Shear strength of glued-laminated timber beams and panels
Five sizes of glued-laminated timber beams and panels
are being tested in a five-point beam-shear test
configuration to determine the shear strength capacity
and size relationships. A total of 200 matched
specimens will be tested: 100 loaded edgewise about
the strong axis and 100 loaded flatwise about the weak
axis. Statistical methods will be used to estimate mean
and coefficient of variation considering censored data,
test the significance of strength-size effect, and correlate
between beam shear and ASTM D143 block shear. At
the time this paper was written, only the beams loaded
edgewise about the strong axis were completely tested
along with the smaller-sized beams loaded about the
weak axis. This paper presents results for the strong
axis tests and a general discussion about the weak axis
tests. To date, edgewise specimens had similar sizeÛÒ
strength relationships as were observed in previous
glued-laminated shear studies.
