摘要
近几年不断出现的复杂造型的结构体系使结构中构件与构件的连接方式日趋复杂,而节点设计是结构是否安全可靠的保障,但对于这种多样化与复杂性的节点,规范未能提出明确的计算公式。相比试验研究在具体工作中受到的多方面限制(比如资金、工期),三维实体技术、有限元分析为这类问题提供了较为简便的解决办法。以杭州奥体博览中心主体育场为背景介绍了工程中典型铸钢节点的优化设计与有限元分析。
In recent years, the emerging complex model structure system makes the connection model of members more and more complex. Joint design guarantees the structure safety and reliability security. But for such complex joints, the codes have no explicit formulae. Test and research are limited by some conditions such as cost and construction period in practice engineering. So, 3-D model and finite element analysis are effective to solve the problems. In this article, the optimization design and finite element analysis for the cast steel joints are introduced based on Hangzhou Olympic Sports Center Stadium project.
