摘要
运用虚功原理推导出考虑接触摩擦效应时的弹性地基杆系有限单元法的单元刚度矩阵。计算分析表明:当地基比较坚硬且与梁的接触较为粗糙时,摩擦效应将会较显著地减小结构的内力与变形。
In this paper,the element stiffness matrix which considers the contact friction effect was deduced by means of virtual work principle.The computed results show that,when the subgrade is hard,and the contact of the subgrade and the beam is coarse,the internal force and deformation of the beam will be reduced considerably.
