摘要
装配式剪力墙结构拼装时存在大量的水平接缝和竖向接缝,由于剪力墙的刚度较大,接缝连接处易存在刚度不足引起的损伤集聚问题,成为影响结构整体性和抗震性能的决定性因素。总结了国内外正在发展的预制装配式剪力墙结构水平和竖向接缝的连接形式,并对各类连接形式的构造特点、抗震性能、应用优势和技术瓶颈进行了系统阐述和分析,在此基础上探讨了装配式剪力墙结构接缝连接技术的发展方向。结果表明:目前湿式连接技术已较为成熟且被广泛应用,但仍存在现场湿作业量大、质量不易检测和控制等问题;干式连接技术工业化程度高,但对施工精度的要求也高,可能产生的螺栓松动、锈蚀以及磨损问题限制了其工程应用;将消能减震技术融入竖向接缝连接,利用超高性能混凝土实现水平接缝连接,并结合可恢复功能防震技术,是未来装配式剪力墙结构高质量发展的新增长点。
There are many horizontal and vertical joints when assembling prefabricated shear wall structures.In view of the large stiffness of the shear wall,the connection at joints is prone to be damage accumulation caused by insufficient stiffness,which has become a decisive factor affecting the integrity and seismic performance of the structure.The connection forms of horizontal and vertical joints of prefabricated shear wall structures under development in China and other countries were summarized,and the structural characteristics,seismic performance,application advantages and technical bottlenecks of various connection forms were systematically expounded and analyzed.On this basis,the development direction of connection technology of prefabricated shear wall structures was discussed.The results show that at present,the wet connection technology has been relatively mature and widely used,but there are still some problems such as large amount of wet operation on site and difficulties in detecting and controlling the quality.The dry connection technology has a high degree of industrialization,but it also has high requirements for construction accuracy.Moreover,the possible bolt loosening,rust,and wear issues limit its engineering application.Integrating energy dissipation technology into vertical joints connections,utilizing ultra-high performance concrete to achieve horizontal joint connections,and combining with recoverable function seismic protection technology,is a new growth point for the hig-quality development of prefabricated shear wall structures in the future.
