摘要	Herein, the dynamic response rule of prestressed concrete beams with metal and plastic corrugated pipes with different duct grouting compactness values under moving constant concentrated loads and moving simple harmonic loads is studied. Prestressed concrete beams with metal and plastic corrugated pipes are analysed using the finite element method for the case of non-cracking. The results indicate that duct grouting compactness and forming material affect the natural vibration characteristics of prestressed concrete beams. Under identical duct grouting compactness, prestressed concrete beams with metal corrugated pipes exhibit higher frequencies compared with those with plastic corrugated pipes. The mid-span dynamic deflection of the prestressed concrete beams decreases with an increase in duct grouting compactness, which is independent of the forming material. The differences in the midspan speed and acceleration caused by the moving loads between the corrugated duct prestressed concrete beams made of metal and those made of plastic are small; this indicates that the pore-forming material has little effect on the midspan node speed and acceleration response of prestressed concrete beams.
