【摘要】 超高层钢筋混凝土简体结构是高层建筑结构的发展方向之一。筒体结构由于侧向刚度大，整体性好，传力明确，空间布置灵活，非常适用于高层超高层办公、旅馆和综合性建筑，是应用最广泛、最有前景的结构形式之一。本论文研究筒体结构的静力及动力计算方法，寻求一种能够很好解决筒体结构分析问题的方法，为筒体结构分析探索出一种计算准确，在实际应用中经济、实用切实可行的方法。本文着重进行了两个方面的研究：筒体结构模型的静力弹性新的分析方法，筒体结构模型的地震反应新的分析方法。在前人研究的基础上推导了新型的单元并利用QR法对筒体结构进行分析，建立该结构的静力分析与动力分析的新计算格式，并用C语言编制计算程序，计算了一些例题并与有限元方法进行比较。结果表明，该方法未知量少，精度高，计算简便，适用性强，且程序简单，是集有限元法和样条函数法优点于一身的一种经济有效的计算方法。本文不仅有理论意义，而且有实用价值。更多还原

【Abstract】 Reinforced concrete tubular structure is a developing structure system of high-rise building. As tubular structure has characteristics of great rigidity, superior property as a whole, clear-cut transmitting mechanism, flexible using space and so on, it is very suitable for tall and super-tall office, hotel and multi-use buildings. Two aspects are focused on: the new static elastic analysis method for tubular structure, the new dynamic analysis method for tubular structure. This paper worked out a new element based on research results, analyzed tubular structure by QR-method and set up a new computational form for static and dynamic analysis of this structure system, and wrote a corresponding program by C and calculated some examples and compared with finite element method. The results showed that QR-method boasts fewer unknown number, high precision, simple computation and strong adaptability, so it is an economical and effective computational method which has finite element method and spline function method’s advangtages. This paper is valuable not only in theory but also in practice.更多还原
