FIELD: construction.
SUBSTANCE: specimen is installed in a loading device, and it is loaded till destruction. The specimen has a shape of sawn timber with opposite through-type cut-outs, the inner boundaries of which lie in one plane; with that, distance between them is at least 30 mm, and their height is at least 10 mm. The specimen is installed directly into the loading device and subject to central axial loading.
EFFECT: simpler test method of specimens at determination of ultimate strength of timber for shearing; simplifying complex test jigs, which excludes use of additional devices.
