| Abstract: | By introducing the strain rate effect into this paper,the dynamic analysis module ABAQUA/Explicit is used to simulate and analyze the fracture behavior of reinforced concrete beams under different monotonic loading rates.By comparing the results of the analysis under different loading rates,the performance of reinforced concrete beams is discussed.The results show that the fracture behavior of reinforced concrete beam under dynamic loading force significantly change,the bearing capacity of reinforced concrete beam increases with the increase of the loading rate,and the ultimate strength improves more obviously than the yield strength. |
