Torsion in plain and prestressed concrete beams containing polypropylene fibres
Magazine of Concrete Research, 1984Synopsis Torsion tests on 23 plain and prestressed concrete beams containing polypropylene fibres are presented and discussed. The addition of these fibres to concrete is shown to improve the post-peak ductility, though there is no change in the ultimatc torsional capacity of the beams tested.

Analysis and application of prestressed concrete reactor vessels for LMFBR containment
Nuclear Engineering and Design, 1978Abstract An analytical model of a prestressed concrete reactor vessel (PCRV) for LMFBR and the associated finite element computer code, involving an explicit time integration procedure, is described. The model is axisymmetric and includes simulations of the tensile cracking of concrete, the reinforcement, and a prestressing capability.

TEMPERATURE STRESSES IN PRESTRESSED CONCRETE WALLS OF CONTAINMENT STRUCTURES
PCI Journal, 1974The walls of prestressed concrete tanks and containment structures are subject frequently to severe temperature differentials between the outside and inside surfaces. Thus, it becomes important that the temperature-induced moments and stresses in such structures be accurately determined so that the compensating prestressing force can be optimally ...

Study on the Prestressing Effect in Reinforced Concrete Containment by Using ANSYS
Volume 2: Plant Systems, Construction, Structures and Components; Next Generation Reactors and Advanced Reactors, 2013Prestressed reinforced concrete containment is an important part among the safety-related buildings, and the presressing technology is widely used in containment construction which is best suited to the cylindrical-type containment topped by a dome. It has been recognized that traditional methods for analysis of containment prestressing system have ...

Prestressed Time-Limited Aging Analyses of Concrete Containment Structure
Volume 1: Operations and Maintenance, Engineering, Modifications, Life Extension, Life Cycle and Balance of Plant; I&C, Digital Controls, and Influence of Human Factors, 2017For prestressed concrete containment structure, prestress loss is a key factor that affects the performance of containment structure. Therefore, prestressed time-limited aging analysis (TLAA) is essential for containment structures. The main objective of prestressed TLAA is to assess the safety of containment structures after prestress loss occurred ...

Preliminary Analysis of Pressure Bearing Capacity for a Typical Prestressed Concrete Containment
Volume 2: Plant Systems, Structures, Components and Materials, 2017In this paper, the pressure bearing capacity of containment is analyzed to support the severe accident management guidelines development. The finite element model of containment is established. The concrete, the steel liner, and the prestressed tendons models are developed. The ordinary steel bars are in an integrated model with concrete.
