RISOptimization of the Joint Structure Between Asphalt Concrete Core and Concrete Plinth in Earthen Dams Based on the Response Surface Method
Publisher: American Society of Civil Engineers
Abstract: The joint structure between the asphalt concrete core and the concrete plinth is a critical and vulnerable part of the asphalt concrete core dam (ACCD). Shape parameters of the core–plinth joint structure are directly ...

New Method for Investigating Crack Development in Concrete Using an Ultrahigh-Speed Camera
Publisher: American Society of Civil Engineers
Abstract: Cracks are ubiquitous in concrete materials and can destabilize a concrete structure, regardless of size or type. This study focuses on the cracking behavior of main and branching cracks in concrete. Compression tests and ...
Damage Process of Roller-Compacted Concrete Based on Combined Action of Freeze–Thaw and Triaxial Compression
Publisher: ASCE
Abstract: Roller-compacted concrete (RCC) structures are often destroyed by coupling damage of freeze–thaw and complex loads in cold conditions, resulting in degradation of the mechanical properties of the RCC. In this study, the ...
Dynamic Splitting Tensile Damage Characteristics of Steel Fiber–Reinforced Fly Ash Concrete Based on Acoustic Emission Technology
Publisher: American Society of Civil Engineers
Abstract: AbstractThis paper investigates the effects of steel fiber dosage, fly ash replacement rate,
and loading rate on the dynamic splitting tensile mechanical properties and acoustic
emission (AE) time-frequency characteristics ...
