一般来讲，在斜拉桥诸多构件当中，由斜拉索风荷载引起的桥梁特殊位置弯矩响应占着不小的比重。
In general, to the components in the cable-stayed bridge, the load moment of key position caused by the wind load on the cable take a large proportion of total.
在风荷载或地震荷载等水平荷载及竖向荷载共同作用下，板柱节点除了要传递垂直剪力外，还必须传递较大的不平衡弯矩。
In addition to vertical shear force, slab-column connections also have to transfer unbalanced moment due to combined vertical and lateral forces as a result of wind effect or earthquake excitations.
结构最优立面形式应按风荷载的弯矩反算得到。设计中宜用刚性腹杆体系而非柔性腹杆体系；
The rigid web member system had better be used rather than flexible web member one to raise the structural stiffness.
