Shear Strength of Reinforced Concrete Beams Using Recycled Coarse Aggregates without Stirrups
Author(s) Woosuk Kim, Thomas H.-K. Kang, Deuckhang Lee, Hajin Choi, and Yoon-Keun Kwak Abstract Given current environmental concerns, attention has been directed toward the use of recycled coarse aggregates (RCAs) as a substitute for natural raw materials...
Flexural Strengthening of Reinforced Concrete Beams Using Externally Bonded Polyurethane Carbon Fiber- Reinforced Polymer Composite Systems
Author(s) Titchenda Chan and Kevin R. Mackie Abstract Externally bonded carbon fiber-reinforced polymer (CFRP) composites are an effective method for flexural and shear strengthening and repair of reinforced concrete (RC) beams. In externally bonded CFRP...
Shear and Shear-Friction Strengths of Squat Walls with Flanges
Author(s) Ju-Hyung Kim and Hong-Gun Park Abstract Nine squat shear walls were tested under cyclic loading to investigate the effect of flanges on the seismic resistance of the walls. Test parameters were failure mode, flange thickness, reinforcement ratio,...

How Atlanta is Tackling its Traffic Crisis
In 2019, drivers around Atlanta spent more than 80 hours stuck in traffic; generating pollution and frustration, while costing each of them over USD $1,200 on average. The nightmare is typical of cities across the US, a country that’s seen infrastructure investment as...
Concrete Columns Reinforced with GFRP and BFRP Bars under Concentric and Eccentric Loads: Experimental Testing and Analytical Investigation
Author(s) Nouran Elmesalami; Farid Abed, F.ASCE; and Ahmed El Refai Abstract Twelve concrete columns reinforced longitudinally with fiber-reinforced polymer (FRP) bars were tested under both concentric and eccentric loadings. The investigated parameters were...
