Robustness Design of Bridges Collapse Resistance

doi:10.3969/j.issn.1674-0696.2014.01.01

Abstract

Abstract: The artificial causes of bridge failures were analyzed considering designers' cognitive levels and responsibilities. Through analyzing the existing bridge accidents , a series of design suggestions were presented in tenns of structural systems and construction measures to improve the collapse-resistant capacity and the structural robustness of bridges. The proposed suggestions are practical for improving the capability to resist bridge collapse and strengthening the structural safety awareness of designer.

Key words: bridge, design, collapse, robustness

摘要： 从设计人员的认识水平和设计责任等方面分析了桥梁事故中存在的人为因素。通过吸取已有桥梁事故的经验教训，从结构方案和构造措施两方面对如何提高桥梁的抗倒塌能力、保证桥梁的整体牢固性(即鲁棒性)提出了若干设计建议。研究对提高桥梁的抗倒塌能力、帮助设计人员增强桥梁设计中的安全防范意识具有很好的实际指导价值。
