Geotechnical Innovations: Why Seldom Used in Highways?
Ground improvement methods introduced within the past decade to American geotechnical engineers offer cost savings, ease of construction and reduced construction time. Amont these innovations...
Surveying's New Promise: Centimeters from Space
One centimeter accuracy at far less cost than surveying by traditional methods is promised by the Global Positioning System (GPS). Signals from NAVSTAR satellites are received by two or...
Can Digital Terrain Data Cut Route Selection Time?
The use of photogrammetry in the collection of digital terrain and the use of a computer to process data is not being used to its fullest. Use of these two tools together increases access...
Experiences with Micros in Project Controls
The experience of one and one-half years of microcomputer use in project controls is related, with the intent of helping the system buyer anticipate useful applications, and suggesting...
Trends in Small Computer Utilization
In an effort to determine the extent to which micro and minicomputers have been successfully implemented by construction contractors, the authors compiled a comprehensive questionnaire...
Look Again at Quality Circles
Companies in many countries have tried or are trying quality control circles as a major part of their productivity improvement programs. A quality control circle uses the experience and...
Computing in Civil Engineering
A broad spectrum of computer applications in civil engineering is covered in 73 papers presented at the Third Conference on Computing in Civil Engineering. Emphasis is on microcompters...
Frost Action and Its Control
This state-of-the-art review addresses, in four separate papers, frost heave processes and their control. A review of the fundamental principles of soil freezing and thawing is presented...
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...
Enhancing Quality of Construction on Nuclear Facilities
From the author's viewpoint and the viewpoint of others, the quality of construction on both nuclear projects and many other non-nuclear projects has decreased. The trend...
Integrated Testing and Analysis
This paper represents a new approach which greatly streamlines the entire process. In those cases where finite element modeling is used without test verification, the procedure consists...
Major Considerations in Scale Modeling of Reinforced Concrete Containment Structures
Reinforced concrete containment structures pose unique modeling problems, especially when leakage integrity is of interest. This paper presents a general discussion of modeling considerations...
Analytical Solution of Cable Tray Hanger 3D Structural Interaction under Seismic Loading
Structural design of cable tray hangers is controlled by the Nuclear Regulatory Commission's stringent requirements of seismic analysis. A finite element space frame model...
Transient Fluid-Structure Interaction of a Cylindrical Tank with a Flexible Baseplate
Analytically predicted coupled natural frequencies, response functions, and transient responses are compared with measured values for a partially filled cylindrical tank subject to excitation...
Fluid Structure Interaction Analysis of a Concrete Suppression Chamber of Mark I Containment System
Recent studies have demonstrated that the interaction between a structure and fluid can have a significant influence on the response of the overall system when subjected to certain dynamic...
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...
Safety Investigations of Existing Spent Fuel Storage Structures for Increased Spent Fuel Storage Capacity
Delays in the solution of disposal problems continue to create the need for additional on-site spent fuel storage capacity at commercial nuclear power generating facilities. Rod consolidation...
ACI 349 Embedments: Code Provisions and Methods of Analysis
Steel embedments form the critical link between steel and concrete structures. Appendix B of ACT 349, Code Requirements for Nuclear Safety Related Concrete Structures, specifies the ultimate...
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...
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....
