PERFORMANCE OF A PRESTRESSED RIGID FRAME DURING REMOVAL OF COLUMN 6W FROM I93 IN BOSTON, MASSACHUSETTS. IN: PREPARING FOR CONSTRUCTION IN THE 21ST CENTURY, PROCEEDINGS OF CONSTRUCTION CONGRESS '91, SPONSORED BY THE AMERICAN SOCIETY OF CIVIL ENGINEERS IN COOPERATION WITH THE AMERICAN INSTITUTE OF MINING ENGINEERS AND THE AMERICAN ARBITRATION ASSOCIATION, CAMBRIDGE, MASSACHUSETTS, APRIL 13-16, 1991

The first phase of the suppression of Boston's Central Artery included the Early Viaduct Construction in the Central Artery North Area. This project required that Column 6W in Bent 6 of Interstate 93 be modified for a ramp to pass through it. Modifications required the removal of the lower section of Column 6W. In order to remove the column, a new support frame was constructed, prestressed, and the load transferred from the existing structure. Components of the new and existing structure were instrumented with strain gauges and dial gauges throughout this process.
