Experimental Approach of Slip Damper Cosists in Multiple Sliding Plates for Structural Seismic Control

Cyclic loading test of steel coupling beams with mid-span friction dampers and RC slabs

“…The deformations of the slab at the yield and the ultimate points were δy = Leqθy and δu = Leqθu, where the yield and ultimate rotations θy and θu were calculated by the recommended empirical equations in Eurocode 8 [28] as shown in Eqs. (11) and (12).…”

“…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].…”
