FRICTION COEFFICIENT for base isolation
FRICTION COEFFICIENT for base isolation
(OP)
hi to all,
can anyone tell me if american seismic codes or standards limit the maximum coefficient of friction in sliding devices employed for base isolation?
the NEHERP guidelines for buildings FEMA 273-274, 302-303
do not seem to limit the coeff. of friction, neither they prescribe any periodic lubrication
am i right?
and the AASHTO?
thanks

RE: FRICTION COEFFICIENT for base isolation
Other useful reference would be Structural Dynamics by Gary Hart which has a nice treatment of seismic isolation.
Any papers written by James Kelly would be helpful as would Kelly's book on Seismic Isolation. I beleive this was in cooperation with Farzad Naiem, and so Naiem has a new chapter in his second edition of the Seismic Design Handbook on isolation.
