MEASURING METHOD AND APPARATUS OF BRIDGE DISPLACEMENT BY MEASURE OF STRAIN

摘要

PURPOSE: A displacement measurement method of a structure using the strain measurement and a linear variable displacement transducer using the same are provided to increase the displacement measurement reliability of structure and to measure the accurate displacement of the structure. CONSTITUTION: A strain at the plurality metering point of structure is measured at a strain gauge(S1). An influence factor of moment by the unit load about each metering point is computed(S2). The soft calculation of the strain-equivalent load about each metering point is computed and the modulus of rigidity of the strain-equivalent load is computed from matrix inverse(S3).
