Research on CAD-based model system for steel Headframe foundation

The design of Headframes´ foundation is always a cumbersome and difficult process. Currently it need design in 3D environment and often need finite element analysis according to its importance while traditional design is focused on 2D construction drawings. This paper presents a rapidly 3D modeling method of headframes´ foundation based on the analysis of its design process and points out that the core work of 3D modeling is vertices calculation. 3D coordinates calculation method of vertices is proposed, and finally a system implementation is given. The results show that a complex modeling task of headframes´ foundation can be quickly implemented with our system. The system has been successfully applied in some project of Pingmei Group.
