摘要
预制构件连接的设计是装配整体式混凝土结构设计中最重要的环节之一,在采用灌浆套筒连接钢筋形式的装配式结构中,强连接节点和延性连接节点可以保证结构大震下的抗震屈服机制。节点强连接可通过将塑性发展区段沿构件向后推移的方法实现;节点延性连接可通过连接接头为塑性发展区段让位的方法实现。2种方法的目的相同,都是为了给构件形成塑性铰提供足够变形长度的必要条件。
The design of prefabricated member connection is one of the most important links in the design of assembled monolithic concrete structure.In the assembled structure with grouting sleeve connection steel bar,the strong connection joint and ductile connection joint can ensure the seismic yield mechanism of the structure under large earthquakes.Strong connection of joints can be achieved by pushing back the plastic development zone along the members,and ductile connection of joints can be achieved by giving way to the plastic development zone by connecting joints.The purpose of the two methods is the same,which is to provide sufficient deformation length for forming plastic hinge.
