1986: The Year of the Connection
It is proposed that 1986 be designated the Year of the Connection and that the American Society of Civil Engineers take a leading role in overcoming problems now associated with structural...
Civil Engineering Productivity�Can It Be Boosted?
In the past 20 years, construction labor productivity has declined while private business productivity has risen. And construction's percent of U.S. GNP has dropped nearly...
Application of Methods of Probabilistic Characterization of Soil Properties
The use of probabilistic methods to describe soil properties has many applications. One such application that has been developed is in the area of probabilistic slope stability analysis....
Building Failures�Construction Related Problems and Solutions
A leadership group of representatives from the fields of structural design, construction, building inspection, the law and insurance agreed that if five changes are made in the way building...
The Case of the Bungled Bridge Rehab
Foundation failures and rehabilitations concern the owner, the engineer and the contractor. These parties face liability to one another as well as to third parties. There are contractual...
Building Failures: Design Problems and Solutions
A Building Failures conference of the Engineering Foundation dissected the problems leading to failures and recommended ways to reduce failures. This article discusses value engineering,...
Engineering Liabilities for Design of a Bridge That Failed During the San Fernando Earthquake
On February 9, 1971, the San Fernando Valley in Southern California experienced a major earthquake. Among the victims were two men who were killed when a bridge connector ramp of a newly...
Dome
Roofed with the worlds largest diameter wood dome at 530 ft., the Tacoma Dome, a multi-purpose sports and convention center has helped revitalize a blighted part of that Washington state...
Reservoir
To preserve a vital part of the St. Louis, Mo. water supply , Stacy Park Reservoir was renovated with a new concrete roof over half its area and new beams in the other half. The new roof...
Nonlinear Analysis of Reactor Vessel & Core Supports Subjected to Accidental Impact Loads
Nonlinear dynamic analyses of the reactor vessel, its support systems, the core and the core supports were performed to evaluate the consequences of such drops. Damage was defined in terms...
A Study of the Correlation of the Components of Instructure Motions During Earthquakes
Thirty-two buildings are selected that have all three components of motion recorded in the basement, midheight and top of the structure. The correlation coefficients of these motions,...
Modeling Techniques for Seismic Analysis of Supported Systems
An automated seismic qualification process is presented which integrates the modeling and evaluation aspects of supported system design. Emphasis is placed on baseplate and joint design....
Development of Concrete Nuclear Containment (ACI 359) Code Requirements as they Relate to Probability Based Load
The historical development of the load combinations used in concrete containment is presented in the paper. These load combinations are examined and identified in the light of the reasonable,...
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...
Containment Capability
Section 2. 0 of this report contains a description of analysis methods for the containment structure. Testing on containment models and sections of containments is described. Section 3....
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...
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...
Hydraulic Uncertainty in Risk Analysis
Considerable effort has been expended in defining and evaluating hydrologic uncertainties; however, the analysis and evaluation of hydraulic uncertainties has received little attention....
Upper Hudson River Valley Dam Break Model
In order to determine areas of inundation due to the failure of Conklingville Dam, a dam break analysis was performed, and the resulting outflow hydrograph was routed through the downstream...
