Dynamic Performance Assessment of a Novel Hybrid Bridge System with Spread Steel Box Girders

The dynamic performance of a new bridge system utilizing hybrid spread steel box girders, in which the steel box girders are spaced apart instead of conventional multicell box girders, was evaluated based on field tests and numerical analyses. In the live-load-testing program, the novel bridge superstructure was instrumented with a photogrammetric photoelectric transducer to measure the deflection responses of the spread steel box girders at...
