摘要
使用Ｓａｉｎｔ－Ｖｅｎａｎｔ弯曲理论，将一般截面柱体的横向弯曲问题，归结为解两个同类型的边界积分方程，并用此求得了柱体的弯曲函数和附加扭转函数．在此基础上，可用边界元法确定一般截面的弯曲中心最后为了说明方法的应用，给出了一个数值算例．
Using Saint-Venant bending theory, the lateral bending of a cylinder with a general crosssection is reduced to solving two similar boundary integral equations, from which the flexural function and additional torsion function of the cylinder are obtained. Based on the obtained results, the flexural center of the general cross-section can be determined by use of the boundary element method. Finally, as an application of the method, a numerical example is given in this paper.
