Round Timber Joints under Tensile Loading Perpendicular to the Grain

Abstract

This paper presents the results of static tests of non-reinforced round timber bolted joints with slotted-in steel plates loaded perpendicular to the grain. This type of joints loading is particularly widespread in truss structures. Round timber test samples series were prepared to validate the behavior of a joint loaded in tension perpendicular to the grain. The joints samples were experimentally tested in the laboratory of the Faculty of Civil Engineering VŠB TU Ostrava. The test results were compared with the calculated load-carrying capacity of joints by Johansen’s yielding theory.
