Análisis tiempo-historia de edificios aporticados y duales de mediana altura ubicados sobre suelos blandos en la ciudad de Machala

Abstract

The purpose of this degree work is to perform a dynamic time-history analysis of reinforced concrete and structural steel structures, taking into account the study area of the city of Machala and the presence of soft soils. For seismic demand characterization, a collection of thirteen accelerographic spectro-compatible records with the acceleration design spectrum established in the Norma Ecuatoriana de la Construcción was used, for a return period of 475 years. The records used belong to the seismic events occurred on March 18, 2023 and April 16, 2016 in Ecuador, as well as events occurred in Chile on February 27, 2010 and April 1, 2014. The evaluation of the dynamic response of the structures was carried out based on floor drifts, displacements and forces, as well as guidelines established in the Norma Ecuatoriana de la Construcción, ASCE and HAZUS99.
