Case Study » Williamsburg Bridge: Load Testing

Project Summary

Application Description:
A monitoring project to investigate in-situ stress-ranges and better characterize the behavior of this complex structural system.

Location:
New York, New York, USA

Products Used:
CR9000

Contributors:
Rob Connor, ATLSS Lehigh University

Contracting Agencies:
City of New York

Measured Parameters:
Strain, vibration

A significant portion of the Williamsburg Bridge project involved the replacement of the existing concrete-filled grid deck on both the south and north inner and outer roadways with a steel orthotropic deck. During controlled load tests, data were collected from 82 strain gages at sampling rates as high as 200 Hz.
