Behavior of Concrete-Graphite/Epoxy Sections in Composite Bridge Girders
The focus of this work is on the behavior of composite bridge girders constructed from carbon-fiber-reinforced-plastic sections and concrete slabs. The study examines four-point bending...

Structural Performance of Hardwood-Metal Composite Beams
This research examines the deflection characteristics of layered timber/steel composite beams with hopes of applying such principles to large timber structures such as highway bridges....

Sprayed-Zinc Galvanic Anodes for the Cathodic Protection of Reinforcing Steel in Concrete
Corrosion of reinforcing steel bars (rebars), due to penetration of chloride ions from seawater affects the substructure of many bridges in marine service. In a new, low cost control method,...

Probabilistic Mechanics and Structural and Geotechnical Reliability
This proceedings consists of summary papers for the thirty-six technical sessions of the 6th ASCE Specialty Conference on Probabilistic Mechanics, and Structural and Geotechnical Reliability....

Portrait of a Manager
Although some are born leaders, most managers are actually created. In a perfect world, the young engineer would receive a bachelor of science degree in civil engineering, specializing,...

Evaluation of Seismic Vulnerability of Highway Bridges in the Eastern United States
For high risk seismic zones such as California, the state-of-the-art in earthquake resistant design for new highway bridges has been well advanced, especially since the damaging 1971 San...

Response of Model Pile Groups to Strong Shaking
The dynamic responses of small model pile groups to strong shaking obtained primarily from shake table tests are described and analyzed. As a basis for understanding pile group response,...

Seismic Pile-Group?Structure Interaction
A detailed multi-step procedure is outlined for a complete seismic soil-pile-foundation-structure interaction analysis, within the format of kinematic-inertial decomposition. Newly-developed...

Cone Models for a Pile Foundation
A single pile in a soil halfspace is modeled for dynamic excitation with disks and their corresponding double cones. This simple one-dimensional strength-of-materials approach provides...

An Alternative Analysis of Vibration Tests on Two Pile Group Foundations
Published quick-release horizontal vibration tests on two pile group foundations supporting large transformer banks are analyzed in this paper using the dynamic impedance approach embodied...

Forced Vibration Testing of an Expanded Base Concrete Pile
Forced vibration testing of a full-scale cast-in-situ expanded base concrete pile supporting a structural mass was conducted as part of a test pile program for a paper mill expansion at...

First and Second Order Dynamic Subgrade Models for Soil-Pile Interaction Analysis
The three-dimensional continuum solutions are used to examine the physical insight of a first order dynamic subgrade model, originally applied by Novak for dynamic pile response analysis....

Effects of Liquefaction on Lateral Pile Responses
The potential significance of the impact of liquefaction on the dynamic response of pile foundations has been studied through a numerical study. Results of this study demonstrated that...

Dynamic Parameters Analysis of Piles
This paper presents an analysis for the dynamic parameters of a single pile. The analysis allows consideration of pile-soil interaction, soil natural layered behavior and floating pile...

Soil-Pile-Superstructure System in Liquefaction
To obtain the dynamic behavior of the soil-pile-superstructure system in a liquefied sand layer, shaking table tests by using large scale shear bin (4m in length, 2m in width and 2m in...

Overlays on Deck
By the summer of 1993, a standard specification may be on the books for polymer concrete bridge-deck overlays�a high-tech rehab technique requiring a combination of plastic binder�such...

Minipile Milestone in Memphis
The maintenance/administration facility for Memphis, Tennessee's 300-bus fleet began displaying structural problems before it even opened for service in 1979. The 23 acre...

Engineering Pre-engineered Buildings
Pre-engineered buildings have become more sophisticated. There are several manuals and guides on how to engineer the so-called pre-engineered structures, but none are complete. There are...

Out with the Old
When the Sunshine Skyway Bridge over Tampa Bay, Fla., was partially destroyed in an accident twelve years ago, officials at the Florida Department of Transportation decided to replace...

Wave-Current Interaction with a Large Structure
The effects of a current on the diffraction of regular waves around a three-dimensional body are examined by a time-domain method. The Froude number is assumed to be small so that the...
