The paper describes an innovative design concept for a LMFBR Core Support Structure. A hanging Core Support Structure is described and analyzed. The design offers inherent safety features,...
A Computer Integrated Engineering System for Nuclear Plant Design
The design, construction, and licensing of nuclear power facilities is a long and complicated process which can span a time period of over ten years. This tremendous lead time to plant...
An Estimate and Evaluation of Design Error Effects on Nuclear Power Plant Design Adequacy
An estimate by the author is found of typical error levels contained in Structural-Mechanical-Civil Design and Stress Reports. Based on the original analysis performed to demonstrate design...
Slurry Pipeline Control Systems
The paper documents the La Perla-Hercules pipeline and its control system. This eight and fourteen-inch, 382-kilometer iron ore concentrate slurry pipeline was commissioned in June of...
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...
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....
The Present Status of Application of the Plastic Concepts in Structural Design
The different approaches of recognizing plastic behavior in the design of steel structures are reviewed and the design requirements that assure successful utilization of this behavior...
Computer-Automated Limit-States-Design of Steel Frameworks
The paper concerns the computer-automated synthesis of minimum-weight planar steel frameworks. For any number of applied loading cases, the design of the structure may be constrained by...
Reliability-Based LRFD for Transmission Structures
A simple reliability-based Load and Resistance Factor Design (LRFD) method is proposed for the structural design of electric transmission lines. With the proposed method, the designer...
Plastic Design Requirements of the AISC Proposed LRFD Specification
The American Institute of Steel Construction proposed LRFD Specification (1) has recently completed a one year period of trial use and review. This paper discusses the background of the...
Probing the Past
In Denver, Colorado, 12 buildings of an old abandoned brewery complex were to be renovated into a 270,000 sq ft shopping, entertainment and restaurant complex. Rather than conduct a thorough...
Limiting Tip and Side Resistance: Fact or Fallacy?
The tip and side resistances of deep foundations do not reach a limit at a critical depth; instead, they increase with depth. For the tip, the rate of increase decreases with depth. For...
Pile Foundation Design Using Pile Driving Analyzer
