EMERGENCY MONITORING OF THE WILLIAMSBURG BRIDGE, NEW YORK CITY
This paper presents the NDT methods and instrumentation used for monitoring of a major crack that developed in the masonry pedestal of a tower of the Williamsburg Bridge. This paper will explain the factors which contributed to the cracking of the pedestal, as well as the reason for monitoring the crack and the tower. Until a permanent repair or replacement of the "pinned" link on the top of the tower can be made, a monitoring program has been implemented. The following are monitored; the variation of the crack width, the variation of the stress in the steel structure portion of the tower, and tower verticality. The following methods (procedure, instruments) are used; electrical resistance strain gages for static and dynamic readings, dial gauge indicators, and optical instrumentation.
