Numerical Analysis for Geometry Nonlinear Characters of Laminated Box Beam Columns

Article Preview

Abstract:

In the action of bending load and axial compression, the deflection of the beam presents character of geometry nonlinear. For the thin-walled carbon fiber laminated box beam column, the beam deflections not only relate with load but also with the ply angle of layer, span width ratio. By using the method of numerical, this paper analyzed and summarized the beam deflection variation with the span width ratio, ply angle, the axial compression ratio for the simply supported laminated box beam column under the axial compression and bending load.
