摘要
预制混凝土外挂墙板是一种高性能非承重外围护墙体,其与主体结构之间的连接方式是影响结构抗震性能的关键因素.外挂墙板与主体结构之间的连接方式主要分为刚性连接、柔性连接和耗能连接三类.研究者围绕上述三种连接方式,针对新型连接节点研发以及各类连接对主体结构抗震性能的影响展开了研究.结果表明,墙板与主体结构采用刚性连接方式时,二者之间会产生较大的相互作用,外挂墙板会增加结构的刚度、强度和地震响应;合理的柔性连接节点可以实现墙板与主体结构间的相对独立变形,从而减小墙板对主体结构影响;柔性连接方式对于节点的构造方式、施工质量和精度要求较高;耗能连接可以利用墙板和主体结构间相对变形耗散地震能量,有效控制主体结构和墙板自身的损伤.对上述研究进行了回顾和综述,并对可进一步开展的研究进行了展望.
Abstract
Precast concrete cladding panel serves as a high performance non-structural envelope element.The connection system between the cladding panels and the main structure is a critical factor affecting the seismic performance of the structure.The connection methods between the cladding panels and the main structure can be classified into three categories:rigid connection,flexible connection,and energy-dissipative connection.Researchers have developed some new connections and studied their effects on the seismic performance of the main structure.The results demonstrated that when rigid connections were used between the panels and the main structure,significant interaction occurred,resulting in increased structural stiffness,strength,and seismic response.Proper flexible connections could facilitate relative independent deformation between the panels and the main structure,thereby reducing the impact of the panels on the main structure.Flexible connections were highly dependent on the construction manner,as well as the quality and precision of the construction.Energy-dissipative connections could utilize the relative deformation between the panels and the main structure to dissipate seismic energy,thereby proficiently controlling the damage to both the main structure and the panels.The paper provided a review and summary of the aforementioned research and offered prospects for further studies.
