Research And Development Of Computing And Analysis System For The Building Metal Structures Curtain Walls

With the development of curtain-wall industry and people's pursuit of architectural art, curtain-wall products are widely used in China. In present design analysis process of building curtain-wall products, high individuality demand, frequent changes in the specifications, low design efficiency, high error rate, large repeated workload, great waste of raw materials, etc., are ubiquitous, for this reason, it is significant to develop the computing and analysis System for Building Metal Structure Curtain-wall Products, which suit the development of curtain-wall industry in China, can help to solve the above problems well .First, based on the analysis of similar softwares in and outside China and the study on function and building metal structure curtain-wall products, a 4-layer software architecture general scheme for the computing and analysis system for curtain-wall products, including user interface layer, functional layer, data layer and interface layer, is put forward.After that, key technologies involved in the system, such as self-organizing calculating flow, computing result list automatic generation technique, calculation of cross-section parameters and so on, are deeply researched. According to the requirement of calculating flow control of curtain-wall products structure, a self - organization theory method for calculating flow base on component is put forward, achieving the flexible and open calculating flow control and satisfying the personalized requirement of the user. While on account to the disadvantages of traditional compilation method for computing result lists, such as large workload, high error rate, complicated file output technique and so forth, a automatic generation approach of project computing result lists based on text configuration templates is presented. The profile cross section of curtain-wall product is complex, besides, combinations between profile cross section take various forms, due to it, various profile cross sections of curtain-wall product were researched and classified, the calculation method of profile cross-section parameters is constructed.Finally, based on the study on above key technologies, computing and analysis system for the building metal structures Curtain Walls was developed. The system is characterized by strongly professional, good expansibility, simple operation, etc. The system can effectively shorten the design period and improve design quality of curtain-wall products, it has been applied in several enterprises, with good application effects.
