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...
Finding the Right Bond
Professors and students from a Swiss university built a dual-span glass fiber reinforced polymer (FRP) bridge to gain a better understanding of how composite materials behave and how best...
Muscle Made of Carbon Fiber
Carbon fiber reinforced plastic (CFRP) extends service life and increases load-bearing capacity when applied to concrete structures. CFRP is less expensive than traditional strengthening...
Repeated Loading of Stabilized Recycled Aggregate Base Course
The fatigue behavior, resilient properties, and progressive accumulation of damage due to repeated flexural loads on a fiber-reinforced pavement base course material composed of cement-stabilized...
Better Salt Storage
Facing tighter maintenance budgets and stringent environmental regulations, many highway departments are designing and building innovative structures to store road salt. One such structure...
Journal of Composites for Construction
The Journal of Composites for Construction publishes original research papers, review papers, and case studies dealing with the use of fiber-reinforced composite materials in construction. Of special interest...
Catching Up on Composites
Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials...
New Construction Materials Proliferate in Japan
Research and development of new construction materials is extensive in Japan, and many new materials are being used in Japan now. The author analyzes the research environment in Japan,...
Large Deformation Theory Using Truncated Rotations
Today's aerospace industry has advanced to the point of using optimum design techniques in virtually all applications. In structural elements, orthotropic fiber composite materials have...
Damage Tolerance of Thin Composite Reinforced Membrane Structures
Structural performance of fiber reinforced flexible composite membranes, designed as pressurized shelters for space exploration, is investigated via computational simulation. An integrated...
Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [02/906]s...
Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...
Impulsive Punching of Fiber-Reinforced Concrete Slabs
The behavior of FRC slabs reinforced with polymeric fibers (polyacrylonitrile fibers PAN) and subjected to impulsive punching is analyzed here in order to clarify to what extent the fibers...
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...
Dynamic Response of Steel Fiber Reinforced Concrete
Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber...
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...
Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...
Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...
Nonlinear Analysis of Prestressed Concrete Structures
This paper presents a finite element model for the nonlinear analysis of prestressed concrete structures. The model can be used to analyze pretensioned or posttensioned, bonded or unbonded...
