RISHybrid FRP Strengthening of Slender Steel Members for Buckling Control
Publisher: ASCE
Abstract: In this paper, the structural properties and behavior of slender steel members strengthened against buckling by a hybrid system of fiber-reinforced polymer (FRP) shells filled with self-consolidating grout (SCG), in the ...
Experimental Investigation of Short and Slender Rectangular Concrete Columns Reinforced with GFRP Bars under Eccentric Axial Loads
Publisher: ASCE
Abstract: In this paper, the experimental behavior of short and slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars under eccentric compression loading is presented. A total of 10 large-scale concrete ...
Novel Curve-Shape Sandwich Composites with Flexible Cores for Rehabilitation of Buried Infrastructure: Experimental and Analytical Studies Considering Geometric Nonlinearity
Publisher: American Society of Civil Engineers
Abstract: This paper presents findings from an experiment examining a novel curve-shape sandwich composite made of fiber-reinforced polymer (FRP) facesheets and flexible cores under transverse compressive loading. The curve-shape ...
Recycling Waste Gypsum Drywalls as Partial Cement Replacement in Concrete Exposed to Different Environmental Conditions
Publisher: American Society of Civil Engineers
Abstract: Recycled gypsum powder from waste drywalls is a new alternative that has been recently introduced for partial cement replacement in concrete for construction applications. It has been shown that the recycled gypsum, alongside ...
Strengthening Slender Reinforced Concrete Columns Using High-Modulus Bonded Longitudinal Reinforcement for Buckling Control
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a model for strengthening slender reinforced concrete columns. The proposed technique aims at controlling second-order lateral deflections using longitudinal high-modulus bonded reinforcement, thereby ...
Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Slender RC Columns Strengthened with a Novel Hybrid Strengthening System of External Longitudinal and Transverse FRPs
Publisher: ASCE
Abstract: In this study, the performance of slender circular concrete columns strengthened with a novel hybrid system of longitudinally bonded prefabricated fiber-reinforced polymer (FRP) laminates and transverse FRP wrapping is ...
Behavior of GFRP-Reinforced Concrete Members under Combined Bending Moment and Low Axial Load
Publisher: American Society of Civil Engineers
Abstract: This study examined nine concrete members reinforced with glass fiber–reinforced polymer (GFRP) bars, exploring the impact of combined bending moment and low axial loads. Three reinforcement ratios (1.7%, 2.5%, and 3.3%) ...
Assessing Compressive Properties of GFRP Bars: Novel Test Fixture and Statistical Analysis
Publisher: American Society of Civil Engineers
Abstract: This study investigates the compressive behavior of thermoset glass fiber–reinforced polymer (GFRP) bars across different grades, sizes, and length-to-diameter (L/db) ratios using a novel testing fixture. A total of 61 ...
