PTFE Seismic Coefficient of Friction

PTFE Seismic Coefficient of Friction

PTFE Seismic Coefficient of Friction

(OP)
Hello All,

I'm looking into an abutment that's supporting a bridge through PTFE disks at the bearings. AASHTO gives us the disk's coefficient of friction at the service limit state (under very slow movement), but refers to the seismic loop diagram for the seismic coefficient of friction. I'm wondering, is there a typical value for the PTFE coefficient of friction that can be used when looking at the superstructure lateral load contribution under seismic loading?

Thanks!
