Abstract Research purposes: In order to study accordion effect of the composite box girder with corrugated steel webs(CSWs), based on structure vibration theory and dynamic characteristics, the dynamic accordion effect coefficient was proposed to quantitatively analyze the accordion effect of composite box girder with CSWs. A single-box double-room test girder with CSWs was used as research object, and the numerical analysis model was established with finite element software ANSYS, to study the accordion effect and major influence factors of test girder.
Research conclusions: (1) The accordion effect of composite box girder with CSWs can be reflected effectively by the dynamic accordion effect coefficient. (2) Due to the accordion effect, the vertical and transverse bending stiffness of single-box double-room composite box girder with CSWs decreases slightly, but the torsional stiffness increases significantly. (3) The change of twist angle of CSWs has an obviously influence on vertical bending vibration accordion effect of composite box girder with CSWs. (4) The setting of diaphragm can weaken the torsional vibration accordion effect of composite box girder with CSWs obviously. (5) The setting of external prestressed tendons can influence both transverse bending vibration accordion effect and torsional vibration accordion effect of composite box girder with CSWs, but the anchor position of external prestressed tendons has little influence on all directional accordion effect. (6) The research results can provide some references for the establishment of accurate numerical analysis model of composite box girder bridge with corrugated steel webs and the accurate analysis of dynamic performance of the composite structure.
