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.
计算发现，压杆模型或软化桁架模型所分配到的外荷载并不平衡。
The calculation results revealed that the loads carried by the compression strut or the softened truss model were not in equilibrium.
它指出，对给定外荷载下的结构，结构出现不平衡力的区域即为首先破坏的区域。
It points out that under the given external loads, the area which comes to unbalanced forces is the first place to be destroyed in the structure.
