ANALYSIS AND ASSESSMENT ON DEAD LOAD AND DYNAMICAL LOAD TEST OF BINWANG BRIDGE
After working for a long time, some elements such as operating bridges have some changes, in material and geometric form of structure. Binwang Bridge is a through tied arch bridge with concrete-filled steel tubes. The distance between the bearing is 55.25m+ 80m+52.25m. The bridge was open to traffic in 1998. The static loading and active loading tests are carried out for its current situation. The static and dynamic test of this beam is for verifying the dependability of the theory analysis and design method, examining construction quality, and judging supporting capacity. The selection of static loading efficiency η is taken into account, and the control of loading, deformation and the set of reasonable loading-time are paied more attention to. The assessment analysis based on the tests data and theoretical calculations showed that the strength and rigidity of each control section of the bridge satisfies the design requirements. And the lateral stiffness is large enough and there is considerable capacity of resisting overload and eccentric loading.
