Description

Winkler model is widely used in the analysis of foundations. It is usually employed in the transfer matrix method for analysis of laterally loaded piles, but it is difficult to take account of the model in the stiffness matrix of the grid beam structures. On the other hand, since in the stiffness matrix the soil supporting beams is modeled by only concentrate springs, many elements are needed to obtain the correctness of calculated quantities. The authors present the convenient method transforming from the transfer matrix to the stiffness matrix for the analysis of the grid beam structure on the soil.
