排架空间结构在水平力作用下的横向位移分析

Lateral displacement of shelf space structure under horizontal force

运用ANSYS有限元数值分析软件建立了高桩排架空间结构模型,计算分析叉桩排架在水平力作用下,各个桩基的位移沿桩长的变化规律,并与规范公式计算结果进行对比,二者的分析结果十分吻合。研究了水平力在排架中的分配系数规律,发现水平力的大小对分配系数也有一定影响。

This article establishes the model of a high-pile bent spatial structure by the finite element software of ANSYS to calculate and analyze the changes of the pile displacements along its length under horizontal forces. Comparing the results from the model with that from the normative formula, it is proves that the two are consistent with each other. At the same time, the law of the distribution coefficient about the horizontal force applied to the bent is researched, and it is found that the horizontal force also has some influence on the distribution coefficient.
