“…No surface treatment was performed to the aluminum splice plate. Note that, although aluminum was selected as a material for the splice plates in this paper to realize smooth sliding, 11 other materials can be used as far as smooth sliding is obtained. The grade of all the steel tubes was SS400 (JIS G3101).…”

This note examines the feasibility of an improved slotted bolted connection for timber moment frames. In the present connection, steel tubes are inserted into drill holes in glulam, and the steel tubes are fixed to the glulam with resin injection. Aluminum splice plates with curved slots, or curved elongated holes, are fastened mechanically by using high strength bolts that go through the steel tubes. Since the compression due to bolt tension is fully supported by the steel tubes, reduction of bolt tension due to shrinkage of glulam can be avoided. The use of slotted aluminum splice plates allows stable energy dissipation due to smooth sliding between the aluminum splice plates and the end surfaces of the steel tubes within the specified range of rotation angle. Through quasistatic cyclic loading tests of two connection specimens, it was demonstrated that stable and nearly rigid-plastic hysteresis loops were obtained whose equivalent viscous damping ratio was more than 30 % in the ranges of rotation angle close to or over 1/50 radian. Although further improvement is necessary, the experimental results demonstrate the feasibility and potential of the present connection.

“…Among the many other materials such brass [10] [11], bronze alloy [12][13] and aluminum alloy [14] [15], specially designed brake pads have been recognized as a high performance frictional material for friction dampers [16]. However, the composition and mechanical properties of brake pads vary from manufacturer to manufacturer, and test results have shown that the friction coefficient might be subjected to a complicated dependency on a variety of factors, including the clamping pressure, loading velocity and cumulative heat [17].…”
