Virtual Laminated Three-dimensional Degradation Unit Bridge Structural Analysis And Programming

The text include two aspects, one is the universal finite element method (FEM), the other is bridge special FEM. And two viewpoints are used in it, one is the theory of FEM, the other is the practical programmakingThe virtual laminated 3 dimensional degenerated element with vivid character is introduced in this papers and a large-scale computer program of FEM-Bsap is manufactured0The aim of this papers is to expound all kinds main question from theory to practice and put up the back-ground and structure of a large-scale computer program of FEMO These will be very favorable to teaching ofFEMOIn the same time, the family of the virtual laminated 3 dimensional degenerated element which is used in the program and explained in detail in this papers isn抰 empoldered long before and has far-ranging to these types of element for continuing to spread, apply, research and consummate0In addition, some current advantaged computer technology is used to make simple pre- and post - processing program in order to exemplif~r and calculate easily in the process of teaching and researching0Professor Xin Xu in Zhejiang university point out that a man who want to acquire the experience and technology of manufacture FEM program must have contact with some large-scale and highly quality FEMsoftware0The text also hope of helping those people who are dedicating to and will dedicate to the FEM program manufacture0At last, some field that can continue to develop in the Bsap are researched and some advice are i0...
