The Intelligent CAD System For The Design Of Reinforced Concrete Frame Structure

The structure scheme design is vitally necessary and important in the engineering structure design, but the existing CAD technology doesn't have the capability of structure design. In order to greatly reduce the civil engineering structural design cycle, reduces the design cost, improve the design quality, cause the civil engineering CAD system much more intelligent and integration. Therefore, this article studied has developed the reinforced concrete portal frame construction design intelligent CAD system. In this system the structure plan design, the load computation, the stress analysis, matches the muscle calculation, the construction drawing plan integration as a body. In the plan design, take the project example as the foundation, take the fuzzy-rough sets as the core algorithm, more systematic establishment structure intelligence plan design knowledge discovery system. In the following design, this article takes the reinforced concrete portal frame construction as the research object, and then the intelligent CAD system is established in the AutoCAD development environment.The main contents are as follows:1. Briefly introduced the fuzzy-rough sets basic definition, converted continuous attributes values to fuzzy subordinate-function values to avoid the inherent fault of directly scatter date, presented the extraction method of fuzzy-rough sets regulation in this paper.2. According to the characteristic of knowledge discovery in databases , the knowledge discovery in databases is developed as we take Microsoft Access and Visual C++ 6.0 as a tool , take the fuzzy-rough sets theory as the arithmetic foundation.3. By comparative study on several different secondary exploitation technique of AutoCAD , the most advanced technique Object ARX was selected , and also the uses of several Object ARX basic database and the steps of Object ARX application were introduced in this paper.4. In realization of Object ARX frame construction design procedure, this article introduced the definition and joins of Object ARX technology user order,...
