Design for Whipping Pipe Impact on Reinforced Concrete Panels
This paper describes determination of local and overall effects on reinforced concrete panels due to whipping pipe impact in postulated pipe break events. Local damage includes the prediction...
Sensitivity of Peak Dynamic Responses to Input Factors
Responses have been calculated for the Zion Unit 1 plant, using the SSMRP computer code SMACS, as part of the seismic probabilistic risk assessment performed by the Seismic Safety Margins...
The Response of Steel Containment Models to Internal Pressurization
To obtain insight and data on the response of containment vessels subjected to beyond design basis accidents, four 1/32 scale steel containment models have been subjected to internal overpressurization,...
Piping Analysis: A Flexibility Approach
Design for the vertical and horizontal accelerations associated with a seismic event coupled with low allowable loads on equipment are two primary contributors to the current situation....
Bayesian Procedure for Evaluation of Containment Capability
The functional requirements of a steel or concrete containment is to maintain the structural integrity as well as the leak-tight integrity of its pressure boundary under specified design...
Determination of Containment Vessel Ultimate Capacity Using Nonlinear Finite Element Analysis
Analysis of steel containment vessels is normally performed using linear elastic solutions with allowable stresses specified by applicable design codes. This method gives little indication...
Update on Impact Effects in Nuclear Plants Part II?Review of Pipe Whip Impact
Current regulations require that pipe breaks be postulated in high-energy lines and measures be taken to prevent consequent damage to essential structures and systems. The paper addressed...
Allen-McColloch Pipeline Computer Based Control System
The Allen McColloch Pipeline (AMP) was designed to deliver 416 cfs of treated water from the Metropolitan Water District of Southern California's Diemer Water Treatment Plant...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Design and Performance of Buried Fiberglass Pipes ? A New Perspective
The buried performance of fiberglass pipes was the subject of a comprehensive and multifaceted research program carried out in 1982 and 1983. Instrumentation, capable of accurately tracing...
Design of Thin Wall Reinforced Concrete Pipe Using Dimension Ratio (DR)
Dimension Ratio is defined as the ratio of the internal pipe diameter to the pipe wall thickness. The Caltrans culvert research leading to the development and use of the Dimension Ratio...
Performance of Low Stiffness Plastic Pipe in Stiff Soils
Large diameter pipe made from ductile plastics, such as polyvinyl chloride (PVC), polypropylene (PP) and high density polyethylene (HDPE) can be effectively utilized in subsurface installations...
Design Criteria for Buried Flexible Pipe
A modified CANDE program was used to analyze a full factorial set of design parameters for buried, large diameter high density polyethylene profile-wall pipe. A new pipe subroutine was...
Importance of Pipe Soil Stiffness Ratio in Plastic Pipe Design
In this paper, the finite element method of analysis is used to study the effect of pipe-soil stiffness ratio on axial forces, bending moments, and deflection of pipes of varying stiffness....
Centrifugal Modeling of Pile Foundations
Modeling of pile foundations in a centrifuge, where the self weight induced stresses in the soil are simulated by elevated gravity loading, is described. Hollow pipe piles in a stiff clay...
Shaft Capacity of Driven Pipe Piles in Clay
A compilation of axial load test records for driven pipe piles in clay published by the American Petroleum Institute is analysed to yield new criteria for skin friction and pile scale...
A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...
Consolidation Performance of Soft Clays: Part 2. Predictions
The simplified version of the model described in Part 1 was used to predict the short-term performance of the St. Alban test fill. The long-term predictive capability of the model was...
Consolidation by Sand Drain in Anisotropic Ground
The author reduces Biot's equations of consolidation into a single governing equation with the excess pore water pressure as the only unknown function and derives the theory...
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
