EVALUATION OF SHEAR STIFFNESS OF STEEL-TIMBER CONNECTIONS USING HIGH-STRENGTH BOLTS AND STEEL PIPES IN DIRECTION PERPENDICULAR TO GRAIN

Abstract

The shear stiffness of steel-timber connections using high-strength bolt and steel pipes in direction perpendicular to grain was analytically and experimentally evaluated. The initial shear stiffness obtained by splitting tests of the connections by the authors was 3-4 times greater than embedment stiffness evaluated by using existing equations. Finite element analyses were conducted and it was found that the difference maybe generated by the embedment of washer and friction between the steel plate and timber.
