Análisis comparativo técnico del comportamiento de muros cortos agregando postensado aplicado a viviendas con otros sistemas estructurales.-

Abstract

Considering that in Ecuador, unlike other countries which have equal or greater seismic danger, such as Chile. It is usual the design of the lateral resisting seismic force system using special moment frames however, this system has not given adequate seismic-resistant results in extreme situations such as the presence of a large earthquake. The importance of design alternatives is necessary. This study compares three different lateral force resisting systems with squad shear walls in four-story house using Reinforced concrete squad shear walls, post tensioned concrete shear walls and Mesh Reinforced Masonry. Using a software package from CSI Structures, ETABS 2018, the finite element method is analyzed, this method is compared with method proposed by ACI 318-19 using EXCEL spreadsheets for the development and comparison of iteration diagrams; methods in which acting vertical loads are specified and seismic-resistant calculations such as floor drifts and vibration modes are performed. In addition to the structural study, a comparative cost analysis is performed for each of the systems; a study that allows determining that the most recommended systems are the reinforced concrete shear walls and post-tensioned concrete shearwalls because they have shown more economical results.
