Estudio y propuesta de factibilidad técnica y económica del sistema constructivo denominado Mampostería Reforzada Alivianada (MRA), para vivienda de interés social en Ecuador

Abstract

This research presents an innovative blocks made of expanded polystyrene that are placed in a structure. There are leaning ducts in both directions of the interior of this structure, these ducts are filled with micro-concrete of high plasticity and reinforcing steel that converges with the steel of the adjoining elements. Previously we built some walls for axial and diagonal compression tests. Additionally, modeling was performed in a computer program. We get capacity diagram through load-deformation behavior, which also allowed us to calculate: ductility, seismic behavior factor, secant stiffness, energy dissipated by damping, maximum strain energy, equivalent viscous damping and types of fissures. We use seismic equipment to calculate the period of the structure and we compare this value with the value obtained in the modeling. Also, it is proposed that wall has a steel mesh coating and mortar layer like a solution of toxic combustion of expanded polystyrene. Subsequently, a comparative economic analysis was carried out between the construction of a wall built with our new system and other wall built with the conventional system. Finally, we proposed an architectural design, and some solutions for sanitary installations of a double deck house.
