QR-Methord For Analysis Of Tall Tubular Structure

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.
