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...
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...
AE Instrumentation and Deconvolution Techniques
This paper describes the difficulties and solutions achieved in applying advanced Acoustic Emission (AE) signal analysis techniques to fracture mechanics. The test specimen is a double...
Evaluation of High Strength Concrete by the Break-Off Method
The reliability of the Break-Off method to test inplace high-strength concrete is investigated. A total of 188 Break-Off tests and 30 standard cylinder tests are carried out for this project....
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...
Application of Waterjet Cutting for Pothole Repair
A study was conducted to determine the feasibility of utilizing high pressure waterjet cutting technology as an infrastructure maintenance tool. The influence of waterjet cutting parameters,...
Lime-Fly Ash-Aggregate Base and Subbase Courses
This paper describes the use of lime-fly ash-aggregate (LFA) base and subbase courses for highway pavements. This type pavement course is considered as an alternate to cement treated bases...
Inelastic Stability of Thin Walled Metal Tubes Under Cyclic Loading Conditions
This paper is concerned with an experimental investigation on the inelastic stability behavior of thin-walled tubular specimens of steel, aluminum and stainless steel, under cyclic loading...
Localization Instabilities Due to Damage and Fracture Propagation: Application to Tensile Specimens
In recent research it has become clear that localization of damage due to strain softening as well as propagation of interactive cracks can result in bifurcations of the loading path characterized...
Compressive Strengths of Lean Concretes Containing Fly Ash
The compressive strength development of lean concretes containing fly ash was evaluated. Concretes were prepared at total cementitious materials contents of 423, 517, and 564 lb/yd3...
Anomalous Structural Size Effect in Cohesive Materials Like Concrete
This contribution analyses on theoretical grounds the size effect trends in special cases where - unlike most experimental situations in fracture research - the specimen is not precracked...
Design and Performance of Earth Retaining Structures
The proceedings of the 1990 Specialty Conference on Design and Performance of Earth Retaining Structures was held in Ithaca, New York from June 18-21, 1990. It presents a total of 50 papers...
The Dredging Dilemma
Disposal of dredge materials is becoming a national environmental problem. Disposal sites on land are becoming extremely scarce and environmental objections growing. There are also objections...
Siphon Quenches Drought
An age-old engineering concept�the siphon�enjoys new success in alleviating a severe water shortage at the Ketchikan Pulp Company's Ward Cove Pulp Mill. With major layoffs...
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...
Commentary on Building Code Requirements for Masonry Structures (ACI 530-88/ ASCE 5-88) and Commentary on Specifications for Masonry Structures (ACI 530.1-88/ ASCE 6-88)
U.S. Landmarks: Handle With Care
Landmarks are treated with kid gloves during restoration, but striking a balance between costs and aesthetics is difficult. In addition to structural integrity, original construction methods...
