引言在古代木结构建筑在全世界得到广泛的应用,但由于当时限于人们对木结构的认知和技术水平的不足,木结构桥梁主要以原木为主,越来越不能满足比如大跨、重载的要求。随着西方工业革命的兴起近现代建筑材料主要被混凝土取代,随着国门的打开,中国也被灌入了以混凝土为主的结构体系,中国传统木结构遭受到毁灭性打击,混凝土结构在中国飞速发展,不断创造多个世界第一。但在这种高耗能材料得到广泛应用的同时,环境问题越来越令人堪忧。人们开始寻求一种能够适应现代交通要求,同 Introduction In ancient times, wood-based buildings were widely used all over the world. However, due to the limitation of people’s cognition and technical level of wood-structure at that time, the wood-based bridges were mainly dominated by logs and could not meet the requirements of large span and heavy Containing requirements. With the rise of the industrial revolution in the West, modern building materials were mainly replaced by concrete. With the opening of the country, China was also poured into a concrete-based structural system. The traditional Chinese wood structure was devastated. Concrete structures in China Rapid development, continue to create a number of the world. However, while such highly energy-consuming materials are widely used, environmental problems are becoming more and more worrisome. People began to seek a way to adapt to the demands of modern traffic
