Capability of LMFBR Plant Structures Beyond the Design Base
A study is presented concerning the capability of structures in a loop type Liquid Metal Fast Breeder Reactor Plant, the Clinch River Breeder Reactor Plant (CRBRP), to sustain conditions...

Reduction of Seismic Response in Breeder Plants
Thin-walled vessels to be used in the Nuclear Steam Supply Systems (NSSS) of future LMFBR's will be more sensitive to seismic excitation than their equivalents used in conventional...

A New Approach to the Design of Core Support Structures for Large LMFBR Plants
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...

Experimental Determination of Fluid-Coupling Coefficients in an Array of Hexagonal Prisms
The problem is related to the seismic analysis of fast breeder reactor cores, where the fluid trapped between the subassemblies is known to have a considerable influence on the core response....

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...

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...

As-Built Locations Through Precision Photography
This paper describes a new application of close range photogrammetry as a technique for obtaining reliable as-built locations of embedded threaded inserts in concrete structures and the...

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...

Limit State Analysis of Lattice Steel Transmission Towers
The background and present status for limit state analysis of lattice steel towers at the Bonneville Power Administration is presented. Conceptual development, a computer program, and...

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...

Testing for Salt Damage
Salts used to melt snow can contribute to deterioration of concrete structures. Various tests were used to determine the extent of damage in two structures in Rochester, N.Y. One is an...

In-Plane Composite Drains
Drainage of water from outside basement walls, behind retaining walls, or highway cut or fill slopes, has long been a problem. A common solution is the aggregate drain. Often, installation...

The New Art of Structural Engineering
Exerpt from The Tower and the Bridge: The New Art of Structural Engineering describes the career and the accomplishments of Thomas Telford,...

Finite-Strain Axial Analysis of Piles in Clay
In the late 1970's, a series of research projects developed simple effective-stress methods to predict the axial capacity of piles in normally-consolidated clay. The method...
