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,...
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...
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...
Durability of Reinforced Concrete Beams Externally Strengthened with CFRP Laminates under Harsh Climatic Conditions
Author(s) Nasser Al Nuaimi, Ph.D.; Muazzam Ghous Sohail, Ph.D., M.ASCE; Rami Hawileh, Ph.D., M.ASCE; Jamal A. Abdalla, Ph.D., F.ASCE Abstract This paper addresses the durability of reinforced concrete beams strengthened with carbon fiber-reinforced polymer...
Behavior of Square Slender RC Columns Strengthened with Longitudinal FRP Sheets Subjected to Eccentric Loading
Author(s) Davood Mostofinejad; Mohammad Sadegh Salimian; Maryam Taherirani; and Masood Noroozolyaee Abstract In this study, the grooving method was employed to strengthen reinforced concrete (RC) columns with longitudinal fiber-reinforced polymer (FRP) sheets,...
Durability Assessment of 15- to 20-Year-Old GFRP Bars Extracted from Bridges in the US. II: GFRP Bar Assessment
Durability Assessment GFRP Bars Author(s) Ali F. Al-Khafaji, S.M.ASCE; Rudy T. Haluza, S.M.ASCE; Vanessa Benzecry, S.M.ASCE; John J. Myers, F.ASCE Abstract A multilaboratory investigation into the durability of glass fiber–reinforced polymer (GFRP) bars...
Durability Assessment of 15- to 20-Year-Old GFRP Bars Extracted from Bridges in the US. I: Selected Bridges, Bar Extraction, and Concrete Assessment
Author(s) Vanessa Benzecry; Ali F. Al-Khafaji; Rudy T. Haluza; Charles E. Bakis, A.M.ASCE Abstract Glass fiber–reinforced polymer (GFRP) bars have been used in concrete structures as an alternative to steel bars due to their noncorrosive behavior. However, due...
Improving Seismic Behavior of Existing Multicolumn RC Bridge Bents Using Low-Damage Retrofit Strategy
Author(s) Mohammad Jafarkarimi and Mohammad Khanmohammadi Abstract Implementing a low-damage design (LDD) approach to improve the seismic behavior of existing RC bridge bents as a retrofit strategy is the main focus of the present study. Experimental and...
