[摘要] 淄博體育場下部結(jié)構(gòu)采用多層混凝土框架結(jié)構(gòu)，上部結(jié)構(gòu)采用大跨度鋼結(jié)構(gòu)罩棚。根據(jù)工程設(shè)計中的特點，對結(jié)構(gòu)整體進(jìn)行了有限元分析，確定合理的結(jié)構(gòu)布置形式。對主體結(jié)構(gòu)的異巨型框架的設(shè)計控制參數(shù)提供了解決方法。不落地鋼桁架的水平推力則通過混凝土構(gòu)件傳遞到樁基及環(huán)形布置的拉梁系統(tǒng)轉(zhuǎn)換為構(gòu)件內(nèi)力。同時本文對清水混凝土預(yù)制看臺板的運用進(jìn)行了探討。對體育場的結(jié)構(gòu)設(shè)計及經(jīng)濟(jì)性控制提出了建議，為體育場結(jié)構(gòu)設(shè)計提供了較好的參考資料。

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.
