S-BRITE Research Projects - Infrastructure Monitoring

Valmont Utility Pole Monitoring

Researchers from Purdue University's S-BRITE Center performed structural monitoring on a utility pole. No formal research had been reported on the effects of wind gusts on sign/solar panel structures near railroad tracks. Thus, this study targeted the structural response of the pole to passing railroad engines and cars, as well as natural wind loads.

Evaluating Effects of Super-Heavy Loading on US-41 Bridge over White River

Anticipating super-loads to be crossing the US-41 White River Bridge, INDOT commissioned S-BRITE Center researchers to assess the structure’s response to the heavy loads. Remote, long-term monitoring was used to collect data, which also included photographs of passing trucks whose weight triggered the system to record a picture.

Field Instrumentation for Evaluation of the I-64 Sherman Minton Bridge

In-service inspection of the Sherman Minton Bridge in southern Indiana identified cracking in the steel at several locations on the fracture-critical tie girders. Dr. Robert Connor led a group of researchers from Purdue University's S-BRITE Center in completing a Fitness for Service (FFS) evaluation of the tie girder welds on the bridge, as well as a robust, long-term, remote monitoring program where member stress, pier tilt, wind speed and direction, and ambient and steel temperature data were collected over several months.

Development and Verification of Web-based Bridge Monitoring Interface (JTRP SPR-3554)

The Virginia Ave Bridge over I-65 SB was selected for monitoring because it frequently fell victim to truck impacts owing to its relatively low clearance. S-BRITE Center researchers deployed a data acquisition system that included a datalogger, HD digital video camera, accelerometer, and cellular communications, capturing impact footage and sending immediate alerts to INDOT personnel.
