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...
Fast Tracking Military Waste
The installation restoration program, the military version of Superfund, helped fast track the cleanup contracts for four military hazwaste sites located at Hanscom Air Field, Bedford,...
Building a Better Landfill Liner
A soil liner project was sponsored by the EPA to provide information on the construction factors that affect the permeability of compacted soil liners. After construction of a field liner,...
The Saga of Senate Bill 2067
With the advent of the California Superfund program, liability related to toxic waste cleanup became a critical issue in California. The state had no authority to indemnify consultants...
Accelerating Electrons
At a wastewater treatment plant in Miami, five scientists have pointed a 1.5 million v `e-beam' at pathogens and hazardous chemicals. It's the only full-scale...
ATC-22: Development of a Handbook for ATC-14
The ATC-22 project is the development of a Handbook for the application of the methodology of ATC-14 for the seismic evaluation of existing buildings. The development of the Handbook itself...
Postearthquake Safety Evaluation of Buildings
Procedures for the safety evaluation of buildings in earthquake damaged areas have been developed. Two evaluation techniques, Rapid Screening and Detailed Inspection, are described. Rapid...
Seismic Evaluation of Buildings in the Eastern and Central United States
The Applied Technology Council (ATC) has developed and published a methodology, ATC-14, for evaluating specific buildings that is tailored for use by practicing structural engineers. ATC-14...
Retrofitting Existing Seismically Hazardous Buildings
This paper presents a brief overview of the types of problems encountered in retrofitting of existing seismically hazardous buildings. Included is a description of the various types of...
Historic Background of Seismic Construction in San Francisco
A seismic design and construction tradition has developed in California because of the unique experience with local earthquakes. After the 1906 earthquake and fire, building performance...
Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
Risk Analysis and Management of Natural and Man-Made Hazards
The third Engineering Foundation Conference on Risk-Based Decisionmaking titled Risk Analysis and Management of Natural and Man-Made Hazards was held in Santa Barbara, California on November...
Compaction Grouting as an Aid to Construction
The traditional use of compaction grouting has been to arrest settlement of existing structures, and occasionally to raise them back to their original grades. Recently, the process has...
A Geotechnical Analysis System with Applications for Drilled Shaft Foundations
The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several...
Risk Correction Factors for Bearing Capacity Analysis
In this paper bearing capacity correction factors are developed to account for the randomness in the load and soil properties. These are applied to the bearing capacity equation in the...
