Influence of truss rod damage on prestressed concrete

The prestressed concrete cable-stayed truss T- frame bridge is a novel type and complex structure. Truss damage is a common form of distress in this type of bridge. For studying the mechanical properties of truss members under the condition of the truss rod, a finite element model is established for analyzing the damage or failure of the truss rod.

Four of the cable stays (each with 156 strands) are the largest in the world for a cable-stayed bridge. The first stay was stressed on July 20, 2006 and the last of the 20 stays was stressed in December. It's also the largest single project ever undertaken by ODOT, being bid at $220 million in 2002.

Recent Advancements in Prestressed Concrete Bridges

Jun 02,  · Development of External Prestressing . One of the significant advancements in the recent evolution of prestressed concrete is the increasing use of external prestressing.Externally prestressed concrete bridges are designed with tendons placed outside the section but remain within the bounds of the cross-section (Figure 2). This concept has become extremely popular for medium and long-span bridges.

CABLE BRIDGE - Transportation - S 10th Ave, Pasco, WA

At the time, the bridge was thought to be the first in the United States to use a 'cable-stayed' design and is constructed almost entirely of prestressed concrete. The Cable Bridge, from the time of its opening (1978), has proved to be a popular landmark in the Tri-City area, so much so it has become an unofficial symbol of the area.
