The entire bridge deck, including the swing bridge, is made of prestressed concrete. The main bridge was built by incremental launching, with a unit length of m corresponding to 1/3 of the regular span. With respect to this construction procedure, its depth is m, corresponding to 1/ of the regular span.

PRESTRESSED CONCRETE Prestressed concrete, invented by Eugene Frevssinet in is a method for overcoming concrete’’s natural weakness in tension.

It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.

It can be accomplished in three ways: pre- tensioned concrete, and. Prestressed Concrete Members Mohsen Shahawy, Ph.D., P.E. President Structures Design and Rehabilitation, Inc.

Takizawachlorides. The process of assessment of fire-damaged concrete bridge with prestressed hollow core plate girders was provided.

According to the assessment results, methods of repair and strengthening were presented for different fire-damaged level of prestressed hollow core plate by: 1. Traditional methods used to repair prestressed concrete (PC) girders subjected to impact damage due to overheight vehicles include strand splicing and external posttensioning.

These methods have proven to be partially satisfactory in restoring the damaged girder’s ultimate strength. Manual for the Evaluation and Repair of Precast, Prestressed Concrete Bridge Products addresses the repair of damage to, or non-conformances in, bridge contains diagrams of the various types of cracks, chips, voids, missing bars and other issues that occur from time to time in manufacture.

If it is considered that there is no concern about any deterioration, flexural strength of prestressed concrete bridges may be obtained from Equation (1). File Size: KB.repair techniques for impact damaged prestressed bridge girders: strand splices, fiber reinforced polymer (FRP) overlays, and fabric reinforced cementitious matrix (FRCM) overlays.

The flexural strength of four AASHTO Type III girders, three of which were intentionally damaged and repaired, was evaluated.
