Laboratory Fatigue Investigation of a GRP Bridge
A fatigue study of a 4.9 m glass-reinforced plastic bridge indicated a resistance to 1.6 million cycles of load without extensive damage to joints or elements. Viscoelastic creep occurred...
Concepts for Hybrid FRP Bridge Deck Systems
This paper presents selected structural concepts for modular bridge deck systems taking into account the limitations imposed by fabrication processes for polymer matrix composites. An...
Development of High Strength Composite Cables
Fiber reinforced composite materials offer significant advantages over conventional materials for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages...
Properties of Flyash Cellular Concrete
A research program was conducted with the aim of studying the physical and flexural properties of cellular concrete containing flyash. Two different types of fibers were also added to...
Bond Stress-Slip Relationships of FRP Rebars in Concrete
A newly developed type of reinforcement bar for concrete, Fiberglass Reinforced Plastic (FRP) rebar, can be used advantageously in concrete exposed to marine or corrosive environments....
Fatigue Behavior of Bond-Anchored Unidirectional Glass-FRP's
The contribution reports on the fatigue behavior of fiberglass reinforced plastic (FRP) bars, consisting of endless E-glass fibers embedded in a polyester (PE) matrix and anchored in a...
Flexural Strength of Externally Reinforced Concrete Beams
Results from tests of one rectangular and one T-beam are reported. The beams were strengthened by epoxy-bonding a 1/4 in. (6 mm) thick Glass Fiber Reinforced Plastic plate along the tension...
Feasibility of Class C FRP Load Transfer Devices for Highway Jointed Concrete Pavements
The objective of this paper is to analyze the feasibility of using corrosion free fiberglass reinforced plastic (FRP) devices in lieu of steel tie bars in the longitudinal joints of highway...
Uni- and Bi-Axial Compressive Fatigue of Fiber Concrete
Fatigue behavior of fiber reinforced concrete is studied under uniaxial and biaxial loadings. The S-N curves and the cyclic deformations of fiber concrete are compared to those of plain...
Bond Strength of Fiber Reinforced Plastic Bars in Concrete
In this study, 27 beam specimens were tested to determine the bond strength of fiber reinforced plastic bars (FRP) in tension. The specimens were reinforced with #4, #6, or #8 FRP bars....
Measurement of Impact Fracture Toughness of FRC
Instrumented impact tests have been in use since the early eighties for studying the fracture characteristics of cement-based composites at high rates of loading. While significant progress...
Flexural Behavior of Synthetic Fiber Reinforced Rapid Set Materials
This paper presents the results of a laboratory investigation on the contribution of synthetic fibers to the flexural behavior for three typical rapid set materials. Three types of synthetic...
Detection of Small Voids by Impact-Echo and Signal Processing
The Impact-Echo method was used to detect slab thickness, presence of small voids and reinforcement locations in a concrete slab. Studying the frequency response of the slab, it is possible...
Displacement Measurement by Laser Interferometry and Image Analysis
Laser holographic interferometry was used for the evaluation of displacement fields on concrete and fiber reinforced concrete specimens. Transmission holography was used to analyze mortar...
Significance of Yield Surface Corner-Like Effects in Inelastic Stability Solutions
This paper presents the author's experiences with finite element prediction of the inelastic stability of steel plate structures. The implications of linear versus nonlinear...
Instrumenting for Eternity (Almost)
Prendergast describes the safety features and instrumentation for a low level radioactive waste disposal facility planned for Illinois. Federal law requires that each state or group of...
Bibliography of Steel Columns
This book, which was prepared by the Committee on Compression Members of the Structural Division of the American Society of Civil Engineers, attempts to provide a complete bibliography...
Grouting Slip Liners: The New Inside Story
There are approximately 800,000 miles of water and sewer pipelines in the U.S. that need remedial work. About 2% need work each year, usually due to normal or accidental corrosion. Normal...
Replacing an Urban Foundation
Baltimore's new subway extension will pass close to a 6-story reinforced concrete building near the Inner Harbor. Its timber piling foundation was threatened by the dewatering...
Retaining Forest Roads
The U.S. Department of Agriculture, Forest Service, manages a vast system of roads which provide access to America's national forests. More than 250,000 miles of roads exist...
