[摘要] 淄博体育场下部结构采用多层混凝土框架结构，上部结构采用大跨度钢结构罩棚。根据工程设计中的特点，对结构整体进行了有限元分析，确定合理的结构布置形式。对主体结构的异巨型框架的设计控制参数提供了解决方法。不落地钢桁架的水平推力则通过混凝土构件传递到桩基及环形布置的拉梁系统转换为构件内力。同时本文对清水混凝土预制看台板的运用进行了探讨。对体育场的结构设计及经济性控制提出了建议，为体育场结构设计提供了较好的参考资料。

Abstract: Zibo Stadium consists of multi-story concrete frames and span steel roof. According to the project's characteristic, the finite element method is applied to analyze the overall structural design in order to determine the proper structural arrangement. A method to determine the controlling parameter of different mege-frame design is introduced. The horizontal force from the steel truss that does not fall to the thrust converts to member internal force by transfering from annular ground beam to pile foundation. At the same time, the applications of fair-faced concrete precast slab are discussed. A method of the structure design of the stadium and of multiplanar CHS points is also proposed in this paper, the fact of which provides a practical reference to the design of stadium interrelated.
