［摘要］大連國際會議中心外圍護(hù)結(jié)構(gòu)的曲面框架通過不同節(jié)點方式與屋架、鋼平臺連接，形成復(fù)雜空間整體組合結(jié)構(gòu)。由于建筑物外形設(shè)計的多樣性，曲面框架本身的形狀、邊界條件和構(gòu)造存在相當(dāng)大的差異。研究了曲面外圍護(hù)框架中落地部分框架與鋼平臺的連接節(jié)點。這部分框架柱三向傾斜，框架柱面外的無支長度最長超過70m，最短也有60m。由于曲面外圍護(hù)框架面外剛度薄弱，需要與內(nèi)部鋼平臺、屋架拉結(jié)，形成空間結(jié)構(gòu)。這種拉結(jié)節(jié)點的構(gòu)造要求應(yīng)考慮曲面框架柱自身的承載能力、連接節(jié)點傳遞力的途徑以及相應(yīng)節(jié)點約束控制，達(dá)到整體設(shè)計要求。

Abstract:The peripheral surface frame of Dalian International Conference Center is connected with roof trusses and steel platform through different nodes, which forms a complex spatial integral combined structure. Due to the diversity of the building exterior design, the shape of curved frame, boundary conditions and the structure have great differences. The connection node between the landing part of curved outer frame and steel platform was studied. The frame column in this part is three-way inclined. The longest length without supporting the cylindrical outer frame column is more than 70m, and the shortest is 60m. Since the curved peripheral retaining frame surface stiffness is weak, it should be connected the the internal steel-platform and roof to form a spatial structure. To achieve the overall design requirements, the carrying capacity of frame column, the joint force transmission way and the corresponding node constraint control should be considered.
Keywords:new node; model test; failure characteristics; arc contact; energy dissipation
