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...
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...
Behavior and Strength of Telescopic Steel Shores
To study the load distribution between concrete floors and shores during construction, the non-linear axial load-shortening behavior of a single post shore must be modeled properly. In...
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...
Seattle Swing
The swing bridge has long been out of favor in the U.S. because of the navigational hazard presented by mid-channel pivot piers. A consortium of engineers is updating the design to a state-of-the-art...
Replacing Bridge Decks
U.S. bridges last an average of 68 years, their decks 35 years. But few bridges have been built with provisions for future deck repair, the only criterion being lowest first cost. During...
Building Blocks for the Future
In the near term, advanced, conventional materials�namely higher-strength steel and concrete�will dominate infrastructure rehab. New steels of higher strengths and toughness are increasingly...
Designing in Circles
Round buildings are a popular�but sometimes expensively perceived�design choice. With careful engineering and planning, they can offer a creative, cost-competitive option. They add another...
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...
Aussie Steel
The 50-story Chifley Square Building being built in Sydney will be the tallest Australian steel building. Scheduled for completion in June 1992 at a cost of $310 million, it will house...
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...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
Rebuilding Philadelphia's El
In reconstructing an urban transit system, the challenge in Philadelphia was to do it without disrupting peak hour commuter traffic or disturbing activities on the street and sidewalks...
Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...
