Forging Ahead
More than a dozen bridges in the United States have been built using HPS 70W grade steel, which has a yield strength of 485 MPa (70 ksi) but superior toughness compared to conventional...
Making the Connection
This article details the results of a pilot research project on the use of polymer composites and high-strength adhesives for the structural repair of damaged steel frame connections....
High Rise Express (Available in Structural Engineering Special Issue only)
A new column system developed by the Canam Manac Group in Montreal offers the expediency of steel construction with the economy of concrete. The system is made entirely of lightweight...
Covered Bridge Connection (Available in Structural Engineering Special Issue only)
A 145-year-old timber bridge in Downsville, New York, now rests on the longest glue-laminated wood beams ever produced in the United States. Six 53 m (174 ft) long chords were threaded...

Order Amid Uncertainty (Available in Geoenvironmental special issue only)
Bayesian statistical methods allow engineers to deduce probabilities from incomplete information. If there is a theoretical or empirical reason why a particular probability distribution...
Up against the Wall (available in Geoenvironmental special issue only)
A tight site in Portland, Oregon, bounded by existing roads and a light rail line and bordered by underground utilities, required project engineers to develop a new type of shoring wall...
Metal Building Systems: A New Look
The use of metal building systems in low-rise, non-residential construction under 150,000 square feet has grown from less than 50 percent in 1986 to almost 70 percent today. Such systems...
Del Webb's Innovative Approach to Master-Planned Community Development
(No paper) The Del Webb Corporation is currently building a master planned development on the northern edge of Maricopa County. The development plan includes a water campus housing a water...
Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
Urban Runoff Toxicity
Toxicity is controlled by the magnitude/concentration of the contaminant produced in an exposure, the duration of the exposure, and the frequency with which exposures are repeated. When...
Impacts of CSO Swirl Concentrator on Dissolved Oxygen Concentrations in the Anacostia River
Purpose: To assess impacts of the CSO control, two continuous monitoring stations were located upstream and downstream from the CSO outfall. The monitors recorded dissolved oxygen (DO),...
Selection of an Optimal Ecosystem Restoration Plan: Decision-Making Criteria in the Planning Process
(No paper) This paper explores various decision criteria for restoration projects and how they may be modeled with existing decision models. Cost-effectiveness, incremental cost analyses,...
Saving San Antonio
During an October 1998 flood, excess flow from the San Antonio River was funneled into a 3.1 mi (5 km) long, 24 ft (7.3 m) wide concrete-lined tunnel beneath the city that emptied into...
