Abstract
In this paper field tests of the Meiko-Nishi Bridge which is a 3 span continuous steel cable-stayed bridge having the center span of 405m are dealt with. A simplified cable anchorage using steel pipes to the steel box girder rather than to cross beam is adopted in this bridge.
First of all, measurements of deflections and stresses at the towers, girder and cables are discussed to check the rigidity and safety of the bridge. Then, stress distribution measurements at the cable anchorage during cantilever erection small segments and after construction are described, which were performed to capture the local stress distribution. The field test results are compared with those of the numerical calculations by the FEM and the design procedure.
