[摘要]大連國際會議中心結(jié)構(gòu)設(shè)計中,核心筒墻體與鋼平臺桁架弦桿的連接是關(guān)鍵技術(shù)之一。實際工程中采用了墻體內(nèi)藏鋼桁架與鋼平臺桁架梁弦桿焊接后澆筑混凝土形成連接節(jié)點的方式。為驗證設(shè)計采用的墻體內(nèi)鋼桁架平面外拉結(jié)平臺桁架的錨固能力和構(gòu)造的合理性,進(jìn)行了4個桁架梁弦桿與核心筒墻體連接節(jié)點的錨固性能試驗。試驗證明墻體內(nèi)鋼桁架與鋼平臺桁架弦桿的連接性能是可靠的。

Abstract:Chord connection between the steel platform and the core tube wall is one of the key technologies in the structural design of Dalian International Conference Center. In the actual engineering, the connection is used by the way of the wall with concealed steel truss and steel truss spar platform chord welding before placing concrete. In order to verify the capacity and the structural rationality of the mentioned chord connection, four anchoring performance tests were conducted for the connection node. Experiments show that the chord connecting performance is reliable.
Keywords:core tube; steel truss platform; connection node; test
