Abstract

This paper studies the finite element (FE) modeling oriented to structural health monitoring (SHM) of long cable-stayed bridge and the optimal sensor configuration based on the structural dynamic response. Firstly , the FE model oriented SHMof Runyang Cable-Stayed Bridge (RYCB) is developed using ANSYS. Modal analysis of RYCB is carried out using the developed FE model . Taking the non-diagonal elements of the MAC matrix as target function , and increasing or decreasing the number of degree of freedom (DOF) , the optimal sensor placement of the bridge is obtained by minimizing the target function. Validation of the sensor placement is checked with the results obtained from the ambient vibration test of RYCB. It is shown that the sensor placement obtained from the measured data of RYCB is coincident with the result calculated from the FE model . The sensor placement obtained from the FE model of RYCB is valid from the experimental point of view.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
