Abstract (es)
Hasta ahora, gran parte de las investigaciones llevadas a cabo para la estimación de las resistencias a compresión de los elementos de hormigón armado de nuestras estructuras, se han realizado en base a chequeos con gran número de probetas testigo, extraídas de esos elementos.
Mediante la presente investigación se estudian 185 casos reales de elementos estructurales de hormigón armado, mediante un chequeo estructural basado en la correlación de resultados entre la Velocidad de Ultrasonidos (V) y la Resistencia a Compresión (R). El estudio se desarrolla teniendo en cuenta localización de la construcción respecto a la costa marina y la edad de la propia estructura. Posteriormente se realiza un análisis estadístico con los datos obtenidos con este trabajo se ha conseguido un claro procedimiento científico de análisis de los dos métodos de ensayo y de las herramientas necesarias para realizar un completo chequeo estructural, correlación entre ellos y lo más novedoso del proceso, la confección de fórmulas matemáticas y las gráficas de correlación, que ponen de manifiesto la efectividad del procedimiento, que se propone como aportación para normativa.
Abstract (en)
So far, much of the research conducted to estimate the compressive strength of reinforced concrete elements of our structures have been made based on checkups witness many samples drawn from these elements.
By this investigation 185 real cases of reinforced concrete structural elements are studied by a structural check based on the correlation of results between the ultrasonic velocity (V) and compressive strength (R). The study was developed taking into account the location of the building relative to the shoreline and the age of the structure. Subsequently, a statistical analysis to the data obtained is performed. This work has achieved a scientific method of analysis of the two test methods and necessary for a full structural check, correlation between them and most innovative
process, making mathematical formulas and graphs mapping tools which demonstrate the effectiveness of the procedure, which is proposed as a contribution to policy.
