    This paper presents a robust analytical model for a moment connection of concrete-filled fiber reinforced-polymer (FRP) tubes (CFFTs) to concrete footings. The CFFT connection is based on a simple approach of direct embedment ...

  • Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment 

    Publiher's vwesion: Sadeghian, Pedram, and Fam, Amir, (2011). Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment. Journal of Engineering Mechanics , 137 (5), 346-354 .doi: 10.1061/(ASCE)EM.1943-7889.0000231
    Concrete-filled fiber reinforced polymer (FRP) tubes (CFFTs) have been introduced as a new system for piles, columns and poles. A simple moment connection based on direct embedment of the CFFT into concrete footings or ...

  • Compressive Behaviour of Concrete Cylinders Reinforced with Glass Fiber Reinforced Polymer Bars 

    Current design standards ignore any contribution of glass fiber reinforced polymer (GFRP) bars in concrete in a state of compression. This paper challenged this convention by testing 30 cylinders of 36 MPa concrete to ...

  • Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers 

    Synthetic fibers, such as glass fibers, in the form of fiber-reinforced polymer (FRP) composites have been extensively used for the repair and strengthening of existing concrete structures in the past three decades. As ...

  • Durability of Flax FRPs Exposed to Accelerated Environmental Conditions 

    It is well known that synthetic fiber reinforcements, such as glass fibers, elevate the mechanical properties of polymer materials. Considering the synthetic material’s renewability challenges, natural fibers, such as flax ...

  • Effect of Fiber Orientation on Nonlinear Behavior of CFRP Composites 

    Publisher's version: Sadeghian, Pedram, Rahai, Ali R, and Ehsani, Mohammad R. (2009). Effect of Fiber Orientation on Nonlinear Behavior of CFRP Composites. Journal of Reinforced Plastics and Composites, 28 (18), 2261-2272. doi: 10.1177/0731684408092065
    Fiber orientation is one of the important parameters that affect strength and ductility of FRP-confined concrete columns. A number of studies have been conducted on various fiber orientations and wrap thicknesses, but have ...
