摘要
本文以广深高速公路东莞段的一个钢管系杆拱桥的结构设计方案(即跨度130米,桥宽25米的钢管系杆拱桥,见图1)为对象,就该桥的整体稳定屈曲特性和自振特性进行了分析。提出了提高这种桥型面外整体稳定安全系数的几种构造措施。供工程设计人员参考。
In this paper,analysis of the structure stability and dynamic behavior of a highway steel─pipe arch─bridge with vertical hangers is presented.The characteristics of the dynamic behaviorand the stability safty and buckling model of such structure are discussed.Some considerationsfor designing such structures with better stability capacity are put forward to engineering design-ers for reference.
