摘　　要：已有再生混凝土结构研究,一是低、中强再生混凝土为主,二是缩尺模型试验为主,三是复杂受力研究很少,基于此提出的设计理论和方法亟待完善与发展。本文分析了国内外有关再生混凝土结构研究的文献,包括再生混凝土结构受力性能基础研究,再生混凝土梁、柱、节点、剪力墙构件抗震性能研究,再生混凝土框架、框架-剪力墙结构抗震性能研究,对研究现状进行了简要评述,介绍了工程实例,指出了需深化研究的若干关键技术问题,提出了研究建议。研究表明,再生混凝土结构发展,是建筑材料循环利用和建筑垃圾资源化的重大需求,再生混凝土结构可用于建筑结构抗震设计。Current research on recycled concrete structures mainly focuses on recycled concrete in lower strength, re- duced scale, and relatively simple loading conditions. The design theory methods based on these studies have many limitations need to be improved significantly. This paper summarizes the studies on recycled concrete structures at home and abroad, including mechanical properties of recycled concrete structures, seismic performance of recycled concrete beams, columns, joints, shear walls, frame structures, and frame-shear wall structures. Previous studies are briefly reviewed, and some notable projects are presented. Based on the state-of-the-art review, this paper pro- poses some critical technical issues for future research and offers some suggestions. Previous studies indicated that the development of recycled concrete structures is a main demand for building materials recycling and building waste recycling. Also, recycled concrete structures can be used for seismic design of building structures.
