摘要
根据箱梁桥的结构特点及振动过程中的位移，由能量原理演绎出箱梁桥空间振动的阻尼矩阵，给出了阻尼矩阵的显式表达式，可供工程实际应用。
According to the structural properties and the vibration displacement of the box girder bridge, the element space damping matrix of the box girder bridge is derived on the principle of energy.The expression for this damping matrix is presented in this paper,which can be used for engineering.
