This paper presents the force transfer mechanism and the fatigue performance of a pin-connection anchor of hanger for a box-type suspension bridge. Static loading tests were conducted using a full scale specimen, and contact pressure distribution and pin bending stress were measured under the design ordinary and wind loading conditions. In the subsequent cyclic loading tests, it was found that fatigue cracks occurred from seal weld at pinhole. Finite element analysis showed contact pressure distribution and the stress at welds of anchor plate and doubling plates.
