Pasadena City Hall Retrofit
Friction PendulumTM seismic isolation bearings are the centerpiece of the seismic rehabilitation of the historic Pasadena City Hal l . During construction, the original basement floor was removed and 240 Friction PendulumTM bearings were installed between the new foundation and new basement floor slab.
 
Friction PendulumTM bearings were selected over competing isolation bearings because they provided significant savings in construction costs and their relatively simpler installation details resulted in faster installation.
