The first prestressed concrete bridges First in the US: Walnut Lane Bridge, Philadelphia, 1950 Philadelphia's Walnut Lane Bridge, completed in late 1950, is considered the first major prestressed-concrete bridge in the U.S. Gustave Magnel, a Belgian engineer, and Charles Zollman, Magnel's student, designed the bridge. Prestressed concrete is structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads. Special end anchorages are fixed to the concrete; they transfer the prestressing forces into the structural element. This concept is utilized to determine the ultimate strength of prestressed beams. In the case of prestressed concrete, high-strength prestressed steel bars produce tension in a concrete member before actual loads are applied which will be balanced by . This research was aimed to develop a new vibration based non-destructive method to identify the effective prestress force in prestressed concrete box girder bridges. Ease of construction. Produced using high strength concrete with characteristic strengths of between 45 N/mm2 to 50 N/mm2 Used for the construction of highway bridges designed to MOT load requirements. It provides a lucid exposition of the theory and design of various types of prestressed concrete bridge decks such as slab tee beam continuous girder rigid frame cellular box girder and cable-stayed types conforming to the National Highway Loading Standards a prestressed concrete bridges, but have used either AASHTO Specification to design other types of bridges may be able to follow the design example, however, they will first need to familiarize themselves with the basic concepts of prestressed concrete design.

Prestressed concrete bridges: Literature. concrete arch bridges to dynamic effects on Cable Stayed bridges. Prestressed concrete decks are commonly used for bridges with spans between 25m and 450m and provide economic, durable and aesthetic solutions in most situations where bridges are needed. the prestressed tensioning process during the construction of prestressed concrete bridges must strictly follow the technical specification for construction of highway bridge and culvert (jtg/tf50-2011), and select the corresponding strength for tensioning according to the prestress value determined during the design work. The methods presented are the strutted box widening method (SBWM), which applies to concrete box girder bridges, and the strutted girder widening method (SGWM), which Prestressed concrete is internally stressed in compression, usually by high-strength steel wires or cables, to counterbalance the stresses from bending caused by loads. .
