Análisis comparativo estructural y económico entre dos sistemas estructurales en edificios de hormigón armado de mediana altura ubicados en zonas de alto peligro sísmico.

Abstract

In this dissertation, a structural and economic comparison of the superstructure of a medium-height reinforced concrete building was carried out with two different structural systems, both resistant to seismic loads and located on an E-type soil in the city of Guayaquil. On one hand, the building with special moment resisting frames and on the other, the building with a combination of special walls and special moment resisting frames. Structural analyzes were performed only in the elastic range of materials through a program called ETABS (Extended Three-Dimensional Analysis of Building Systems). The designs of the reinforced concrete elements were executed considering the American code ACI 318-14 and the Ecuadorian Construction Standard of 2015 (NEC-15). Quantities and costs of the materials were obtained from the designs made and, with this information plus that obtained in the structural analysis, a comparison was made to conclude with the most suitable structural system in this investigation.
