Dynamic Characteristics of ANSYS-based Continuous Beam Bridge

Initial structural scheme of the continuous beam bridge was determined by reference to similar ones,static analysis was made on the bridge model by use of finite element analysis software ANSYS.Kinetic studies were then conducted to gain natural frequency and vibration characteristics.And finally the bridges dynamic responses under different exitations were achieved through harmonic response analysis.The results indicated that the data examined agreed with actual ones,which would surely benefit further research on other features of continuous beam bridge and structure optimization.
