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....
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....
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...
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...
Estimate of Economic Impacts of Climate Change upon US Water Resources Using Partial Equilibrium Modeling
(No paper) The use of the model is to determine the allocation of water between suppliers and consumers under present and future climates such that net economic benefits subject to regulatory...
Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...
Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...
Optimum Storage Reallocation and Gate Operation in Multipurpose Reservoirs
This research is intended to integrate long term operation rules and real time operation policy for conservation and flood control in a reservoir, the familiar yield model has been modified...
Singapore Showcase
A new bridge in Singapore has a unique pylon design and no piers. The deck hangs from the pylon supported by three back stays. The 100 m overpass bridge was designed for the Singapore...
Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...
Averaging Time and Maximum Speeds in Hurricanes
This paper discuses wind speed data obtained during Hurricane Andrew around Miami International Airport, at six anemometer locations which make up the wind shear warning network. Data...
Horizontally Curved Steel Bridge Research-Update 2
Theory and data necessary for the development and calibration of an LRFD based curved steel bridge specification do not presently exist. To address these needs, the Federal Highway Administration...
The Application of Streamflow Duration Curves in Water Resources Engineering
Streamflow duration curves are a useful graphical and analytical tool for illustrating the relationship between the frequency and magnitude of daily streamflow. They are commonly used...
Intelligent Decision Support System for Stage Discharge Analysis
A Decision Support System (DSS) for fitting stage-discharge (S-D) relations is being developed by the University of Manitoba, Facility for Intelligent Decision Support, for Environment...
