Paper Abstract

This paper is focus on the applications of EM sensor in stress measurement for steel cables used in bridges. The calibration of the EM sensors has been investigated. A new methodology makes this calibration process done either in the laboratory or in the field. Application of EM sensors on QianJiang No.4 Bridge to monitor the stresses of key hanger cables and post-tensioned cables is presented. Furthermore, a multi-EM sensor configuration has been developed to monitor the stress in a multi-strand-cable system.
