A stiffnessmatrix of simple rectangular plate bending element with 12 parameters expressed in explicit form is derived.
推导了以显式表示的12个自由度的简单矩形板弯曲元素刚度矩阵。
2
The geometric stiffnessmatrix is composed by the effect of axial force, bending moment and bimoment.
其中几何刚度矩阵由轴向力、双向弯曲和截面翘曲的影响组成。
3
Stiffnessmatrix of the piles was given, including bending and shear deformation effects. The damping of the entire structure was calculated using the damping of each of the sub-structures.
