A comparative study of compression behaviors of cross-laminated timber and glued-laminated timber columns

Abstract This work investigated the different axial compression behaviors of cross-laminated timber columns (CLTCs) and control glued-laminated timber columns (GLTCs). The average compression modulus of elasticity (MOE) and strength values of the CLTCs were lower than those of the control GLTCs and appeared to be dependent on the area ratio in the axial direction. The column length had different effects on the compression behaviors of CLTCs and GLTCs, and compared with the GLTCs, the CLTCs exhibited enhanced ductility and energy absorption properties due to the cross-lamination. Of the three models developed in this work, model I is recommended for GLTCs and model II for CLTCs.
