计入剪切变形的基桩屈曲稳定分析
Buckling stability analysis of pile considering lateral shear deformation
摘要
Abstract
Two buckling stability analysis equations are established in two specific cases.One rigid equations of beam elements considering the P-△ effect and the lateral shear deformation produced by lateral load to simulate the working of pile.Procedures for critical buckling analysis of pile by finite pole element method.Case analysis of critical buckling analysis of pile is done.Both shear deformation and boundary condition of the pile tip,has extremely small effect on buckling stability of pile.While boundary condition of the pile block and coefficient of soil reaction,has remarkable effect on buckling stability of pile.关键词
