the shear behaviour of FRP prestressed concrete structure is still limited. This is especially true for a concrete T-beam prestressed with FRP tendons. Therefore, in this study, a non-linear finite element analysis (FEA) of concrete T-beams prestressed with carbon fibre reinforced polymer

Tendons are initialized with forces at stressing (P). Nonprestressed basic reinforcement, if any, is initialized with zero stress. The solution shown in Figure 3g is the result of the application of load, and lapse of time, with due allowance for loss of stress in prestressing, creep, and shrinkage of concrete. The solution for the given time

Prestressed concrete cylinder pipe (PCCP) is used in water and waste water systems that serve virtually every major city in North America. Under certain conditions, such as high chloride environments, the steel can depassivate, leading to corrosion. Under these conditions, cathodic protection (CP) can be used to protect the encased steel elements.

The prestress level is a key factor of prestressed concrete (PSC) beams, affecting their long-term serviceability and safety. Existing monitoring methods, however, are not effective in obtaining the force or stress of embedded tendons. This paper investigates the feasibility of elastomagnetic (EM) sensors, which have been used for external tendons, in monitoring the long-term prestress loss of

A prestressed concrete structure is defined as a building or structure where the overall integrity, stability, and security depend upon pre-stressing. Prestressed concrete structures can take many forms. Some of the most notable forms are listed below: High-rise buildings - Prestressed concrete is especially useful in high-rise buildings due

The structural behavior of prestressed concrete stress ribbon bridges is presented emphasizing the geometrical nonlinear character of the equations and the effects of creep and shrinkage of concrete. Analytical equations are integrated for the particular case of a built-in stress ribbon bridge, allowing for the determination of the effects of

Broken prestressing wire wraps are the main cause of failure in prestressed concrete cylinder pipe (PCCP) and are typically caused by corrosion, hydrogen embrittlement, overloading, high internal pressures, and manufacturing defects.

Stressing using the single-wire stressing jack. Precast concrete elements for structural engineering are efficiently produced with consistent quality at the precast concrete factory. Paul provides advice and supplies casting bed equipment for beams, roof trusses, Pi slabs, flat slabs as well as smaller bar-shaped elements and bridging joists.

compressive stress that offsets the tensile stress that the concrete compression member would otherwise experience due to self-weight and gravity loads. Prestressed concrete can be of many types based on five different criteria 1. Based on sequence of casting concrete and applying tension to the tendons a. Pre-tensioning b. Post-tensioning 2.
