Resumé

This report presents an evaluation of effectiveness of repair methods on two structures along the I-40 corridor in San Bernardino County California. A modal test was conducted on each bridge before and after the repair work was finished. After each test, the modal parameters were extracted and the bridge superstructure was evaluated using systems identification and nondestructive damage location techniques. The modal analysis delivered changes in frequencies and mode shapes. Changes in the material and structural properties of the superstructure were provided through the systems identification and damage location techniques. A summary of project results are presented in the report.
