Kerto-Laminated Vaneer Lumber Truss
Kerto laminated veneer lumber (LVL) truss is a long span roof header. Members of Kerto-LVL-truss are all constructed of two separate Kerto-LVL-members which are jointed together with twin grip plates, a joint method especially developed for this purpose. The function of twin grip plates is based on the nail joint between a steel plate and the Kerto-LVL-member. The strength and rigidity tests of the twin grip plate joints have been carried out at the Helsinki University of Technology in the Department of Civil Engineering as a Masters Thesis. The joints were found to be very rigid under tests with service loads. The fracture is ductile due to yielding of nails before the fracture. Besides bending rigidity of twin grip joints decreases when rotation increases. Thus twin grip plates are suitable joints for Kerto-LVL-trusses.
