Strength tests of glulam beams with quadratic holes - Test report

• 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 indicate a strong size effect. The influence of eccentric placement of the hole on the crack load was found to be small.
