| Abstract: | Backgrounded with the strengthening construction of the main bridge of Burri Bridge, Khartoum State, Sudan, the vibration behavior of T-frame bridges strengthened with external prestressing is studied by means of universal finite element software ANSYS, and measures against resonance of the T-frame bridge structures are proposed. The analysis and measures in the paper are of practical values in guiding construction of bridge works. |
