The whole process of forming experiment of arched groove plate is introduced in this paper, through which related parameters configuring the plate are measured and the relationship between the vane overlapping and the curvature radius is obtained.

Plastic ultimate analysis of arch folded plate structures;

This paper introduces the construction technology of large span spatial curvilinear arciform gate,and expounds the application of CAD technique in buildng three-dimensional model,then to guide the construction is an effective method to deal with complicated shapes,to reduce calculational load and to improve the construction accuracy.
