RISExperimental Investigation on Shear Behavior of FRP Prestressed Concrete Beams with Shear Reinforcements
Publisher: ASCE
Abstract: To evaluate the shear behavior of prestressed concrete (PC) beams with fiber-reinforced polymer (FRP) reinforcements, a total of seven large-scale beams, including one without stirrups, one with steel stirrups, and the ...
Shear Behavior of Post-Tensioned Concrete Beams with Draped FRP Tendons and without Transverse Reinforcement
Publisher: ASCE
Abstract: To investigate the shear behavior of post-tensioned concrete beams with fiber-reinforced polymer (FRP) reinforcements, six large-scale post-tensioned beams without transverse reinforcement and with a shear span-to-effective ...
Flexural Behavior and Design of Ultrahigh-Performance Concrete Beams Reinforced with GFRP Bars
Publisher: American Society of Civil Engineers
Abstract: The combination of glass fiber–reinforced polymer (GFRP) and ultrahigh-performance concrete (UHPC) to form structural members has generated significant interest due to their excellent durability and mechanical properties. ...
Design Equations for Flexural Capacity of Concrete Beams Reinforced with Glass Fiber–Reinforced Polymer Bars
Publisher: American Society of Civil Engineers
Abstract: The flexural failure mode of concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars changes from GFRP rupture to concrete crushing as the reinforcement ratio increases. Due to the uncertainties of material ...

Abstract: The flexural failure mode of concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars changes from GFRP rupture to concrete crushing as the reinforcement ratio increases. Due to the uncertainties of material ...
Calibration of Strength Reduction Factor for Reinforced Ultra-High-Performance Concrete Bridge Girders in Flexure
Publisher: ASCE
Abstract: Ultra-high-performance concrete (UHPC) has been widely used in bridges and other structures throughout the world. However, very limited studies have been carried out to address the strength reduction factor for reinforced ...
Experimental Investigation on Punching Shear Mechanism of Concrete Interior Slab-Column Connections without Shear Reinforcement
Publisher: ASCE
Abstract: The punching shear failure of reinforced concrete flat plates has puzzled researchers for a long time due to the complexity of the punching shear mechanism and the difficulty of direct measurements of the internal failure ...
Optimal Network Design of Battery-Powered Electric Feeder Bus with Determination of Fleet Size and Number of Chargers
Publisher: ASCE
Abstract: This paper investigates an optimization problem regarding feeder bus network design for metro stations, based on the wide use of battery-powered electric buses. To characterize the problem, a mixed integer programming model ...
Design Approach for Short-Term Deflection of Simple and Continuous Steel–Concrete Composite Beams Considering Interface Slip
Publisher: American Society of Civil Engineers
Abstract: Due to the slip occurring at the interface between the steel beam and the concrete slab, accurately predicting the deformation behavior of steel–concrete composite beams is rather complicated. In this paper, a mechanics-based ...
Prediction of Thermal Decomposition of Hardened Cement Paste
Publisher: American Society of Civil Engineers
Abstract: When exposed to elevated temperatures, various constituents in hardened cement paste will undergo decomposition, resulting in thermal damage of concrete. To better understand the thermal damage mechanism, it is essential ...
