预制混凝土框架结构体系研究进展

按节点核心区构造方案的不同,预制混凝土框架结构总体上可分为现浇节点核心区预制混凝土框架结构和预制节点核心区预制混凝土框架结构两类。通过对国内外相关研究成果的系统调研,总结了工程中常用预制混凝土框架结构的构件连接与节点核心区的构造特点、受力性能("等同现浇"或"非等同现浇")及设计原则。在此基础上,介绍了目前国内外有关预制混凝土框架结构体系的技术标准,并进一步展望了预制混凝土框架结构体系的研发工作。

Research Progress on Precast Concrete Frame Structures

According to the structural details of core regions, precast concrete frame structures are generally divided into two types, i.e. precast concrete frame structures with cast-in-place core regions and precast concrete frame structures with precast concrete core regions. Based on systematic investigations of relevant studies in China and abroad, the structural characteristics, mechanical behaviours and design methods of different types of precast concrete frame structures are summarized. On this basis, the domestic and foreign technical specifications of precast concrete frame structures are introduced, and the future research and development work is also prospected.
