［摘要］大連國際會(huì)議中心屋蓋采用管桁架空間結(jié)構(gòu)?？紤]屋面板布置的不規(guī)則性，桁架節(jié)點(diǎn)為剛性節(jié)點(diǎn)，采光部分用相貫管節(jié)點(diǎn)，其余部分盡量采用焊接球節(jié)點(diǎn)，個(gè)別形狀復(fù)雜的節(jié)點(diǎn)采用鑄鋼節(jié)點(diǎn)或組合節(jié)點(diǎn)。由于屋蓋支座分布不均勻，造成屋蓋周邊出現(xiàn)不規(guī)則的懸挑，變形很大。為節(jié)約鋼材和建筑的美觀，屋蓋周邊與幕墻柱相連，采用相容性分析，幕墻柱參與支承屋蓋的作用，大大減小屋蓋撓度。支座下部采用鋼管組合柱支承，支座為球鉸節(jié)點(diǎn)，限制位移、放松轉(zhuǎn)動(dòng)，滿足設(shè)計(jì)要求。

Abstract:The pipe truss structure is used in the roof of Dalian International Conference Center. Considering the house panels are arranged irregularly, truss joints are rigid. Intersecting tubular joints are used for the lighting part, and welding ball nodes are used for the rest as far as possible. Cast steel nodes or combination nodes are adopted for several nodes with complex shape. Due to the uneven distribution of roof supports, the irregular cantilever and the large deformation are caused in the-surrounding of the roof. In order to save steel and format the beautiful architecture, compatibility analysis was used between the-roof structure and the peripheral surface frame plate. Curtain wall columns are involved in supporting truss to reduce the-deflection-of the roof greatly. The-combinations of steel pipe column-are used under the support. Ball bearing hinge nodes are used, which can limit the displacement and relax the rotation.
Keywords:irregular large cantilevered; compatibility analysis; translation support；rotating support
