Computer-aided Design System For Steel Plate Concrete Chimney

The developing course on assistant designing system by computer is analyzed in the text, andit is especially analyzed that the deveoping status in engineering group now. By investigatingassistant designing software on chimney inside it is found that only set designing software ofreinforced concrete chimney was opened out in DOS on fortran in the northwest electric powerinstitute in l980s. Due to the localization of computer technology, the software is not fit to thedevelopment of computer obviously. According to some stipulate of chimney standard, it isconfirmed that the calculate step of chimney, on the base of confirmation, the tradition method ofcalculation is improved and the matrix-stiffness-displacement method is instead of the Stodala-iterative method, which can avoid errors on the event of high shake-form. DELPHI 5, which is anew tool with OOP, is used to workout the segment of chimney's frame calculation which isencapsulation to standard genus for the sake of use later These largely increase the efficiency ofcodes repeated uses.Because of adopting the new tool, the interface looks more amicable, greatlysimplifying systemic step and increasing systemic easy. In the way of graphical interfaces,AutoCAD2000 is adopted as platform, using VC++ 6.0 to workout ObjectARX for the interfaceeach other, and carrying out automatic creation of shop drawing bringing out the learning courseof extension of intelligent function on checking number. A few attempts are done. Validating byexample, the system has much virtue such as the neighbor interface, agility, nice calculation,reliability, fast and precise plot and hold out continual exploiting work later.
