| The Curtain Wall (roof) industry starts in 1978 in China. After twenty years rapid development, especially in 90s, China has become the first-range producer and costumer at the beginning of 21 century. Nowdays, thousands of Curtain Wall enterprizes of different scales rival, howeven, traditionally they have a very low work effeciency. Under such a circumstanle, the structure caculation softwares for Curtain Wall spring out.The strucuture calculation software, which is used in Curtain Wall design does the safty and strength caculation for all kinds of elements in the projects. The system is a human-computer one, which is based on the theory mechanics, material mechanics and structure mechanics etc, which by using computer and information techonology helps to do structure calculation and element safty and strength caculation and find the most suitably materials. The system provides the data such as stress and displament in all kinds of load cases, and it helps the costumers to find the most suitable materials. It helps to make the project safe and economic. Calculating, analysing and judging by human-computer interactive function the enterprises can do the project more safely and economically.The design considers the latest devolopment and research results of the structure calculating software for Curtain Wall, relates to the charecteristics of our own enterprise, and puts forward the Muti Span Beam model, whose application in the projects is the exclusively leading techonology of out enterpise. In the paper the design function and realization of structure calculating system for Curtain Wall are introduced.The structure calculating system for Curtain Wall provides 6 kinds of Curtain Wall of Aluminium Plate, Stones, Glass and other materials, and the calculation for the mullion, plate and linking element in Curtain Wall.The paper tries use the way of OOP and is guided by the software engineering thinking. The profound design analysis and realization of the software are presented. |
