A vast amount of information data must be inputted before finite element calculation of steel buildings, such as node information, element information and load information. So it is necessary to develop a computer aided design system with 3D interactive function. A CAD system for steel buildings based on objectarx was developed with AutoCAD API and the Object-oriented technique. In this paper, some key programming technologies were studied, including design of classes of structure, identification of floor system and implementation of reactors.

A finite element study of the wall pressure by the stored solid in the ground-supported silo is presented in this paper. Firstly, the static wall pressure is investigated and the Janssen Formulation is suggested to be modified according to the finite element analysis. Secondly, the dynamic wall pressure is investigated and the coefficient of dynamic wall pressure for wheat is put forward.
