Purging the Plastics
A full-scale floating system designed to clean up the Great Pacific Garbage Patch for a fraction of the cost and time of traditional methods has been deployed....
Grid Pavement
Open grid pavements consist of concrete or plastic units with large surface openings filled with a permeable joint material, typically small aggregate (ASTM No. 8 or No. 89), sand, or...
Findings From a Joint Industry Study on Foundation Fixity of Jackup Units
During the design storm conditions the soil supporting jack-up unit footings may be close to, or at plastic failure. Accordingly, the use of elastic solutions to the problems of foundation...
On the Inelastic Design of Steel I Girder Bridges
This paper documents the development of a relatively easy to use set of effective plastic moment expressions and compares the performance of these equations with a series of experimental...
Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...
Fiber-Reinforced Polymer Composites for Construction�State-of-the-Art Review
A concise state-of-the-art survey of fiber-reinforced polymer (also known as fiber-reinforced plastic) composites for construction applications in civil engineering is presented. The paper...
Use of New Liner In Water Distribution System
For years there has been interest in rehabilitation of water distribution systems to provide quality drinking water and to reduce breaks in the water system service. Much work has been...
Liner Lessons
The County Sanitation Districts of Los Angeles County comprise 25 independent special districts that cover a service area of approximately 770 sq mi (1,990 km�). Since the early 1990s...
Glass Rebar's Growing Pain
Although engineers have used glass fiber reinforced polymer (GFRP) reinforcing bar in applications as diverse as winery roofs and bridge decks, a lack of standards and understanding by...
Not Your Father's Strain Gauge
A new type of strain gauge incorporates smart memory methods to assess changes in structures. Inexpensive, easy to install and durable, these gauges are passive peak strain sensors, which...
Evaluation Findings of the All Sign Products, Inc. Polycarbonate Stop Sign
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the HITEC evaluation of a plastic stop...
Plumbing the Quality of a Sewer System
Consultants in Phoenix were recently charged with assessing the city's sewer system, many feet of which were laid without plastic lining to protect them. Developing a capital...
Reinforced Glued Laminated Timber
In record time, reinforced glued laminated timber (glulam) has moved from an experimental product to wide-spread commercial acceptance. Several case studies illustrate applications and...
State of the Art
The structural engineering of San Francisco's new Museum of Modern Art offered many challenges to the engineer. The complexity of the building is both visually exciting and...
FRP Box-Beams Under Long-Time Static and Fatigue Loading
This paper discusses experimental and analytical aspects of the long-time behavior of filament wound E-glass fiber reinforced epoxy-box-beams. Theoretical and experimental data are compared...
Local Buckling of Pultruded FRP Beams: Theory and Experiment
A continuing experimental and theoretical investigation of the local compression flange buckling of commercially produced pultruded fiber-reinforced plastic (FRP) beams is briefly described...
Shear Design Guidelines for Polyester Concrete Using Recycled Plastic
Previous research on the shear behavior of steel-reinforced polymer concrete (PC) beams has been very limited and no efficient design procedures have been proposed. In all the previous...
Special Considerations in the Design of Connections for Recycled Wood/Plastic Composite Lumber
There is current work in the American Society for Testing and Materials (ASTM) to evaluate potential test methods for what they refer to as 'commingled' plastic lumber. This category covers...
Design Implications of Advanced Analysis in LRFD
This paper discusses two advanced analysis methods, and their use in LRFD format. The first approach is called the notional load plastic hinge method and the second is called the second-order...
Testing of Concrete Curtain Wall Panels Reinforced with FRP Grids
The objective of this paper is to evaluate the suitability of Fiber Reinforced Plastic (FRP) grids for use as a structural; reinforcement in concrete curtain wall panels. This paper describes...
