As shown inside the figure, it can be seen that the magnitude on the maximum yield moment was pretty much precisely the same, even when the frequency changed. Having said that, LVDT was dropped as a setting following the 1 Hz frequency experiment, and also the experimental setting was changed. Because of this, the moment was shifted as a result of the distinction within the worth during the torque manage, however the yield moment worth was similar. Therefore, we discovered that the rotary-type damping device includes a continuous yielding moment, regardless of the excitation frequency. Figure 21a,b shows the relationship in between the moment rotation angles with the dampers plus the displacement magnitudes. The yield moments in the rotating friction dampers were all the very same, in line with exactly the same excitation frequency.Buildings 2021, 11,imental setting was changed. As a result, the moment was shifted as a consequence of the difference within the worth throughout the torque handle, but the yield moment value was similar. Consequently, we identified that the rotary-type damping device includes a continual yielding moment, no matter the excitation frequency. Figure 21a,b shows the connection amongst the moment rotation angles of the 19 of 22 dampers and the displacement magnitudes. The yield moments of the rotating friction dampers were all of the very same, in line with exactly the same excitation frequency.Buildings 2021, 11,20 ofFigure 20. Frequency dependence test benefits.

Therefore, the relationship in between the ing to the above frequency and displacement, often shifted in accordance with the tightening force in the bolt as well as the friction surface is deemed to become an incredibly essential magnitude in the tightening force in the bolt. For that reason, the relationship involving the parameter in designing the actual rotating frictio.
