Abstract

The vibration mode of curved box-girder bridge was decomposed into 4 mode direction factors by energy ratios. 4 two-span curved box-girder bridge models were built taking span ratio as parameter. The modal characteristics and the mode direction factors were analyzed along with varying span ratio. It is advised that the stiffness increases more slowly than mass for curved box-girder bridge, the vertical bending mode must be taken account, the torsion mode factor decreases with the decreasing of span ratio, the summit of longitudinal movement direction mode factor appears on higher modal orders, and high order modals must be considered when designing.
