Pre-stressed concrete girder with corrugated steel web is one of the promising steel and concrete hybrid structures which are widely applied to highway bridges.In order to investigate the structural behaviour of multi-cell box girder with corrugated steel webs under eccentric loading,parametric analyses of eccentric loading effect were carried out using refined finite element analysis model.It can be found that the main parameters influencing the eccentric load factor are the arrangement of diaphragms,wide-span ratio and span-depth ratio.In addition to the end cross-beam,an internal diaphragm should be arranged in mid-span to reduce eccentric loading effect.All the findings may provide a reference for the design of multi-cell box girder with corrugated steel webs under eccentric loading.
