Taizhou Yangtze River Highway Bridge is proposed to adopt three pylon suspension bridge designs. To figure out slip behavior of main cable against saddle for middle pylon under given circumstance, Jiangsu Provincial Yangtze River Highway Bridge Construction Commanding Department(J.P.C.D.) takes initiative to carry out study on slip resistance of main cable against saddle. This test simulate true contact between strands, wires as well as strand and saddle groove. Moreover, this test uses contact compression stress identical to the actual bridge to truly reflect slip behavior of main cable against saddle for middle pylon in three pylon suspension bridges.
