About Our client

The National Science Foundation, established in 1950 by Congress, and Caltrans, with the mission of improving lives and communities through transportation, jointly supported a research project to monitor the Golden Gate Bridge.

Project Objective

Determine, using ambient vibration data, the mode shapes, associated frequencies, and damping of the bridge vibration.

Project Achievement

Over 40 years ago, instrumentation was installed on the Golden Gate Bridge. The bridge response was measured at various locations using 12 Kinemetrics Accelerometers. The signals from the accelerometers were amplified and filtered using Kinemetrics Signal Conditioners, and the recorded analog signals were digitized using the Kinemetrics electronic analog-digital converter.

With Kinemetrics instrumentation, it was possible to determine the dynamic characteristics such as natural frequencies, mode shapes, and damping ratios of the bridge, delivering critical data to researchers and operators.
