RISAcoustic Emission Intensity Analysis for In Situ Evaluation of Reinforced Concrete Slabs
Publisher: American Society of Civil Engineers
Abstract: A three-story apartment building on the University of Miami campus in Florida, built in 1947 and scheduled for demolition in the spring of 2011, was used as a research test bed. Two identical strips of the one-way reinforced ...
Carbon FRP Strengthening of Doubly Curved Precast PC Shell
Publisher: American Society of Civil Engineers
Abstract: In this paper a recent rehabilitation project completed in Italy using carbon fiber reinforced plastic (CFRP) unidirectional sheets is examined. This technology was selected for the strengthening of a doubly curved, precast, ...
Expansive Grout-Based Gripping Systems for Tensile Testing of Large-Diameter Composite Bars
Publisher: American Society of Civil Engineers
Abstract: Tensile and shear testing to final fracture of large-diameter, fiber-reinforced polymer (FRP) composite round bars is often challenging because local stress triaxiality near the gripping ends can precipitate premature ...
Acoustic Emission Monitoring of Reinforced Concrete under Accelerated Corrosion
Publisher: American Society of Civil Engineers
Abstract: The development of techniques capable of evaluating the deterioration of reinforced concrete structures is instrumental to the advancement of structural health monitoring (SHM) techniques and service life estimate methodologies ...
Near-Field Microwave Detection of Disbond in Carbon Fiber Reinforced Polymer Composites Used for Strengthening Cement-Based Structures and Disbond Repair Verification
Publisher: American Society of Civil Engineers
Abstract: The use of carbon fiber reinforced polymer (CFRP) composites has been investigated in the past few years as a means to rehabilitate aging concrete structures. The detection of disbonds and delaminations between CFRP laminate ...
Acoustic Emission Historic Index and Frequency Spectrum of Reinforced Concrete under Accelerated Corrosion
Publisher: American Society of Civil Engineers
Abstract: The main cause of degradation for reinforced concrete (RC) structures is the corrosion of the steel reinforcement. Laboratory tests aimed at studying durability are typically accelerated to provide usable results within a ...
Strengthening and Load Testing of Three Bridges in Boone County, Missouri
Publisher: American Society of Civil Engineers
Abstract: Three bridges in Boone County, Missouri—Brown School Road, Coats Lane, and Creasy Springs Bridges—were selected for strengthening with carbon-fiber-reinforced polymer laminates in both shear and flexure. The objective of ...
Mechanical Characterization of Steel-Reinforced Grout for Strengthening of Existing Masonry and Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: Steel-reinforced grout (SRG) materials are thin laminates made of continuous fabrics of high-strength steel cords embedded within a cementitious matrix. This paper investigates the mechanical characterization of four SRG ...
Mechanical Characterization of Steel-Reinforced Grout for Strengthening of Existing Masonry and Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: Steel-reinforced grout (SRG) materials are thin laminates made of continuous fabrics of high-strength steel cords embedded within a cementitious matrix. This paper investigates the mechanical characterization of four SRG ...
Slip Modulus of FRP Sheets Bonded to Concrete
Publisher: American Society of Civil Engineers
Abstract: An analytical tension-stiffening model was developed for fiber-reinforced polymer (FRP) sheets bonded to reinforced concrete based on equilibrium equations and the assumption of linear behavior between bond stress and slip. ...
