为了有效降低传统结构工程的耗材量,提高工程经济效益,钢管混凝土结构应运而生。本文讲述了钢管混凝土的发展历史以及在近年来的发展趋势,分析了钢管混凝土结构的受力机理、强度、刚度、延性等相关性质。最后总结了钢管混凝土设计时的关键点,并介绍了几种具有发展潜力的新型钢管混凝土结构。
In order to effectively reduce the amount of supplies of traditional structural engineering and improve the economic benefits of the project, the concrete-filled steel tube structure emerges at the historic moment. This paper describes the development history of steel tube concrete and its development trend in recent years, and analyzes the mechanical properties, strength, stiffness, ductility and other related properties of concrete filled steel tube. Finally, the key points of CFST design are summarized, and several new CFST structures with development potential are introduced.
