[摘要] 结合工程实例，对较为复杂的新型钢结构体系进行了计算分析。竖向钢桁架为结构的竖向支撑体系，顶层大跨的平面桁架与竖向的钢桁架相连，形成主要的抗侧力体系。主体钢桁架下面，中间斜楼梯、斜电梯的两侧，悬吊布置三个形状各异的吊舱。在分析和设计过程中充分考虑了主体框架和吊舱各自的力学特征以及它们之间的相互作用，明确合理的传力路径。

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
