摘　　要：在装配整体式预制混凝土结构设计中,节点设计是最重要的设计环节之一。我国装配式混凝土规范中节点的设计遵循现浇混凝土结构中节点的设计原则,即现浇等同型。在美国规范中,现浇等同型框架节点的连接方式可分为强连接和延性连接。强连接要求在设计地震作用下连接节点始终处于弹性,延性连接允许在设计地震作用下节点发生塑性变形。结合中美两国规范的要求,对梁柱连接的问题进行了探讨,并参考美国规范中强连接的设计原理,对一算例进行计算,可为类似梁柱连接设计提供参考。The design of connections is one of the most important considerations in the structural design of a monolithic precast concrete structure. In the Chinese code for precast concrete structures,the connections are designed as the cast-in-place concrete connection which is called monolithic emulation connection. In the American specification,the monolithic emulation connections in the precast concrete frame can be divided into strong connections and ductile connections. The strong connections are always in the elastic and the ductile connections can take place plastic deformation under the design seismic action. Studying on the beam-to-column connection combined with the Chinese code and American specification,take a specific example refer to the specification of strong connection calculation method in the American specification,which provides a beneficial reference for similar designs on beam-to-column connections.
