Research On Behavior Of Concrete Member Under Torsion Based On Concrete Mechanics

With the rapid development of civil engineering, old and younger science of concrete be faced with new challenge for teaching way and means is lagging. With the development and the extensive applications of computer and network, network education, a modem long-distance education method, becomes a main way for people to obtain knowledge and learn all lifetime. Network Course is the important resource for Network Education. It is direct embodiment of the teaching contents, platform is the foundation to actualize the network teaching activities.The paper is used to apply for national perfect curriculum. The paper, which is based on concrete mechanics, systematically summarized the history of theory about torsion, and researched on performance of member under torsion.In the first part, the paper simply summarized the history of theory about torsion and putted forward the background and meaning of research.In the second part, the paper studied and generalized the mechanics model and analysis of the member under torsion. In addition, the paper did an analysis of the whole process with C language. In this analysis, the paper contrasted the calculating data and code values, and did an analysis of mechanics behavior of torsion, and did an analysis of Strength ratio of distributed steel ratio of reinforcement concrete strength. Etc. These perfectly reflected the mechanics behavior of torsion.In the third part, the paper studied and generalized the mechanics model and analysis of reinforced concrete members subjected to combined torsion, analyzed relevance of bend-torsion under stress. The paper simplified the model of bend-torsion under stress by combining with mechanical analysis. Finally, the paper obtained the relativity formulas of bend-torsion, which provided reference for uniform design formula about calculation of bend-torsion.In the forth part, the paper introduced development status the definition and the characteristics of the network course. Based on these studies, the paper put forward the syllabus of the network course, which is reference to apply for national perfect curriculum.At last, Based on mentioned above, the paper put forward some problems which needed further research.
