BOLTED TIMBER-STEEL CONNECTIONS WITH SLOTTED HOLES

Evelyne Toussaint

Résumé

An experimental program is performed on steel-timber bolted connections using slotted-in steel plate or two lateral steel plates. The steel plates have circular holes alone or combined with slotted holes. The idea is to evaluate the influence of the slotted holes on the mechanical performance of the tested connections. The slotted holes are used to give a free relative displacement between the fasteners to limit the stresses dues to geometrical variation (swelling and shrinkage) of wood in the direction perpendicular to grain. The results are observed considering the moment-rotation curves of all the specimens. Besides, DIC (Digital Image Correlation) technic is used at the surface of the specimen to observe the deformation of the specimen and to obtain the evolution of the centre of rotation of each connection. The results show that the slotted holes are promising solutions as they give higher strength compared to that of circular holes in the case of slotted-in steel plates.
