ABSTRACT = {Eccentric compression tests on 15 chamfered laminated bamboo lumber (LBL) columns with a height ranging
from 600 to 3000 mm were conducted in order to study the eccentric mechanical performance. The failure of
all specimens was caused by the crack of bamboo fiber in the tensile region. When the ultimate strength was
reached, except specimens with a height of 600 mm, all other specimens could bear large deformation, showing
good ductility. The lateral displacements of the specimens under eccentric compression were approximately parabolic in the direction of column height. The ultimate bending moment of LBL columns with different slenderness
ratios under compression with the same initial eccentricity was a fixed value. The relationship between ultimate
capacity, axial displacement, lateral displacement, and slenderness ratio was analyzed based on test results. It was
found that the plane section assumption could be used to express the stress and strain distribution of chamfered
LBL columns under eccentric compression. A method for calculating the ultimate bearing capacity was proposed
using a constitutive model based on the Ramberg-Osgood relation and the empirical formula for calculating the
ultimate capacity was given on the basis of the former research as well as the test results in this paper.},
