斜交薄壁箱梁的空间受力分析

Space Structural Analysis for Skew Thin—Walled Box Girders

本文采用有限分段变换法对斜交薄壁箱梁进行了空间受力分析。考虑到截面畸变中心、扭转中心,弯曲中心及翅曲零点的影响,并结合料交箱梁有机玻璃模型的实验,对该方法的可靠性及适用范围作出了评价,同时还对该方法编制了计算机程序SBCP—1,可在小型IBM计算机上完成。

A finite segmental transformation method is presented in this paper. The effect of bend-ing, torsion、and distortion centres and the warping zero point are considered. Having compared with htemeasured results of the model experiments, the accuracy of the proposed method is demonstrated.
