摘要
主要研究巨型结构动力分析的QR法,利用QR法建立了巨型结构动力分析的新计算格式,编制了巨型结构动力时程分析的QR法程序,且利用它对一巨型结构进行了分析,计算结果与ANSYS有限元分析结果比较表明,QR法计算简便,精度高,是一种经济有效的新方法。
In this paper QR method for dymatic analysis of mega structures is studied. A new computational form on dynamic analysis of mega structures is set up by QR method. The program based on QR method is desimed for time history analysis of mega structures,and an actual model of mega structures is analysed with it. By compared with ANSYS, the results show that QR method is not only high precision and simple computation but also an economical and effective computational method.
