In recent years, the use of structural members of buildings with arbitrary laminations has been increasing. When performing detailed analysis, it is necessary to appropriately consider the influence of bond slip deformation on the joint surfaces. It is desired to develop an analytical model that can perform buckling analysis.
In this paper, an analytical model for buckling analysis of a laminated column member with arbitrary number of joint surfaces, arbitrary cross-sectional shape, and arbitrary structural characteristics is proposed, and then a finite element equation is presented. The analysis example shows that by performing buckling analysis of a column member having arbitrary adhesive coefficients, the elastic buckling load can be appropriately determined, and the buckling mode can also be appropriately determined.
