Eccentric Load Coefficient of Live Load Normal Stress of Continuous Composite Box-girder Bridge with Corrugated Steel Webs

A study of the eccentric load coefficient of continuous composite box-girder bridge with corrugated steel webs due to eccentric loading at the transverse position on the top flange were presented. The distribution laws of the eccentric load coefficient along the spans were developed by the finite element analysis comparing with several simplified methods commonly used in engineering. The results show that, for the continuous composite box-girder bridge with corrugated steel webs, it is not advisable to use a uniform eccentric load coefficient of each section along the bridge. A selection of practical analysis methods for the eccentric load coefficient is proposed for the engineering design.
