Study on Dynamic Characteristics of Bonded Prestressed Reinforced Simply Supported Beam

Based on experiment of bonded prestressed reinforced simply supported beam,the concept of dynamic stiffness reinforcement is discussed,and according to the test results of reinforced beam,the inherent frequency calculation formula is deduced.The results are 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.
