Bearing Performance of Thin-Walled Timber Composite Cee-Sections

【Objective】 The use of poplar veneer for the preparation of Cee-sections thin-walled timber structure can be used to investigate its axial compression performance and buckling deformation mode to provide the basis for the use in architecture.【Method】 Based on the cross-sectional form of cold-formed thin-walled section steel, the impact of Cee-sections thin-walled timber structure of the assemble pattern, glass fiber cloth(GFC),curling, thickness and other factors on Cee-sections thin-walled timber structure short column axial compression properties can be explored.【Result】 The result showed that the average ultimate loads of assemble pattern along the grain of veneer, assemble pattern surface layer cross grain and core layer along the grain of veneer and assemble pattern grain staggered of veneer were 12.5,14.6 and 12.97 kN respectively. The section validity of the GFC-poplar veneer composite Cee-sections thin-walled timber structure specimen is large overall, ranging from 46.46% to 50.21%. Compared assemble
