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...
Some General Remarks on the Structural Behavior and Load-Extension Characteristics of Coated Fabrics with Special Reference to PTFE-Coated Glass-Fiber Fabric
The understanding of fabric behavior, and of coated fabrics in particular, is essential for the design and analysis of fabric structures. Although many research papers have been published...
Polypropylene FRC In Steel Deck Composite Slabs
Engineers, testing laboratories, universities and metal deck manufacturers have studied polypropylene fiber reinforced concrete (FRC) and compared the results with similar slabs reinforced...
Cracking Behavior Comparisons Between Normal and Fiber-Concretes
A comparative study of the cracking behavior of plain- and polypropylene fiber concrete was performed. Both high- and low-strength concretes were studied. Maximum and average crack widths...
Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...
Fiberglas Reinforced Plastic Rebars in Lieu of Steel Rebars
Fiberglass reinforced plastics have recently been introduced in the market in the form of rebars for concrete reinforcement. The light weight, corrosion resistance and non-magnetic properties...
Flexural and Shear Moduli of FRP Beams
The analysis and design of structures of pultruded fiber reinforced plastic (FRP), constant cross-section, commercially produced, beams is discussed in the context of a shear deformation...
Effect of Temperature on the Load-Carrying Capacity of Fiber Glass Reinforced Plastic Beams
This paper describes an experimental investigation into the behavior of two T shaped beams made of fiber glass reinforcement and polyester or vinylester binders. Tests were performed at...
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...
Application of Fiber-Composites in Civil Engineering
Two potential applications of Glass-Fiber-Reinforced-Plastics (GFRP) in civil engineering type structures are investigated: (1) GFRP rebars in concrete beams; (2) strengthening of concrete...
Behavior of Externally Prestressed Concrete Girders
A new technique for prestressing concrete girders is presented. The girders are externally prestressed by epoxy-bonding fiber-composite plates to the tension flange of the cambered girders....
Fate and Effect of Carbon Tetrochloride and O-Xylene on Anaerobic Systems with Sulfate Reducing Bacteria
The fate and effects of o-xylene and carbon tetrachloride on methanogens and sulfate reducing bacteria were investigated using serum bottles. Up to 750 mg/1 of o-xylene did not cause any...
Isabella Project?Retrofit of Existing Tunnel
This paper explains conceptual methods of reinforcing and lining the section of the existing tunnel downstream of the three control gates to the exit portal and bifurcation for the power...
