Experimental investigation of composite materials for sliding friction dampers: data, plots, photos and videos of the tests

Folder DATA This folder contains the data acquired by testing the friction pads M1, M2, M3, M4 and M5 under the following loading protocols: Linear static loading (M); Cyclic loading with constant amplitude (CA); Cyclic loading with decreasing amplitude at low rate (DA); Cyclic loading with increasing amplitude at low rate (IA); Cyclic loading with increasing amplitude at moderate rate (IA-H); Cyclic loading with increasing amplitude at high rate (IA-HH); Pulse-like loading protocol (PL); Mainshock-aftershock protocol (MS-AS): mainshock (MS), first aftershock (AS1) and second aftershock (AS2). The data include: Time: time (unit: second); F: axial force experienced by the sliding friction damper (unit: kN); N_bolt: bolt preload (unit: kN); mu: friction coefficient of the considered pad (unit: dimensionless); delta: axial displacement experienced by the sliding friction damper (unit: mm); Cum. delta: total cumulative displacement experienced by the sliding friction damper (unit: mm); Cum. E: total cumulative energy dissipated by the sliding friction damper (unit: kJ); max Tin: maximum temperature tracked close to the sliding interface (unit: Celsius); Tout: temperature tracked at the surface of the inner slotted plate (unit: Celsius). The data are organized as follows: Folder T100 This folder contains the data acquired under the linear static loading protocol (M) for a tightening torque of 100 Nm. Each EXCEL file T100_M_Y saved in the folder T100 contains the data obtained by testing the friction pad Y (Y = M1, M2, M3, M4, M5) under the loading protocol M. Folder T200 This folder contains the data acquired under the linear static loading protocol (M) for a tightening torque of 200 Nm. Each EXCEL file T200_M_Y saved in the folder T200 contains the data obtained by testing the friction pad Y (Y = M1, M2, M3, M4, M5) under the loading protocol M. Folder Fs150 This folder contains the data acquired for an expected slip load of 150 kN. Each subfolder Fs150_X contains the data obtained under the loading protocol X (X = M, CA, DA, IA, IA-H). Each EXCEL file Fs150_X_Y saved in the subfolder Fs150_X contains the data obtained by testing the friction pad Y (Y = M1, M2, M3, M4, M5) under the loading protocol X. Folder Fs300 This folder contains the data acquired for an expected slip load of 300 kN. Each subfolder Fs300_X contains the data obtained under the loading protocol X (X = M, CA, DA, IA, IA-H, IA-HH, PL, MS, AS1, AS2). Each EXCEL file Fs300_X_Y saved in the su
