Evaluación sísmica de vivienda económica con muros de botellas PET rellenas de agregado fino en zonas rurales del Perú

The main purpose of this study was to evaluate the seismic behavior of a house whose walls are made of PET bottles filled with fine aggregates. An experimental research design was implemented, specifically adopting a quasi-experimental approach. For data collection, technical tests and detailed observation were used as instrumentation methods. The study population and sample included a house categorized as economic and located in a rural area of Peru. In the simulation, a gravelly clayey sand soil type was considered, and the masonry units exhibited an average weight of 1.1844 kg, with a specific gravity of 1.69 g/cm3. The maximum compressive strength of the mortar (f'c) reached 203.04 kg/cm2, while the average load-bearing strength of the masonry prisms (f'm) was 65.798 kg/cm2. Numerical aspects such as maximum interstory distortion were evaluated, registering 0.000009 m in the X-axis and 0.0000004 m in the Y-axis. The forces subjected to evaluation in Dynamic Shear were 17.362 tons in X and 16.964 tons in Y. It is crucial to highlight that the house fully complied with the regulatory requirements of the E-030 and E-070 standards, reaffirming its safety in the context of single-family buildings.
