考虑剪切变形影响的L形柱单元刚度矩阵
Stifmess Matrix for L-shaped Columns Considering Shear Deformation Effects
摘要
Abstract
In non-inertial coordinate system, the L-shaped columns element stiffness matrix was derived from the study of load-bearing capacity of the L-shaped columns considering shear deformation effects. Using the matrix, a finite element program of L-shaped column frame structure internal forces analysis was compiled. A 3-layer frame structure was calculated and a comparative study is made of the ANSYS calculation results and the calculation results of equivalent rectangular columns. Conclusions are drawn that shear deformation of the L-shaped column is greatly different from that of equivalent rectangular column; the torque of L-shaped column is influenced greatly whether considering the effects of reverse or not.关键词
