Information Availability
There seems to be a great deal of concern about lack of availability of information concerning the results of failure investigations. In most court cases there is virtually no technical...
Failure Information Needs in Civil Engineering
If we are to learn from failures of engineered facilities, failure information must be in a useful form, and it must reach those who can effect improved practice. This paper discusses,...
Learning from Failures
Modern technology and innovation have created a gap between what the design drawings predict with respect to safety and serviceability of a structure and the real safety and serviceability...
Learning from Failures: Procedural Changes in the Design and Construction Process to Reduce Failures
This paper first defines failures and their number and scope in the design and construction fields. It then presents the writer's opinion as to the cause of the failures and...
Failure Investigations in Undergraduate Education
Author stresses the need for failure investigations in undergraduate education especially in Civil Engineering. The civil engineer often creates only one major project of a kind, and is...
Small Water Users�Planning Crisis
Planning to rehabilitate small water systems�both irrigation and municipal water supply�often is ignored. In contrast, planning for new construction and for operations/maintenance work...
Nine Years' Service with Deep Polymer Impregnation
A test installation of deep polymer impregnation was applied to a heavily traveled bridge deck in Bethlehem, Pennsylvania, in 1975. The deep polymer impregnation process involved drying...
Analysis of Cracking of I79 Bridge at Neville Island
A large crack was discovered to form in a girder of the I-79 Glenfield Bridge over the back channel of the Ohio River near Pittsburgh on January 28, 1977. A section of the girder containing...
Investigation of Catastrophic Failure of a Premium-Alloy Railroad Rail
In November 1983 an Amtrak train derailed at a speed of 72 mph (115 kph) at Woodlawn, Texas (in the vicinity of Marshall, Texas), resulting in four fatalities and twenty-four serious injuries....
Time-Dependent Damage and Creep of Brittle Rock
In this paper, some results of a combined analytical-experimental study of the relationship between subcritical microcrack growth due to stress corrosion and the time-dependent deformation...
Liquefaction Flow Failure of Silty Sand by Torsional Cyclic Tests
The use of undrained strain-controlled cyclic torsional loading of anisotropically consolidated triaxial specimens (CyT-CAU tests), is proposed for evaluating liquefaction flow failure...
Clearing the Decks
Cathodic protection, an electrical-chemical process that prevents corrosion of steel rebars on bridge decks, is rapidly gaining acceptance by highway engineers and state highway departments....
New Cables for Old
In an eingineering first, the main suspension cables will be replaced on New York City's Williamsburg Bridge without closing it to traffic at any time. According to the design...
Structural Vibrations Associated with Large Incubation Tanks
It is the purpose of this paper to describe the format of an investigation wherein the train of evidence led from an assumption of a strictly mechanical cause to an actual cause that was...
Advances in High Strength Concrete,
The technology for producing field placeable concrete with a 28 day compressive strength of 10,000 psi has been available for many years. With the recent use of microsilica as an additive...
Aseismic Capability Prediction from Failure Data
Forensic engineering evaluations of failures have produced a wealth of technical data. In this paper, evaluation of representative failure data from one practitioner provided relevant...
Applications of Microcomputers for Bridge Design
This paper examines the role of microcomputers in the design divisions of state departments of transportation, specifically in bridge design applications. Consideration is given primarily...
New Analysis Techniques for Structural Masonry
These seven papers on analysis of structural masonry that constitute this Proceedings were presented at a technical session at the ASCE Structural Engineering Congress held at Hyatt Regency...
Reducing Failures of Engineered Facilities
One of the most serious problems of modern professional practice is the collapse or malfunction of an engineered facility. The tragic consequences of this problem are all too familiar...
Fracture Problems in the Transportation Industry
Six cases of damage tolerance assessment are presented, involving structures or vehicles in the U.S. transportation industry. Damage tolerance means arranging design, maintenance, and...
