Test and Simulation Analysis of Flexural Behavior of Damaged Reinforced Concrete Beams
In order to study the influence of the bearing capacity,the test method of the bearing capacity of the bearing beam.The nu-merical analysis method is used to simulate the static load test of the damaged beam,and the regression method is used to systematical-ly analyze the test and numerical analysis results,showing the influence law of the longitudinal reinforcement ratio and the strength of concrete under different damage conditions:When the reinforcement rate of longitudinal reinforcement is 1.0%,the damage degree is 60%～70% of the ultimate bearing capacity of the original beam,and the ultimate bearing capacity of the damaged beam is between 85%～90% of the original beam;If the damage degree is 70%～90% of the ultimate bearing capacity of the beam,the ultimate bear-ing capacity of the damaged beam is 80%～85% of the original beam.The ultimate bearing capacity of the damaged beam increases with the increase of longitudinal reinforcement ratio and concrete strength,and the increase range is 35%～53% and 10%～21% re-spectively.
