Evaluación del riesgo estructural en edificaciones ante movimientos en masa detonados por lluvias: Caso de estudio Urbanización Cerro Mirador, Loja

Abstract

Abstract: This study evaluates the structural risk to buildings in the Cerro Mirador Urbanization, Loja, from mass movements triggered by intense rains. The most vulnerable areas are identified through soil studies, analysis of annual rainfall, and evaluation of natural drainage. Furthermore, a visual and photographic inspection of 45 buildings is carried out, identifying damage such as cracks, subsidence, and wall collapse using evaluation forms based on the Cooper AH methodology. Additionally, the direction of mass movement is determined with the aid of specially designed crack gauges. The data collected in the field allows for the determination of the degree of impact, ranging from V=0 (no damage) to V=7 (total damage), and the risks to residents and neighboring buildings if the buildings are severely affected. Finally, a zoning map is included to delimit the area of ​​influence and establish the level of hazard. In the present study, this level is classified as 4, corresponding to a significant hazard, which implies the need for specialized assessments to guarantee adequate safety conditions.
