Evaluation of the Seismic Behaviour of a Building for Residential Use Based on a Typical Soil and Implementing the Ecuadorian NEC-SE-DS Standard

Abstract:

The present work allows evaluating the behaviour of a building in the city of Guayaquil built on a soft soil type E, considering the seismic performance based on the last earthquake that hit Ecuador and left irreparable damages. For this reason, the structure was modelled for further analysis using structural analysis software (ETABS) to evaluate and compare the values collected from the measurement in the accelerograph of Guayaquil and Manta, and thus have a reference and knowledge regarding the damage, displacements and deformations presented. The objectives of this work are to demonstrate the behaviour of the structure, analysing the static level of the infrastructure placed in pseudo-dynamic and dynamic time-history mode; where a redesign of the structure is considered, considering the current regulations regarding stability, drifts, and shear forces. The work provides and expands the data on factors that increase the seismic hazard, which in the future can be contrasted with similar studies within the city of Guayaquil, to analyze the possible variants of how to improve future constructions.
