AMERICAN PRACTICES IN THE DESIGN OF PRESTRESSED CONCRETE CONTAINMENT STRUCTURES

PCI Journal, 1968
In the last two years the nuclear power industry has been successful in capturing approximately 50 percent of new electrical generating capacity. Financial and business newspapers and periodicals have provided extensive coverage of the tremendous upswing of power plant orders going to producers of uranium-fueled, water-cooled and moderated nuclear ...

Prestress System for Nuclear Concrete Containment Domes

Journal of the Power Division, 1974
Nuclear concrete containments are prestressed with large force tendons in order to provide sufficient compression to counteract the tension forces induced during a postulated loss-of-coolant accident. Because of the nature of dome configurations, tendon arrangements require some special considerations with respect to their effectiveness and ...

Prestressed Concrete Nuclear Plant Containment Structures

PCI Journal, 1976
A lthough prestressed concrete nuclear plant containment structures came into prominence only about 10 years ago, nevertheless, their design and construction features have undergone rapid development. So much so, that in this short time period we can identify three generations of evolution in containment design and construction practice.

Strength monitoring of a prestressed concrete containment with grouted tendons

Nuclear Engineering and Design, 2002
Existing containments are all required to be checked for their strength periodically through inservice inspection programs. In China, all the containment prestress tendons are protected by cement grouting, except the sampling tendons for testing.

Dynamic behaviour of frames containing prestressed concrete beams

Magazine of Concrete Research, 2001
Results from small scale models of frames containing prestressed concrete beams, tested by a shake table simulating earthquake forces, are presented. The dynamic response analysis of such frames are described. A comparison between tests and analysis is made.

Capability of a prestressed concrete containment for internal pressure load

Nuclear Engineering and Design, 1984
Abstract This paper presents a study for a PWR prestressed concrete containment which determines a realistic lower bound internal pressure where no structural failure is anticipated. The paper indicates the analytical method used, the actual material properties investigated, and the failure criteria selected for the material stresses and strains.

Shear in prestressed concrete beams containing steel fibres

International Journal of Cement Composites and Lightweight Concrete, 1987
Abstract The results of some 36 shear tests carried out on simply supported rectangular prestressed concrete beams, containing steel fibres as web reinforcement are presented and discussed. The parameters varied were the fibre content, the shear-span effective depth ratio (a/d) and the type and extent of prestressing.

Sensitivity analysis of numerical model of prestressed concrete containment

Nuclear Engineering and Design, 2015
Abstract Safety is always the main consideration in the design of containment of nuclear power plant. However, efficiency of the design process should be also taken into consideration. Despite the advances in computational abilities in recent years, simplified analyses may be found useful for preliminary scoping or trade studies.

Observations on analysis, testing and failure of prestressed concrete containments

Nuclear Engineering and Design, 1984
Abstract The paper reviews the mechanics which indicate that a bursting failure with large energy release is the failure mechanism to be expected from ductile lined containment structures pressurized to failure. It reviews a study which shows that, because of leakage, this is not the case for unlined prestressed containments.

Prediction model of long-term prestress loss interaction for prestressed concrete containment vessels

Archives of Civil and Mechanical Engineering, 2017
Conventional methods disregard the interaction effects between concrete creep and tendon relaxation to evaluate the long-term prestressed losses. The main contribution of this paper is to present a new method to compute this interaction for prestressed concrete containment vessels.
