Notable Unbuilt Bridges
In the examples of unbuilt bridges discussed, many different ideas and concepts have been proposed. Most appear to be basically sound in nature, although rather innovative and daring....
An Integrated Knowledge System of Seismic Vulnerability and Risk for Engineered Facilities
This paper describes an integrated knowledge system for the assessment of the seismic vulnerability and risk of engineered facilities. The system integrates knowledge from many fields...
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Evaluation and Remediation of Construction Defects in Tilt Wall Panels
Both the surface appearance and structural safety were of concern to the Owner of a five year old warehouse structure that was experiencing delamination of tilt-up wall panels. Delamination...
Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...
Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...
Issues in the Validation of Probabilistic Methods
Probabilistic models are being used increasingly in safety assessments and regulatory decision-making. There is a need to relate the risks computed using these models to service data in...
Applications of Probability for Structural Analysis in the Nuclear Industry
Probabilistic techniques are being used as part of structural analysis in the nuclear industry to investigate various safety-related issues. Historically nuclear power plants have been...

The Civil Engineering Foundation ? A New Beginning
The United States' construction industry is ailing, experiencing a decline that rivals that of the auto and other US manufacturing industries. How the decline is to be halted...
Toward an LRFD-Based AASHTO Bridge Specification
During the 1987 AASHTO Bridge Committee Meeting, recommendations from NCHRP Project 20-7/31 regarding the development of a probability-based LRFD bridge specification were accepted. NCHRP...
Evaluation of Bridge Safety and Remaining Life
In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example...
LRFD: Progress for Engineers and the Wood Industry
The LRFD for Wood project represents a milestone for the industry. The significance of the project goes far beyond merely switching formats in design equations. The project signifies both...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
Codified Reliability for Structures During Construction
It is generally acknowledged that the most critical stage of a structure's lifetime is that of construction, leading to failures or locking in forces and deformations that...
Remote Automatic Data Acquisition Systems
Personal computers have been used on two projects to monitor peformance of structures in an automatically triggered mode. In both cases a local PC is used to continually monitor a triggering...
On-Site Incineration
A variety of equipment is now available for incinerating hazardous wastes in situ. Thermal treatment, compared to land disposal, offers limited liability and immediate destruction. It...
