Estimation of Consolidation Properties of Clay from Field Observations
Analyses to obtain theoretical time-settlement curves for embankments typically make use of soil properties measured in the laboratory on small disturbed samples subject to strain rates...
Effective Stress Theory of Soil Compaction
The shape of the moisture-density curve obtained from compaction tests has been explained in terms of capillarity and lubrication, viscous water, and physico-chemical interactions. None...
Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...
Members Subjected to Torsion Combined with Other Actions
The combination of torsion with bending and shear (T-M-V) in members with both transverse and longitudinal reinforcement is the most commonly encountered combination in practical cases....
Ahead of the Curve
Four curved steel girder bridges for Pittsburgh's light-rail project posed challenges ranging from multiple site constraints to special rail loads and welded rail interactions....
Using Tracer Response Curves to Quantify Hydraulic and Channel Complexity of Prairie Creek, Northwestern California: Implications for Over Wintering Habitat for Juvenile Coho Salmon
This study measured and compared aspects of channel structural complexity with hydraulic complexity at a range of flows including winter storm flows. Five 200-meter reaches containing...
Size Effect on Stress-Strain Curves of Concrete
Fragility Curves and Seismic Loss Estimation Methodologies Based on Insurance Data
Loss data for single family dwellings from the 1994 Northridge, California, earthquake were correlated with ground motion with the aim of determining ground motion-based fragility curves....
The Effect of Locked-In Curvature on PCC Pavement
Sharp Curves
In Madison, Mississippi, just north of Jackson on Interstate 55, a diamond interchange with State Route 463 has become a bottleneck for commuters and local motorists. But the typical solution—a...
Competitive Edge
A new design system called the simplified economical bridge design (SEBD) makes steel cost-competitive with concrete for short- and medium-span bridges for the first time. In fact, a comparative...
Re-Creating the Rainbow Bridge
A team of American and Chinese experts constructed a pier-free arch bridge in China based only on a 12th century...
Another Direction
Soil and groundwater contamination continues to be a problem throughout the United States, and on-site remedies are often time-consuming and costly. When such contamination lies underneath...
Tight Squeeze
The Newark, New Jersey Route 21 Viaduct Replacement is a massive, $250 million highway improvement program being undertaken by the New Jersey Department of Transportation. Michael Baker...
In Plain View
(Available only in Special Structural Issue) A structural engineer's work is typically hidden beneath layers of concrete and plaster, but the Pittsburgh Civic Center in the...
