考虑切向摩阻力作用下弹性地基梁的内力计算

Calculation of elastic foundation beam considering the tangential friction

经典的Winkler地基模型忽略了基地切向摩阻力的作用,当存在明显的切向力时,对梁的内力影响较大.基于有限元思想,在考虑了切向摩阻力的条件下构建了Winkler地基模型上梁的简化计算模型,较之于原Winkler地基模型更加接近实际工程情况.

The classical Winkler foundation model ignored the base role of the tangential friction.There is the greater impact on the internal force when the significant shear force exists.Based on Finite Element Method,the simplified model of Winkler foundation model beams was constructed,on the condition that the tangential friction is taken into consideration.The calculation shows that the beam internal force of this paper is lower than that of the classical Winkler foundation model.
