Evaluación patológica de fisuras en sótanos, semisótanos y primer piso de la edificación de la urbanización residencial Ikona

Abstract

In the present pathological investigation, the case of study, Arcos 167 urbanization project that is being built in two stages, which are made up of two apartment towers each. Currently, the affected areas of basements, semi-basements and first floor of a tower of stage 1, are in an area very close to the foundation of the structure, which may be indicating a greater risk for the inhabitants of the urbanization given the injuries that are associated with cracks in the basement, semi-basement and first floor structures of the Ikona urbanization 167 These mechanical injuries can appear early, even from the moment of emptying and construction of the elements, when the mixtures are still in their setting process and are in plastic state or several years after being built. However, after testing hypotheses, tests and follow-up results to make a diagnosis of injuries, based on the results of the proposed tests and after reviewing existing information, it was concluded that the calculation of loads on the foundation was not underestimated and it is not a factor that could have led to the presence of damage Additionally, it is concluded that the pathology does not reveal that the structural safety to date has been compromised or has been reduced, because the causes of the symptoms are not due to low resistance of the materials, or calculation defects or problems in sizing, or lack of controls during construction or any other characteristic of the structure but to external factors. The real cause is a rebound effect of the soil, because, when excavating the adjacent tower, it could occur due to elastic deformation due to decompression of particles in the soil (expansion of the strata), and the compression loads that it assumed the compressed material generated thrust forces and in turn a "bounce" effect. Finally, the type of rehabilitation is indicated and the recommendations that the structure demands according to its current state in terms of durability as well as in relation to the bearing capacity and the recommendations for rehabilitation and quantities of work. (restoration, reinforcement, repair or other) associated with approximate costs.
