| Abstract: | The paper has supposed the movable girder frame of water press to be a cross bar system and made an elasto plastic analysis of that part using finite element method.This paper has also derived the unit stiffness matrix of bar element on which the moment of some nodes is over the elastic ultimate moment and discussed the convergent properties of computing method. |
