This study presents an innovative investigation into the axial compressive behavior of L-shaped aluminum alloy-timber composite (L-ATC) columns. The finite element model of L-ATC columns is established by finite element software ABAQUS, and the validity of the model was verified. The influence of critical variable parameters including Aluminum alloy model and timber type on the axial compression behavior of L-ATC columns were systematically analyzed. The results show that the failure mode of L-ATC columns is flexural buckling failure, and the ultimate bearing capacity of L-ATC column increases significantly with the increase of aluminum alloy strength and timber compressive strength. The capacity of L-ATC column of aluminum alloy model 6082-T6 is 10.07% higher than that of its model 6063-T5. The capacity of L-ATC column of northeast larch is the best, which is 35% higher than that of south pine L-ATC column.

摘要

This study presents an innovative investigation into the axial compressive behavior of L-shaped aluminum alloy-timber composite (L-ATC) columns. The finite element model of L-ATC columns is established by finite element software ABAQUS, and the validity of the model was verified. The influence of critical variable parameters including Aluminum alloy model and timber type on the axial compression behavior of L-ATC columns were systematically analyzed. The results show that the failure mode of L-ATC columns is flexural buckling failure, and the ultimate bearing capacity of L-ATC column increases significantly with the increase of aluminum alloy strength and timber compressive strength. The capacity of L-ATC column of aluminum alloy model 6082-T6 is 10.07% higher than that of its model 6063-T5. The capacity of L-ATC column of northeast larch is the best, which is 35% higher than that of south pine L-ATC column.
