2. Bridge Design
This paper reports on a non-linear analysis of a bridge supported on sliding bearings with elastomeric restoring spring and viscous dampers. Results were verified with shake table tests.

This specification, prepared jointly by TY Lin and Imbsen Associates, describes the requirements for the viscous dampers to be used in the retrofit of the Golden Gate Bridge. The specification includes wind excitation as well as seismic, and also describes testing requirements.
Light poles at Rich Stadium in Orchard Park, N.Y., were showing incipient failure of their hold-down bolts, due to wind excitation. This paper describes the measures used to alleviate this problem, including the addition of viscous dampers between the stadium structure and a point around one third up on the light poles.
