Bridge Case Study: What a Contractor Needs to Know on an FRP Reinforcement Project
(ASCE, 4/1/2020 1)Civil works construction is now facing a transformational change with the growing implementation of fiber-reinforced polymer (FRP) materials as rebars and tendons for concrete structures. To avoid surprises and decrease ... -
Shear Strength Model for RC Beams with U-Wrapped FRCM Composites
(ASCE, 2/1/2020 1)The shear strength of reinforced concrete (RC) elements can be improved by applying externally bonded (EB) fiber-reinforced cementitious matrix (FRCM) composites. FRCM composites are generally U-wrapped around the cross-section ... -
Experimental and Analytical Investigations on Bond Behavior of Basalt-FRCM Systems
(ASCE, 2/1/2020 1)The results of an experimental investigation into the behavior of fiber-reinforced cementitious matrix (FRCM) composites made of basalt textile coupled to different inorganic matrices are presented and compared. Single- ... -
Joint Strength of Single-Bolted Pultruded GFRP Square Hollow Sections with Mechanical Inserts under Elevated Temperatures
(ASCE, 2/1/2020 1)The sensitivity of the joint performance of pultruded fiber reinforced polymer (FRP) to elevated temperatures has been known to limit the widespread application of FRP composites in civil construction. This paper presents ... -
Seismic Retrofit of Square RC Short Columns with Shear-Flexural Failure Mode via CFRP Composites Using Different Confinement Techniques
(ASCE, 2020)Short columns undergo larger drift ratios during earthquakes compared to ordinary ones, making them vulnerable structural elements if they are unable to withstand the demanded drift ratio and shear force without significant ... -
Behavior of FRP-Confined Circular RC Columns under Eccentric Compression
(ASCE, 2020)Strengthening of reinforced concrete (RC) columns through lateral confinement with a fiber-reinforced polymer (FRP) jacket has become an increasingly popular technique over the last two decades. To enable the safe and ... -
Durability of Commercially Available GFRP Reinforcement in Seawater-Mixed Concrete under Accelerated Aging Conditions
(ASCE, 2020)The effect of seawater used as mixing water in concrete on the long-term properties of glass fiber–reinforced polymer (GFRP) bars is the focus of this work. The durability of GFRP bars embedded in seawater-mixed concrete ... -
Monotonic and Cyclic Axial Compressive Properties and Modeling of Basalt FRP-Retrofitted Predamaged Short Columns
(ASCE, 2020)This study investigated the monotonic and cyclic axial compressive properties of predamaged concrete retrofitted using externally bonded basalt fiber-reinforced polymer (BFRP) sheets. Plain concrete cylindrical specimens ... -
Flexural Behavior of Concrete Beams Strengthened with Polyurethane-Matrix Carbon-Fiber Composites
(ASCE, 2020)Fiber-reinforced polymer (FRP) materials have been increasingly used for external strengthening of reinforced concrete (RC) infrastructure. However, the focus has been almost exclusively on epoxy-based composites, and other ... -
Predicting Flange Local Buckling Capacity of Pultruded GFRP I-Sections Subject to Flexure
(ASCE, 2020)Flange local buckling (FLB) of pultruded glass fiber-reinforced polymer (pGFRP) I-sections subject to flexure is investigated in this study. An experimental program, consisting of 62 four-point bending tests that had various ... -
Experimental Study on GFRP-Reinforced Concrete Closing Knee Joints
(ASCE, 2020)Knee-joints are a common element in concrete structures, which may be problematic when reinforced with glass fiber-reinforced polymer (GFRP) bars. GFRP bends are significantly weaker than the straight portions due to ... -
Performance and Durability of In-Plant Partially Cured GFRP Bent Bars in Steam-Cured Precast Concrete Elements
(ASCE, 2020)Glass fiber-reinforced polymer (GFRP) bent bars were used as shear reinforcement for precast/prestressed concrete box beams in Ontario, Canada. Differential scanning calorimetry (DSC) tests performed on the bent GFRP bars ... -
