Article Preview

This paper presents an inclinometer-based deflection curve reproduction system which can reconstruct the deflected shapes of bridges directly. Because the conventional deflection-measuring methods are performed by collecting the deflection data at just a few discrete points along the bridges, the bridges’ deflected curves are not smooth enough. The operation of the proposed system is performed by utilizing the displacement transducer to determine the measuring intervals, using inclinometer to collect the angles of the measured points, calculating the deflection values, further applying Gradient Mean Prediction Filtering (GMPF) algorithm to filter the deflection data, and finally reproducing the deflection curves of bridges. The precision, feasibility, reliability, and effectiveness are verified by laboratory tests and field applications.
