摘要
本文采用三次和一次样条相结合的样条子域法对等高度变截面连续直箱梁桥进行静力分析。该方法精度高计算量少,解决问题面广。对于工程中常见的单箱单室、单箱双室等直箱梁桥可用微机方便地分析。
The new spline snbdomain method is advanced to analysis the straight continuous box girder bridge with variable crosseetion but constant height by this paper. This method based on the B_1,B_3 spline and the variation principle, possesses high approach accuracy, less calculation, and suit for analysis of the bridge with various support condition under various load condition. Especially for common box girder adopted in engineering design, its static analysis may be performed in microcompufer.
