Upriver Dam Hydroelectric Project Rehabilitation After Failure, Part A: Failure Investigation and Lessons to be Learned
A lightning strike caused electrical failure at Spokane's two Upriver power plants, resulting in the river overtopping Project embankments, and causing nearly 11. 5 million...
Upriver Dam Hydroelectric Project Rehabilitation After Failure, Part B: Rehabilitation and Enhancement of Project Civil and Mechanical Facilities
A feasibility investigation of rehabilitation alternatives was conducted which identified several alternatives for repairing the damage and placing both powerhouses back on-line. These...

Building Bridges Faster
Guidelines are presented that tell how to write a contract that will lead to radical reductions in the time to build or rebuild a bridge. The article covers how to write an incentive/disincentive...
Treatment of Karst Along Tennessee Highways
The construction and maintenance of highways in karst areas of East Tennessee has resulted in the occurrence and treatment of induced sinkholes along the ditchlines of numerous highways....
Finite Element Analyses of the St. Alban Test Embankments
Finite element analyses were performed of three embankments on sensitive clay that were constructed to failure at St. Alban, Quebec. One of the embankments was reinforced with flat-lying...
Laboratory Study of Geogrid Reinforced Soil Walls
The paper describes the construction and testing of three (3) large-scale geogrid reinforced soil retaining wall models. The models were 3 m high and were built in the RMC Retaining Wall...
On the Post-Flutter State of Cable-Stayed Bridges
This paper deals with the post-flutter vibrations of cable-stayed bridges. An approximate theory and an approximate analytical solution method have been established. A numerical example,...
Burlington Cable-Stayed Bridge
The Burlington cable-stayed bridge will carry US34 over the Mississippi River from Burlington, Iowa to Gulfport, Illinois. There will be two 12-ft lanes in each direction plus an acceleration...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
New Parallel Wire Bundle for Cable-Stayed Bridges
A parallel wire bundle is described which is twisted with a long lay length. It is corrosion protected by an inner fill and outer coating of polyurethane. It presents a specially shaped,...
Probabilistic Prediction of Pile Group Capacity
A reliability analysis of a group of free standing piles in clay is carried out using Monte Carlo simulation. The pile material strength, soil capacity, and the load on the pile group...
Development of Bridge Design Code
Load and resistance parameters for bridges involve uncertainties due to natural randomness, imperfect models or human errors. Because of these uncertainties, absolute reliability is not...
Probabilistic Fatigue Crack Growth Analysis with Reliability Updating
A randomized fatigue crack growth model based on the Paris and Erdogan crack growth equation is used to estimate the reliability of fatigue sensitive details in steel bridges. This model...
Fracture Control for Arctic Vessels and Structures
Materials used for construction of Arctic structures and vessels are exposed to low ambient temperatures, high local ice loads and intermediate to high loading rates. All these factors...
Methods to Estimate Parametric Sensitivity in Structural Reliability Analysis
Many different approaches are used in structural system reliability to estimate the probability of failure. In this paper, methods to obtain the sensitivity to the distribution parameters...
On the Evaluation of System Reliability Through Automatic Generation of Failure Modes
This paper proposes a method for the evaluation of structural failure probability taking into account all the potential failure modes. At first, the failure paths to produce failure modes...
Reliability Based Analysis of Contact Problems
The S.B. Batdorf model is modified to include the reduction in shear due to the effect of compressive stresses on the crack face. This new formulation was used to obtain the probability...
Reliability of Geotechnical Systems Considering Geological Anomaly
Anomaly statistics at a given site are first assessed through Bayesian methodology on the basis of site exploration data. Several methods may be then used to incorporate the anomaly uncertainties...
A Probabilistic 3-D Short-Term Slope Stability Model
A probabilistic model to analyze the three-dimensional stability of earth slopes under short-term conditions is presented. An actual failure case is studied to show the implementation...
