Application of Frequency Method and Jack Method in the Inspection of Steel Truss Suspension Bridge
Taking a steel truss suspensionbridge project as anexample,this paper analyzes itsdiseases indetail,compares the detectiondata of deformationof main cable,steel truss stiffeningbeamand corrosionof important components,and puts forwardsome maintenance suggestions.Through the data comparison,this paper uses the jackmethod and the frequency method tomeasure and modify the hanger rodcable force level,and obtains the cable force values of different main cable segments by means of the space node balance theory.The results showthat the spatial deformationof the main cable and hanger rodiscloselyrelatedtothe main cable and the main truss..
