摘要
提出以３次Ｂ样条函数及最小势能原理建立的连续箱型梁桥分析的ＱＲ法。该法比有限元法及有限条法优越，很容易在微机上实现。
QR method,based on cubic B spline function and the principle of minimum total potential energy, for analysis of the continuous box girder bridges is presented.This method has great advantages over the finite element method and the finite strip method.It can be easily carried out on a microcomputer.
