Hybrid (FRP+Steel) Reinforcement for Concrete Structures
The most popular method to prevent corrosion of steel rebars and prestressing tendons is epoxy coating. This paper presents an alternative approach consisting in the combination of a fiber-reinforced-plastic...

Investigation of the Behavior of Reinforced Plastic Columns with Concrete Core
This paper describes an experimental investigation into the behavior of reinforced plastic columns with tubular (hollow) sections. The columns were pultruded and had a cross-section which...

Behavior of Externally Confined Concrete Columns
This paper investigates the feasibility of strengthening of seismically deficient concrete columns with high-strength fiber composite straps. The concrete columns will be externally confined...

Fiber/Epoxy Composites Strengthen Bridge Columns
The California Department of Transportation is using high strength fiber/epoxy composites to strengthen existing reinforced concrete bridge columns. These advanced composite materials...

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...

Nonprestressed and Prestressed FRP Sheets as External Reinforcement of Wood Members
The paper presents a summary of an analytical and experimental investigation of a new form of wood construction involving external bonding of thin fiber reinforced plastic (FRP) sheets...

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...
