Size Effect on the Compressive Strength of Laminated Bamboo Lumber
Publication: Journal of Materials in Civil Engineering
Volume 33, Issue 7
Abstract
The size effect on the axial compressive performance of laminated bamboo lumber is studied through compression tests on three groups of short columns with different heights and section sizes. The failure modes, bearing capacity, strain distribution, and deformation capacity were analyzed. Based on the test results, three groups of stress-strain models of laminated bamboo lumber with different sizes are presented. The simulated results were in good agreement with the test results. The slope method and the parameter method were used to calculate the size effect coefficient and the results showed that the linear regression parameter analysis method is more efficient for analyzing the size effect. It is concluded that the size effect coefficients of compressive strength, ultimate load, elastic modulus, ductility, and compressibility are 0.043 (), 0.6676 (), 0.064 (), 0.0529 (), and 0.133 (), respectively.
