Abstract

During the cantilever construction stage, bridge galloping stability problem caused by wind load cannot be ignored because the structure stiffness is small. Thus, it is necessary to study galloping reliability assessment of long-span continuous rigid-frame bridge. Taking Beishan bridge as an example in the paper, the occurrence of galloping is firstly analyzed qualitatively by wind tunnel test. Then, with the galloping critical wind velocity determined by wind tunnel test as structure resistance and stochastic wind speed at the site of the bridge as load effect, an probability evaluation model for galloping reliability assessment of long-span continuous rigid-frame bridge is established based on the existing structure reliability theory. In the end, the galloping reliability assessment and parametric sensitivity for Beishan bridge are given.
