EXPERIMENTAL RESEARCH ON AXIAL COMPRESSIVE PERFORMANCE OF COMPOSITE SHORT COLUMN WITH WOOD CORE REINFORCED BY GFRP WEBS

Abstract

Abstract: The composite short column with paulownia wood core reinforced by GFRP webs is prepared through vacuum assisted resin infusion. The composite column has the characteristics of high specific strength, high specific stiffness, good corrosion resistance and ductility etc.. Composite columns were tested under axial compression, the mechanical properties of the composite columns with different lattice forms and different fiber layers are studied. Based on the elastic analysis method, the theoretical value is calculated, which is consistent with test result.

Key words: wood core composite column, lattice webs, axial compression, failure mode, bearing capacity
