Evaluación de la temperatura superficial en losas de concreto de edificaciones en la ciudad de Bogotá y el Municipio de Simijaca

Abstract

In civil engineering, concrete slabs are used to provide flat surfaces; however, the appearance of cracks, fissures and deformations in them, lead to a study to find out their possible causes and thus offer structures with optical parameters for their use. In Colombia, these designs are based on the NSR 10 Standard, which includes the most efficient techniques and designs. However, it is currently a problem that is being observed in construction designs. In this research project an analysis of the thermal gradient in two types of concrete slabs is carried out, the first one located in the municipality of Simijaca, Cundinamarca and the second one in the city of Bogotá, corresponding to a solid slab and a lightened slab respectively. For this purpose, photographs were taken with the Flir thermographic camera to obtain temperatures in the field. These data were taken during 27 days in the municipality of Simijaca and 20 days in the city of Bogota. In this way, the data was analyzed by numerical modeling and supported by meteorological stations such as IDEAM, CAR and NASA. Consequently, it ends with the comparison of results that allow us to demonstrate the effects generated by the thermal gradient in the plates and its implication in the processes of expansion and contraction of these
