This dataset contains the data obtained from a two-phase experimental program to characterize the frictional behavior of different types of polymers sliding on hot-dip galvanized steel for use in seismic isolation. All tests were performed at the John A. Blume Earthquake Engineering Center at Stanford University. Details about the testing program have been published and can be found in the following publications: Phase 1: Messina, A; Miranda, E (2022), “Frictional behavior of low-cost steel-polymer interfaces for seismic isolation,” Journal of Structural Engineering, 148 (1), doi: 10.1061/(ASCE)ST.1943-541X.0003218 Phase 2: Messina, A; Miranda, E (2022), “Characterization of the frictional behavior of steel-polymer interfaces with pronounced stick-slip effect for use in seismic isolation,” Bulletin of Earthquake Engineering, 20, 6307–6326, doi: 10.1007/s10518-022-01428-6 Overview: Messina, A; Miranda, E (2020), “Experimental characterization of low-cost steel-polymer interfaces for sliding seismic isolation bearings,” 17th World Conference on Earthquake Engineering, Sendai, Japan Each file contains the following data columns: t (s): measured time d_actuator (mm): measured displacement at the actuator d_interface (mm): measured displacement at the sliding interfaces F_normal (kN): measured normal force F_actuator (kN): measured force at the actuator F_friction (kN): friction force at each interface, computed as F_actuator/(2 x 6.9) Pressure (MPa): pressure, computed as F_normal/(area of specimen) F_friction/F_normal: normalized friction force
