Research of longitudinal aseismatic performance for a long span railway simply-supported steel truss girder bridge on tall piers with non-linear viscous dampers is presented.

The through steel truss girder bridge can be a competitive bridge type for medium span highway bridges owing to the advantages of its low architectural height,fast construction speed and good durability.

Research on damage degree identification of steel truss bridge based on model updating;

With the speed upgrade of railway vehicle,the problem of lateral vibration amplitude exceeding limit,which is caused by inefficiency of lateral stiffness,appears in some steel truss bridges on existing railway.

The analysis of ultimate bearing capacity of big eccentric external cable concrete simple supported beam bridge;

In this paper,the optimal design model of the seismic absorption and isolation system for railway simple supported beam bridges considering the running safety of vehicles is established.

In the end the ELSDR method is introduced for the anti-sesmic displacement restrictor design of simple supported beam bridge.

Study on seismic semi-active control algorithms for simply supported beam bridge;

To enhance the aseismatic ability of simply supported beam bridge is an important content of earthquake prevention and disaster reduction.

Besides, the free frequencies for the vertically loaded simply supported beam bridges with different spans are investigated.
