Federal Building, San Francisco

BUILDING STRUCTURAL HEALTH MONITORING PROJECT

Location: San Francisco, California
Structure type: Building
Purpose: Previously instrumented building that needed a structural health monitoring system to bypass current system in order to provide remote access to data in real-time. Has been instrumented since 2002 while providing continuous data analysis.
Channel Count: 32 channels
Sensor type(s): Accelerometers

Overview: The Federal Building is a 24-story steel frame building located in a seismically active area. Following a seismic retrofit, the building owner needed a monitoring system that would facilitate rapid assessment of the building's structural health and assist in making informed decisions regarding post-earthquake building occupancy. Digitexx installed a 32-channel, 24-bit RTMS-2001 system that was capable of complex structural health monitoring. Since its installation, this system has recorded a number of small to moderate earthquakes.
