［摘要］結(jié)合某實(shí)際工程介紹了大跨度PRC框架結(jié)構(gòu)頂層邊節(jié)點(diǎn)在恒載作用下鉸接(柱頂鉸接)、在活載(包括地震作用和風(fēng)荷載)作用下剛接的結(jié)構(gòu)設(shè)計(jì)方法，以及“先鉸接后剛接”的節(jié)點(diǎn)構(gòu)造。采用這種設(shè)計(jì)方法，可使大跨框架結(jié)構(gòu)設(shè)計(jì)更為經(jīng)濟(jì)合理，施工也較為方便。

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 pinjoint 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
