Characteristics of the Flood Release-Induced Vibrations with Qianshui Thin-Arch Dam
In this article the prototype observations and design analyses are described regarding the flood release-induced vibrations of the Qianshui thin-arch dam and its foundation; and their...
Critical Flow Through Bridge Piers
A physical model study was performed at California State University, Long Beach to investigate the location of critical depth within bridge piers in supercritical lined channels. This...
Long-Term Strength Gain or High Strength Concrete as Monitored by Drilled Cores
An evaluation was made of the relationship between standard cylinders, four-inch by eight-inch cylinders, and drilled cores. The evaluation results showed that the strengths obtained from...
Field Installation of Strain Gaged Geotextiles
High-strength polyester geotextiles were used in two major Corps of Engineers projects: Wilmington Harbor, Del. and New Bedford, Mass. To verify design assumptions and as part of monitoring...
Seattle Swing
The swing bridge has long been out of favor in the U.S. because of the navigational hazard presented by mid-channel pivot piers. A consortium of engineers is updating the design to a state-of-the-art...
Leveling the Playing Field
As professional sports grow, so does the market for elaborate multi-use sports arenas. The new Target Center in Minneapolis features a unique movable floor, 68 luxury suites and a state-of-the-art...
Anchoring a Dam
To comply with Federal Energy Regulatory Commission requirements with regard to stability under a postulated Probable Maximum Flood, an extensive foundation investigation and stability...
New Piers for an Old Bridge
Placing new piers under an old superstructure has saved the architecture of the historic Ashley River Bridge in Charleston, S.C. In July 1987, an inspection indicated deterioration and...
Notable Unbuilt Bridges
In the examples of unbuilt bridges discussed, many different ideas and concepts have been proposed. Most appear to be basically sound in nature, although rather innovative and daring....
An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...
BABE: An Expert System for Structural Design of Bridge Abutments and Piers
A knowledge-based expert system named 'BABE' (Bridge and Building Evaluation) has been developed for the purpose of helping the user in planning, analysis and...
Current Research and Future Developments
A review of current research projects at the National Science Foundation on bridge engineering are reviewed and discussed with respect to immediate and future impacts. A look into the...
The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...
Effects of Vertical Motion on the Inelastic Behavior of Highway Bridges
The response of typical highway bridges to the vertical component of earthquake ground motion has a significant effect on their elastic behavior. When vertical motions are considered along...
Characteristics of a Structure-Foundation System
The dynamic characteristics of the structure-foundation system of a 1/4 -scale nuclear power plant containment model is studied using seismic records. The model structure is treated as...
Hydrodynamic Interaction Effects in Earthquake Response of Arch Dams
With the aid of earthquake response results it is demonstrated that the following hydrodynamic effects should be considered in the analysis of the earthquake response of concrete arch...
Big-Scaled Tilt Test on Uplifting Behavior of Oil Storage Tanks
The authors conducted a series of static tilt tests using a very big model with the full similitude in order to investigate the uplifting behavior of large-scaled tanks. The model was...
Seismic Vulnerability and Upgrading of Buildings Geotechnical-Geological Aspects
The effects of local soil conditions on the characteristics of earthquake motions (soil amplification) and on the dynamic response of structures for a given foundation type (soil structure...
Seismic Isolation of the USC University Hospital
This paper provides an overview of the various structural engineering tasks that are associated with the implementation of the design of a seismically isolated structure. The project is...
