DYWIDAG Bar Tendons preserve a Piece of History: Reinforcement of the Basilica of Maxentius on Rome’s Forum Romanum

The Basilica of Maxentius is located on the border of Rome’s Forum Romanum. The structure was built on an area that originally measured 100 x 70m from approximately 307 to 313 AD and was thus one of the largest buildings in the Forum. Today, only the northern aisle of the Basilica still exists.

Recently, it became necessary to stabilize the Basilica of Maxentius. For this purpose, the vertical masonry was braced using 165 St 1050, 40mm Ø DYWIDAG Post-Tensioning Bars. The individual DYWIDAG Bar Tendons are 6m long and were joined using couplers. Specially designed AISI 316 steel anchor plates were used for this project.

The DYWIDAG Bar Tendons were installed to a height of more than 30m and tensioned in stages, with the movements of the masonry being simultaneously and continuously measured. The tensioning bars were hot dip galvanized and are permanently protected from corrosion by heat shrink sleeves.

The DYWIDAG Bar Tendons that were used had a total length of approximately 1,000m. DYWIT Italy not only supplied the necessary bar tendons including accessories, but also provided the equipment needed for the stressing work and on-site technical assistance.
