| 摘 要： | 钢拱结构在竖向荷载作用下拱脚产生水平推力，将外荷载产生的弯矩转化为轴向压力，具有较高的结构承载效率。作为承受压力和弯矩为主的构件，钢拱结构的稳定性能成为研究和设计中的主要问题。钢拱结构稳定问题的复杂性导致其稳定承载力设计理论的研究和应用严重滞后于工程实践。目前国内外均无较完善的设计规范或相关规程，我国正在编制的JGJ《铜拱结构技术规程》将在大量研究成果基础上补充这方面的内容。

| Abstract: | A steel arch subjected mainly to pure compression or both compression and bending moment is controlled by its stability behavior in the design. The main characteristics are pointed out in this paper when it loses stability in its in-plane and out-of-plane of steel arch. It is the complexity of stability of steel arches that makes the study and application to them not satisfy the requirements of practical engineering,and so far there are few codes related to the stability design of arches worldwide. Recently... |
