［摘要］新型钢-混凝土双面组合作用连续梁通过在中支座处负弯矩区钢梁下翼缘重新组合一块混凝土板形成整体截面，可有效增强钢梁下翼缘的稳定性，提高截面刚度和极限承载力。从该双面组合梁的应用现状、力学特性、界面滑移和裂缝控制4个方面进行了文献综述，对国内外已开展的相关研究和应用工作进行了分析。综述表明，现有的相关研究和应用工作大多集中在桥梁工程中，而在民用建筑工程领域的研究和应用较少。国内外对该双面组合梁的基本原理和受力性能的研究缺乏系统性，研究成果尚需试验验证；  我国对该双面组合梁的研究应用工作尚处于起步阶段，需加快理论计算研究，以满足设计需求。

Abstract:The new type of steel-concrete double-sided composite continuous beam is formed by reassembling a concrete slab at the lower flange of the steel beam in the negative moment area at the middle support to form a whole section, which can effectively enhance the stability of the lower flange of the steel beam and improve the section stiffness and ultimate bearing capacity. A literature review was carried out from the four aspects of the application status, mechanical properties, interface slip and crack control of this double-sided composite beam, and the relevant research and application work that has been carried out at home and abroad was analyzed. The reviews show that most of the existing researches and applications are focused on bridge engineering and few in civil construction engineering. The research on the basic principle and mechanical properties of the double-sided composite beam at home and abroad lacks systematicality, and the research results still need to be verified by test; the research and application work of the  double-sided composite beam in China is still at the initial stage, and it is necessary to speed up the theoretical calculation research to meet the design requirements.

Keywords:steel-concrete double-sided composite continuous beam; composite beam; composite structure; literature review; research status
