RISMechanics of Damage and Constitutive Relationships for High-Strength Concrete in Triaxial Compression
Publisher: American Society of Civil Engineers
Abstract: A constitutive relationship for high-strength concrete (6 to 15 ksi) is developed based on the continuum damage mechanics. The bounding surface concept was employed in the formulations of the theoretical model. A comprehensive ...
Concrete Deterioration Mechanisms under Combined Sulfate Attack and Flexural Loading
Publisher: American Society of Civil Engineers
Abstract: The deterioration mechanisms of sulfate attack on concrete under sustained loading and wet-dry cycling were investigated based on micro and macroobservations. The mass fraction of sodium sulfate solution was 6.9%. Three ...
Comparison between Mechanical Properties of Dam and Sieved Concretes
Publisher: American Society of Civil Engineers
Abstract: This technical note presents the behavior of dam and sieved concretes in uniaxial tension and compression together with the effects of curing age on large size specimens of
Fracture and Tension Properties of Roller Compacted Concrete Cores in Uniaxial Tension
Publisher: American Society of Civil Engineers
Abstract: This paper deals with the behavior of roller compacted concrete (RCC) cores in uniaxial tension cored from a practical RCC dam. Properties included are tensile strength, peak strain, modulus of elasticity, fracture energy, ...
Experimental Study on the Bond Behavior of Reinforcing Bars Embedded in Concrete Subjected to Lateral Pressure

Smart Monitoring of a Super High Arch Dam during the First Reservoir-Filling Phase
Publisher: American Society of Civil Engineers
Abstract: The structural behavior during the first reservoir-filling phase is significant for evaluating a super high arch dam’s safety. This paper presents an in situ monitoring network of the Xiluodu Dam in Yunnan, China, including ...
Behavior of Concrete Driven by Uniaxially Embedded Shape Memory Alloy Actuators
Publisher: American Society of Civil Engineers
Abstract: The behavior of a concrete specimen uniaxially embedded with a shape memory alloy (SMA) wire actuated by electrical current is studied in this paper. The main factors influencing the axial strain of the concrete specimen ...
