It mainly make some comments about the present research situation of the stiffening plate of the simple narrative,and also describes the types of the stiffening plate. There are two,one is the kind of a thick wall,the other is a thin wall plate,and their the theory of the stiffening plate was used to real engineering application,finally it describes the performance of the stiffening plate,including mechanical properties and operational performance,to provide reference for further research on structure.
