RISAxial Impact Resistance of FRP-Confined Concrete
Publisher: American Society of Civil Engineers
Abstract: This study investigates the impact resistance of fiber-reinforced polymer (FRP) confined concrete. Concrete cylinders were wrapped with carbon FRP (CFRP) or glass FRP (GFRP) with a varied number of layers and wrapping ...
Impact Behavior of FRP-Strengthened RC Beams without Stirrups
Publisher: American Society of Civil Engineers
Abstract: This study investigates the impact behavior of fiber-reinforced polymer (FRP)-strengthened reinforced concrete (RC) beams and FRP contribution to shear strength. Thirteen RC beams (1,500×150×250 mm) were tested against ...
Impact Behavior of FRP-Strengthened RC Beams without Stirrups
Publisher: American Society of Civil Engineers
Abstract: This study investigates the impact behavior of fiber-reinforced polymer (FRP)-strengthened reinforced concrete (RC) beams and FRP contribution to shear strength. Thirteen RC beams (
Strain Estimation of CFRP-Confined Concrete Columns Using Energy Approach
Publisher: American Society of Civil Engineers
Abstract: A new model is presented for calculating the axial strain of carbon fiber-reinforced polymer (CFRP)-confined concrete columns. An energy-balance approach is introduced to establish a relationship of the energy absorption ...
Stress Prediction Model for FRP Confined Rectangular Concrete Columns with Rounded Corners
Publisher: American Society of Civil Engineers
Abstract: The paper uses the membrane hypothesis to formulate the confining behavior of fiber-reinforced polymer (FRP) confined rectangular columns. A model was developed to calculate the strength of FRP confined rectangular concrete ...
Predicting Stress and Strain of FRP-Confined Square/Rectangular Columns Using Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: This study proposes the use of artificial neural networks (ANNs) to calculate the compressive strength and strain of fiber reinforced polymer (FRP)–confined square/rectangular columns. Modeling results have shown that the ...
Behavior of Precast Segmental Concrete Beams Prestressed with External Steel and CFRP Tendons
Publisher: ASCE
Abstract: Precast segmental concrete beams (PSBs) prestressed with external tendons have become increasingly popular. This type of structure takes advantage of both the segmental construction method and the external prestressing ...
Behavior of Ultrahigh-Performance Concrete Bridge Decks with New Y-Shape FRP Stay-in-Place Formworks
Publisher: ASCE
Abstract: This study proposes using glass fiber–reinforced polymer (GFRP) as a stay-in-place structural formwork for casting bridge decks with ultrahigh-performance concrete (UHPC). The GFRP stay-in-place formworks completely replace ...
Mechanical Properties of High-Strength Concrete Reinforced with Hybrid Basalt–Polypropylene Fibers under Dynamic Compression and Split Tension
Publisher: American Society of Civil Engineers
Abstract: Fiber reinforcement has been widely used to improve the performance of concrete under different types of loading. Among various types of fibers, a combination of fiber types, namely hybrid fibers, has been shown to be more ...
New Method of Strengthening Reinforced Concrete Square Columns by Circularizing and Wrapping with Fiber-Reinforced Polymer or Steel Straps
Publisher: American Society of Civil Engineers
Abstract: This study investigates three methods of strengthening existing reinforced square concrete columns under different loading conditions. Four groups of sixteen reinforced concrete square columns were made from normal-strength ...
