[摘要] 結(jié)合工程實(shí)例，對(duì)較為復(fù)雜的新型鋼結(jié)構(gòu)體系進(jìn)行了計(jì)算分析。豎向鋼桁架為結(jié)構(gòu)的豎向支撐體系，頂層大跨的平面桁架與豎向的鋼桁架相連，形成主要的抗側(cè)力體系。主體鋼桁架下面，中間斜樓梯、斜電梯的兩側(cè)，懸吊布置三個(gè)形狀各異的吊艙。在分析和設(shè)計(jì)過程中充分考慮了主體框架和吊艙各自的力學(xué)特征以及它們之間的相互作用，明確合理的傳力路徑。

Abstract: According to the real project, we analyse the new complicated steel structure system. The main lateral structural support system is made up of the vertical truss as the vertical support system and the horizontal truss. Three anomalistic balls are suspended under the main steel truss between the stair and the gradient lift. The mutual force between the main frame and the suspension balls is concerned in the calculation model. The logical force path is expatiated.
Keywords: gradient lift; gradient stair; steel truss, suspension ball; plastic hinge
