Seismic assessment of affordable housing with walls made of PET bottles filled with fine aggregate in rural areas of Peru

Resumen

The aim of this study was to examine the seismic response of a house with walls composed of PET bottles filled with fine aggregates. An experimental research design, specifically of a quasi-experimental type, was employed. The instrumentation used for data collection included technical tests and observation. The population and sample element of the study consisted of an economically considered house located in a rural area of Peru. The simulated soil type was clayey sand with gravel; the masonry units had an average weight of 1.1844 kg and a specific weight of 1.69 g/cm3. The maximum compressive strength of the mortar (f'c) reached 203.04 kg/cm2, while the average load resistance of the masonry prisms (f'm) reached 65,798 kg/cm2. Numerical considerations, such as the maximum floor distortion, were 0.000009 m in the X-axis and 0.0000004 m in the Y-axis. The forces to be evaluated in the Dynamic Shear were 17,362 tons in the X-axis and 16,964 tons in the Y-axis. Finally, it is important to highlight that the house complied with the regulatory guidelines of norms E-030 and E-070, confirming its safety for single-family buildings.
