QR-Methord For Seismic Response Analysis Of Tall Tubular Structure

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. It is one of the most vastly using and one of the most promising structure system. This paper studied the static, dynamic problems of tubular structure, 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. This paper is valuable not only in theory but also in practice.
