摘要
钢-混组合结构桥梁作为能实现可持续桥梁工程的结构形式之一,有良好的综合技术经济效益和社会效益,日益受桥梁工程界欢迎。钢-混组合结构能充分发挥混凝土和钢材各自的材料性能优势,以其整体受力的合理性、经济性、便于施工等突出优点,已广泛应用于结构工程许多领域。为促进桥梁建设向装配化、绿色化及智能化的转型升级,在中小跨度桥梁中推广使用钢-混组合结构面临机遇与挑战。从两大类方向对2020年度文章进行搜集、分类、回顾、综述,包括各式常用剪力件研究以及组合梁研究。剪力连接件研究内容涵盖栓钉连接件、PBL连接件、螺栓连接件、连接件的基本力学性能,以及连接件的耐久与退化性能;组合梁研究进展包括理论模型、组合效应与空间行为、组合梁负弯矩区性能、组合梁动力特性、组合梁劣化性能与检测加固、组合梁施工方法等方面的研究。
Steel-concrete composite bridges,one of the sustainable structural forms,have excellent composite technical,economic and social results,and are increasingly popular in the bridge engineering.The steel-concrete composite structure can give full play to the material advantages of concrete and steel,and has been widely used in many fields of structural engineering,because of the reasonable load transfer,the economic efficiency,and the ease of construction.In order to accelerate bridge construction to assemblage,greening and intellectualization,promoting the use of steel-concrete composite structures in small and medium-span bridges faces opportunities and challenges.Two major categories,including research on commonly used shear connectors and steel-concrete composite girders in 2020,are collected,categorized and reviewed.Research on shear connectors covers the basic mechanical properties of stud connectors,PBL connectors,bolt connectors,and improved connectors,as well as the durability and degradation properties of connectors.Research on composite beams includes theoretical models,combined effects and spatial behavior,performance in the negative moment zone,dynamic characteristics of composite beams,deterioration performance,detection and reinforcement,construction methods.
