| dc.description.abstract | En este proyecto de investigación, se estimaron las deformaciones en el acero de refuerzo longitudinal y transversal de una viga de hormigón armado de 2f½”. Además, se midieron los desplazamientos en el centro del vano junto con las cargas, lo que generó la fisuración de la viga de dimensiones 180 mm × 240 mm × 3100 mm. Los desplazamientos se realizaron utilizando un transductor de desplazamiento variable lineal y se utilizaron galgas extensométricas para medir las deformaciones. Finalmente, las mediciones de la carga aplicada se obtuvieron con una celda de carga Pinzuar/Modelo 100/20T. Las propiedades físico-mecánicas del hormigón utilizado se determinaron mediante ensayos de resistencia a la compresión a los 28 días y el módulo de elasticidad. Para ello, se utilizó un marco portante para soportar la viga en tres puntos para la aplicación de la carga. Los datos se recopilaron directamente en el equipo Quantum/X2 y se analizaron con la ayuda del software Catman/AP. Las deformaciones máximas encontradas en el ensayo de flexión a tres Los puntos de la viga de hormigón armado no superaron los 8483 µm/mm, presentando una falla en el centro de la viga debido a la fluencia del acero tensado para una carga máxima de 3115 kg. Finalmente, el comportamiento físico de la viga de hormigón armado al aplicar una carga permite evaluar y optimizar este tipo de sistemas. | en_US |

| dc.description.abstractenglish | In this research project, the deformations in the longitudinal and transverse reinforcing
steel of a reinforced concrete beam with 2f½” were estimated. Additionally, the displacements
in the center of the span were measured together with the loads, which generated the cracking of
the beam of dimensions 180 mm×240 mm×3100 mm. Displacement were performed using a
linear variable displacement transducer, and strain gauges were used to measure
deformations. Finally, the applied load's measurements were obtained with a load cell
Pinzuar/Model-100/20T equipment. The physical-mechanical properties of the concrete used
were determined through compressive strength tests at 28 days and modulus of elasticity. For
this purpose, a load-bearing frame was used to support the beam at three points for load
application. The data was collected directly on the Quantum/X2 equipment and analyzed with
the help of the Catman/AP software. The maximum deformations found in the bending test at
three points in the reinforced concrete beam were not greater than 8483 µm/mm, presenting a
failure in the center of the beam due to the creep of the tensile steel for a maximum load of
3115 Kg. Finally, the physical behavior of the reinforced concrete beam with applying a load
allows evaluating and optimizing this kind of systems. | en_US |
