RISCyclic Compressive Behavior of Hybrid FRP-Confined Concrete
Publisher: ASCE
Abstract: The aim of this study is to define the cyclic axial behavior of hybrid FRP (fiber reinforced polymer)-confined concrete based on the results of an experimental study presented here. Two different types of fiber sheets with ...
Seismic Behavior of Repaired and Externally FRP-Jacketed Short Columns Built with Extremely Low-Strength Concrete
Publisher: ASCE
Abstract: Short columns with deficiencies of low-strength concrete and large spacing of transverse reinforcement are quite common in construction practice in many developing countries in seismically active regions. Therefore, it is ...
Cyclic and Monotonic Compression Behavior of CFRP-Jacketed Damaged Noncircular Concrete Prisms
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on rehabilitation/strengthening of damaged concrete prisms through external carbon-fiber-reinforced polymer (CFRP) jacketing. In order to evaluate the efficiency of the strengthening method on the damaged ...
Effects of Loading Rate and Duration on Axial Behavior of Concrete Confined by Fiber-Reinforced Polymer Sheets
Publisher: American Society of Civil Engineers
Abstract: In this study, 18 concrete cylinder specimens were tested either under uniaxial compression at different loading rates or exposed to sustained axial stresses after being jacketed externally with carbon-fiber-reinforced ...
Behavior of FRP-Retrofitted Joints Built with Plain Bars and Low-Strength Concrete
Publisher: American Society of Civil Engineers
Abstract: Two series of tests on eight full-scale exterior beam-column joint subassemblages built with plain bars and low-strength concrete were conducted. No transverse reinforcement was present in the joint cores. In the first ...
Cyclic and Monotonic Compression Behavior of CFRP-Jacketed Damaged Noncircular Concrete Prisms
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on rehabilitation/strengthening of damaged concrete prisms through external carbon-fiber-reinforced polymer (CFRP) jacketing. In order to evaluate the efficiency of the strengthening method on the damaged ...
Attempt for Seismic Retrofit of Existing Substandard RC Members under Reversed Cyclic Flexural Effects
Publisher: American Society of Civil Engineers
Abstract: Many existing reinforced concrete (RC) substandard structures in seismically active regions, designed and/or constructed improperly or constructed before up-to-date seismic design codes, are in urgent need of seismic ...
Effect of Corrosion on Bond Mechanism between Extremely Low-Strength Concrete and Plain Reinforcing Bars
Publisher: American Society of Civil Engineers
FRP Retrofit of Low and Medium Strength Circular and Rectangular Reinforced Concrete Columns
Publisher: American Society of Civil Engineers
Abstract: In this study, 68 reinforced concrete columns were tested under uniaxial compression after being jacketed externally with carbon fiber-reinforced polymer (CFRP) sheets. Forty specimens were cast using low strength concrete ...
Seismic Retrofit of Joints of a Full-Scale 3D Reinforced Concrete Frame with FRP Composites
Publisher: American Society of Civil Engineers
Abstract: Postearthquake reconnaissance studies show that the beam-column joints of substandard reinforced concrete buildings (particularly the corner joints) may fail to resist the demanded forces and deformations under severe ...
