Prestressed Concrete - an overview ScienceDirect Topics

Prestressed Concrete Prestressed concrete is a system devised to provide sufficient precompression in the concrete beam by tensioned steel wires, cables, or rods that under working conditions the concrete has no tensile stresses or the tensile stresses are so low that no visible cracking occurs. From: Comprehensive Composite Materials, 2000

Prestressed Concrete Structure - an overview ...

Prestressed concrete structures are generally designed with reference to the limit states of allowable stresses and deflection at service loads using elastic theory, and adequate ultimate load using ultimate strength theory.

Prestressed Concrete Structure - an overview ...

The main difficulty in assessing the condition of prestressed concrete structures is that failure of the prestressed members may occur as a sudden collapse without any visible warning signs. An example is the Ynys y Gwas bridge in Great Britain. It collapsed in 1985 after 32 years in service as a result of tendon corrosion, a short time after a regular visual inspection in which no evidence ...

Prestressed Concrete Bridge - an overview ScienceDirect ...

The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.

Prestressed Concrete Pipe - an overview ScienceDirect Topics

Prestressed concrete pressure pipes are covered by BS EN 639 and BS EN 642. The nominal size range is from DN 200 to 4000 and is the design internal diameter. American Standards AWWA C301-92 and C304-92 also cover large diameters. Examples of such pipe are typically DN 4000 up to 20 bar and DN 3600 up to 26 bar for North Africa.

Malcolm Joyce, in Nuclear Engineering, 2018. 10.7.3 Design Overview. The AGR design comprises a cylindrical, prestressed concrete pressure vessel containing the reactor core (fuel and moderator), 12 boilers and gas circulators (pumps). The vessel annulus is subdivided into four quadrants—each containing three boiler units and a gas circulator—with the reactor core at its centre in a steel ...
