| Abstract: | The energy losing of the unbonded prestressed cable in the pipeline of frame beams is studied in this paper.The unbonded prestressed concrete frame is double-span,single-story,when it is in the elastic displacement,the energy losing formula is put forward to in this paper.Furthermore,the damped coefficient,the vibration frequency and the diameter of the prestressed cable are the influencing factors to the energy losing. |
