This report concerns the monitoring of a portion of the Bonnet Carre Spillway Bridge during an extreme overload. On Tuesday, November 5, 2002, Tulane University was requested to monitoring strain at the bottom flange of two adjacent prestressed girders before, during, and after the passing of the overload. On Thursday, November 7, this request was modified to include monitoring of strain in the following regions of interest: (a) Positive moment region on three adjacent girders; (b) Negative moment region over the pile cap at the center of the bridge width; (c) Positive and negative moment region on one pile cap; (d) Shear region on one pile cap; and (e) Compression region on one square pile. After the monitoring was performed, efforts were made to quantify and reduce the error that may have arisen from necessary compromises. These efforts included additional laboratory testing described in this report.
