| Abstract: | Based on experiment of bonded prestressed reinforced simply supported beam, this paper discusses the concept of dynamic stiffness reinforcement, and according to the test results of reinforced beam, the inherent frequency calculation formula is deduced. The results is verified on using large-scale finite element analysis software ANSYS. it is show that the calculation formula has better practicability, it can provide certain reference for bonded prestressed reinforced design. |
