Investigation of Coastal Conditions at Oregon Inlet, NC for the Replacement of the Herbert C. Bonner Bridge
The Bonner Bridge across Oregon Inlet was constructed in 1962 and is approaching the end of its service life. Planning for a future crossing must consider natural inlet migration expected...
Naval Pier Foundation Design and Construction, Pearl Harbor, Hawaii
The paper presents a case study of foundation design and construction for a pier in Pearl Harbor. The study covers a review of site investigations, laboratory testing, pile selection and...
Subaqueous Disposal Area Development and Mitigation
Development of subaqueous dikes on soft soils extensively utilized geosynthetics. The design adopted a wide-bermed embankment with high-strength geotextile for tensile reinforcement and...
Seismically Safe, Spectator-Friendly
As 50,000 frightened spectators at Candlestick Park can attest, the Loma Prieta earthquake in 1989 provided chilling evidence of the importance of seismic design in public structures....
Engineering a Monument, Evoking a Nightmare
Rather than simply standing as a backdrop for exhibits, the $53.2 million U.S. Holocaust Memorial Museum is intended to be part of the fabric of the exhibition itself. Now under construction...
Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...
Nondestructive and Destructive Testing of a Three Span Skewed R. C. Slab Bridge
A three span, skewed, reinforced concrete slab bridge was field tested to destruction by the authors. Before the actual destructive test, nondestructive tests were performed to determine...
Safeguarding Steel
U.S. bridges are caught in the money squeeze. Painting has become a luxury few public agencies can afford and complying with EPA regulations has escalated costs even more. The paint/coatings...
Piles Over Problems Sites
It's increasingly difficult to find suitable space for construction in urban areas. Pile foundations can fill the void by making questionable and heavily regulated sites,...
Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...
On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...
Bayesian Reliability Updating of Existing Steel Girder Bridges
Bayesian statistics is used to update the reliability of existing composite steel girder bridges. A 60 ft. long simply supported superstructure is considered. The reliability for the ultimate...
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Refined Analysis of Load Distribution Factors for Bridges
This paper presents a new approach for calculating the distribution factors for slab-on-girder bridges. This method considers the coupling of longitudinal and transverse effects. The governing...
Frictional Aspect of Rocking-Sliding of a Rigid Block with Surface Impact
During the very short time of impact between a rigid rectangular block and a rigid foundation, the interface pressure distribution varies with time in a complicated manner. Due to this...
Dynamic Effect of Sediment on Dam Hydrodynamics
The dynamic behavior of reservoir sediment during earthquakes is important to an analysis of dam safety when the depth of the water is seriously reduced by the sediment. While the dynamic...
Evaluating Polymer Concrete Bridge Expansion Joints Using Acoustic Emission
This study is to simulate the acoustic emission (A/E) of polymer concrete bridge expansion joints subjected to controlled representative loads by a rotating test apparatus on a circular...
Stress Wave Interaction in Finite Beam on Elastic Foundation
The short-time behavior of a finite Timeshenko beam on a Winkler foundation subjected to step and impulse loadings is presented. The transient behavior was analyzed by using the method...
