| 8. | Abstract : with the increasing of suspension bridge ? s span , the gravity stiffness of suspension cable itself is more important than vertical deflection resistance stiffness of stiffening girder which is serviced for the whole structure . in order to provide more knowledge of gravity stiffness of suspension cable , in this paper , gravity stiffness of suspension cable is formulated briefly and theoretically in case of ignoring the existing of the stiffening girder . the deformation and internal force of suspension cable can be calculated approximately in this way
文摘:随着悬索桥跨度的增大，加劲梁的竖向抗弯刚度提供给整个桥跨结构的刚度仅占次要地位，而悬索自身的重力刚度却占有重要的作用.为加深对重力刚度的进一步认识，笔者对特大跨度的悬索桥的重力刚度进行简要的理论推导，在忽略加劲梁存在的情况下，可近似地计算悬索桥的变形和内力 |
