［摘要］结合某实际工程介绍了大跨度PRC框架结构顶层边节点在恒载作用下铰接(柱顶铰接)、在活载(包括地震作用和风荷载)作用下刚接的结构设计方法，以及“先铰接后刚接”的节点构造。采用这种设计方法，可使大跨框架结构设计更为经济合理，施工也较为方便。

Abstract:With the practice of some actual projects in Chongqing, the design and application of first-pin-then-rigid joints for side column on top floor of long-span PRC frame structure are introduced. The side column joints first act as pinjoint when dead load is exerted, then act as rigid-joint when other live loads present, so as to minimize the total design bending moment at the side-top joint. Adopting this design philosophy, reasonable economy and construction convenience can be achieved.
Keywords:long-span; frame structure; pin-joint; rigid-joint; steel tube concrete short column
