1·Finally, several design points were emphasized such as transverse anti-overturning stability calculation, vertical stiffener layout, beam calculation, manhole and steel structure coating, etc.

最后着重介绍的设计要点有：横向抗倾覆稳定计算、纵向加劲肋设置、横梁计算、人孔设置、钢结构涂装等。

2·The main advantages are the transverse shear deformation and rotary inertia are considered naturally, and there is no restriction on the thickness of plate and height of stiffener.

主要优越性表现为：结构的旋转惯性、剪切变形等都得到了考虑，且不限制结构的板厚度和加强筋的高度。
