Analysis on deflection control in cantilever construction of large-span pre-stressed continuous rigid frame bridge;

The bending response of bridge structural members strengthened with high-performance ferrocement considering fatigue load were experimentally investigated.

Preliminary research on the cause of the cracks in thin-walled flexible piers of continuous rigid frame bridges;

With continuous rigid frame bridge span increasing,cantilever construction of large tonnage anchor are also becoming more common,but local stress distribution is complicated on prestressed anchorage zone of thin concrete box girder webs by the large tonnage,which reveals its distribution of post-tensioned concrete bridge structure to be solved in the future.

The semi-active control effect calculation and analysis are performed on a four span continuous rigid-framed bridge under seismic travelling waves with different apparent surface velocities,and comparison is made between the calculating results in this case and those under uniform ground motion input.

The seismic response calculation for a four span continuous rigid-framed bridge under seismic traveling-wave inputs is performed.
