Condition Assessment of Simply Supported Plate Bridge Based on Static Load Test

One simply supported plate bridge has turned up many diseases for its long time service.In order to keep the operational security of bridge and to provide the basis for the post-operation or transformation,its static load test is done to determine the static properties of the bridge to assess its current carrying capacity and the state.The results show that the bridge in the normal use of its carrying capacity meets regulatory requirements,and the well stiffness of the plate also meets the normal requirements.But its lateral stiffness is weak and shows a distinct phenomenon of single-beam force,leading to the actual deflection obvious asymmetry in loading symmetrical load.
