Study on the Dynamic Response of Prestressed Concrete Beam under Explosive Load

Abstract:

The dynamic performance of the 12m span prestressed concrete beam is analyzed by finite element method. Based on the finite element analysis, with the change of the peak dynamic load, the risetime of dynamic load and the reinforcement ratio of prestressed reinforcement, the change laws of mid-span maximum deflection and the maximum stress of prestressed reinforcement in prestressed concrete beam are studied. At the same time, have further understanding to the stress and deformation of the prestressed concrete beam under explosive load. It can provide references for study on dynamic performance of the prestressed concrete beam under explosive load.
