a positive and negative impact on the response of buildings. In some cases, ISE can increase the strength of the structure by providing a longer period of vibration and damping, but it can also increase seismic forces and other structural demands in soft soils. This work includes the analysis of the flexibility in the substructure of the prototype proposed in the city of Machala, modeled with the help of the commercial structural analysis software. Under these results, the displacements, vibration periods, stresses, deformations, vibration modes, and all changes are given in the structure
