Description In this work, an experimental study of low cycling fatigue in reinforced concrete elements with dominant flexural behavior is developed. The reinforced concrete elements are subjected to cycles of displacement until rupture. A total of two bending beams were tested. In each cycle, the degradation of the resistance and rigidity due to the effect of low cycling fatigue is evaluated. Preliminary results and observations are presented and discussed. The tests are relevant to develop an analytical model of non-linear behavior that describes the degradation of strength and rigidity of reinforced concrete structures subjected to severe earthquakes
En este trabajo se desarrolla un estudio experimental de la fatiga de bajo ciclaje en elementos de concreto armado con comportamiento dominante a flexión. Los elementos de concreto armado son sometidos a ciclos de desplazamientos hasta la rotura. Un total de dos vigas a flexión se sometieron a ensayos. En cada ciclo se evalúa la degradación de la resistencia y rigidez por efecto de la fatiga de bajo ciclaje. Los resultados preliminares y las observaciones son presentados y discutidos. Los ensayos son relevantes para desarrollar un modelo analítico de comportamiento no-lineal que describa la degradación de resistencia y rigidez de estructuras de concreto armado sometidas a sismos severos
