Strength tests of glulam beams with quadratic holes - Test report

Danielsson, Henrik LU (2008) In Report TVSM TVSM-7153.
Abstract
This report deals with strength tests of glulam beams with quadratic

holes with rounded corners. A total of 36 individual tests were

carried out, divided into nine test series with four nominally equal

tests in each test series. There were four para\-meters varied

within these test series: beam size, bending moment to shear force

ratio, material strength class and also hole placement with respect

to the height of the beam. The latter parameter seems to never have

been investigated before since all previously performed tests found

in the literature have been carried out on beams with holes placed

centrically in the beam height direction. The test results... (More)

centrically in the beam height direction. The test results indicate

a strong size effect. The influence of eccentric placement of the

hole on the crack load was found to be small. (Less)
