RISExperimental Investigation of GFRP-Reinforced and GFRP-Encased Square Concrete Specimens under Axial and Eccentric Load, and Four-Point Bending Test
Publisher: American Society of Civil Engineers
Experimental Study of High-Strength Concrete Columns Confined with Different Types of Mesh under Eccentric and Concentric Loads
Publisher: American Society of Civil Engineers
Abstract: A new idea is investigated in this study to reduce the cover spalling of high-strength concrete columns: installing relatively cheap materials such as household fly screen and wire mesh in the formwork of RC columns. Three ...
Optimum Design of Absorber for MDOF Structures
Publisher: American Society of Civil Engineers
Abstract: This paper discusses the optimum design of tuned mass damper (TMD) for seismically excited building structures. In the design process the multi degree of freedom structures are considered so that it makes improvement to ...
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 ...
Normalized Confinement Stiffness Approach for Modeling FRP-Confined Concrete
Publisher: American Society of Civil Engineers
Abstract: Passive confinement provided by fiber-reinforced polymer (FRP) jackets increases the compressive strength and axial deformation capacity of concrete. This study explains a normalized confinement stiffness approach to ...
Stress–Strain Behavior of Helically Confined RPC Columns Reinforced with Steel Fibers under Concentric Loading
Publisher: ASCE
Abstract: In this paper, an analytical stress–strain model is proposed that emphasizes the influence of steel fibers of different geometry and volume content on the behavior of the confined reactive powder concrete (RPC) columns. ...
Experimental Investigation on the Behavior of Hollow-Core Glass Fiber-Reinforced Concrete Columns with GFRP Bars
Publisher: ASCE
Abstract: Steel reinforcing bars, helices, and fibers in concrete columns are susceptible to corrosion, particularly in aggressive environments. This study experimentally investigated the use of corrosion-free glass fiber-reinforced ...
Cyclic Performance of GFRP-RC T-Connections with Different Anchorage and Connection Details
Publisher: ASCE
Abstract: This study investigated the effects of different configurations of connection reinforcement and anchorages on the cyclic behavior of glass fiber–reinforced polymer (GFRP) reinforced-concrete (RC) exterior beam–column ...
