Corrosion Life-Time Assessment of Carbon Steel and Stainless Alloys for Geological Disposal Facility
The disposal facility for radioactive wastes, requires long-term integrity. Metal is considering to use as the engineered barrier which constructs the outer walls in such a facility, in...
Localized Corrosion Prediction for Nuclear Waste Disposal Container Materials
When the bentonite is used in the geological disposal of high-level wastes as a buffer material to stand between containers and host rocks, thereby turning the pH of the groundwater slightly...
Columbia River Basin Fish and Wildlife Program Strategy for Salmon
Three species of Snake River salmon have been listed as threatened or endangered under the federal Endangered Species Act. In response, the Northwest Power Planning Council worked with...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
Object-Oriented Finite Element Modeling
The present paper studies the suitability of object-oriented modeling strategies for problems of structural mechanics. After a general discussion of the topic, special emphasis is put...
Optimum Design Software Package for Shortening Civil Engineering Construction Period
The optimum software package for engineering network has adopted a coverage technology to facilitate an analysis of large-sized projects. This package has the following functions: (1)...
An Application of Neural Networks to Hysteretic Modeling of Steel Structures
This paper describes an application of the neural networks to realistic hysteretic modeling. The neural networks learn from sample data (training cases) and make predictions for new cases....
Computer Assisted Conceptual Structural Design of Steel Buildings
The design quality of a building is mostly determined during the conceptual design stage. Computers, however, have not been used effectively to handle the conceptual design of building...
NEUROFLOOR: A Flooring System Selection Neural Network
A back-propagation neural network (BPNN) has been trained to help building designers and engineers in designing or analyzing steel bar joist flooring systems. The NEUROFLOOR BPNN allows...
Computer Aided Experiments for Truss Structures
It is quite difficult to investigate structural mechanical properties by full scaled structure experiments. Consequently, an experiment using a reduced scale model is generally performed....
Secondary Member Contribution to the Behavior of Damaged Multigirder Highway Bridges
This paper examines the effects of secondary members (cross bracing and diaphragms) on the prediction of the response of damaged simple span steel multigirder bridges. Extensive analytical...
After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
Assessment of Guideway Systems for Maglev Applications
Recognizing the potential benefits of MAGLEV high speed mass transportation systems, three innovative guideway systems have been evaluated herein from the viewpoint of: (1) loads and performance...
Making the Leap
Over the past decade, computers have become as much a part of the engineering field as concrete and steel. But bringing a firm into the information age can be complicated and expensive....
A Wave-Energy Dissipation Structure for Shore Protection and Beach Generation, Recovery, and Stabilization
WAVEBLOCK a steel reinforced concrete modularized structure designed to dissipate the energy of saline and freshwater waves is described. The modularized structure, which weighs upwards...
Application of Composite Members to Marine Structures in Japan
Composite structures combined steel plates and reinforced concrete with shear connectors have been applied to port and harbor facilities in Japan since the early 1980s.Composite structures...
Steel Penstocks
Lead is a Four-Letter Word
New regulations and strict enforcement make it difficult and expensive to remove lead-laden coatings from steel structures. Lead-based primers and paints are not considered hazardous as...
Local Scour at Bridge Piers in Alberta?Case History
A two span steel truss bridge with a rectangular concrete central pier was built over the Oldman River near Brocket in south-west Alberta in 1954. Initially the bridge was built square...
