1前言随着全球化、知识化和信息化时代的来临,信息日益成为主导全球经济的基础。在现代信息技术的影响下,建设项目的信息化已经成为一个炙手可热的话题。建筑工程项目涉及专业众多,生命周期长而建设周期短,其中结构设计是抗震、安全等因素的重要保证。传统的基于平面CAD设计技术只涉及建筑全生命周期某个阶段的、某个专业的领域应用,信息共享与交换以人为主,并需借助多方软件的辅助协同,无法满足目前建筑业向低能耗、低污染、可持续发展方向的发展趋势[1]。建筑信息模型
1 Introduction With the advent of the era of globalization, knowledge and information, information has increasingly become the basis of the dominant global economy. Under the influence of modern information technology, the informatization of construction projects has become a hot topic. Construction projects involving many professionals, long life cycle and short construction period, of which structural design is an important guarantee for seismic, safety and other factors. Traditional CAD-based design technology only involves a certain stage of the whole life cycle of a building, and a professional field of application, information sharing and exchange are people-oriented. With the help of multi-party software, it can not meet the current low energy consumption , Low pollution, the trend of sustainable development [1]. Building Information Modeling
