［摘要］中國國家博物館鋼桁架結(jié)構(gòu)跨度大、荷載大，使得鋼桁架與混凝土結(jié)構(gòu)連接處的反力巨大。為了使鋼和混凝土協(xié)調(diào)工作，連接部件的合理設(shè)計是一個關(guān)鍵問題。本項目中，鋼桁架與混凝土結(jié)構(gòu)主要有兩種位置關(guān)系，一種是鋼桁架與混凝土結(jié)構(gòu)側(cè)面連接；另一種是鋼桁架與混凝土結(jié)構(gòu)頂面連接。對這兩種連接方式分別進(jìn)行了方案的對比和介紹。對于側(cè)面連接區(qū)域，采用了暗桁架的連接方式，并將暗桁架桿件形式從實(shí)腹式截面調(diào)整為兩塊鋼板，在保證了有效傳力的同時，滿足了鋼筋布置的要求。同時還進(jìn)行了有限元分析，對節(jié)點(diǎn)設(shè)計方法給予了驗(yàn)證。對于頂面連接方式，采用與施工方案相結(jié)合的節(jié)點(diǎn)設(shè)計方式，通過滑動支座釋放部分水平反力。通過分析計算確立了合理的連接構(gòu)造。

Abstract:The steel truss of National Museum of China is a large-span and high-loaded structure system, which produces high reaction force on the connection between steel truss and concrete structure，thus the design of reasonable connection is a crucial issue for the coordination between steel and concrete. There are mainly two connection types between steel truss and the concrete structure in this project: the steel truss is connected on the side face of the concrete structure, and the steel truss is located on the top face of the concrete structure. These two connection types were introduced respectively. For the side connection style, hidden truss was adopted, while the steel plates were used in replace of the solid shape steel for members of the hidden truss. This method could assure the force transfer effectively and meet the requirement of the arrangement of rebar simultaneously. Meanwhile, finite element analysis was carried out to verify the connection design measurement. For the top connection style, the connection design need to combine with the construction measurement. The slipping bearing was used in the construction period to release part of the horizontal reaction force. Based on the careful analysis and calculation, the connection structure was properly established.

Keywords:National Museum of China； steel truss； connection between steel truss and concrete structure； hidden truss
