Triaxial Compression Performance Research of Steel Slag Concrete on the Unified Strength Theory

open access: yesApplied Sciences, 2020
To better explore the mechanical properties of steel slag concrete (SSC) under triaxial compression, true triaxial tests were performed on SSC with three replacement ratios (30%, 70%, 100%) by a servo-controlled setup (TAWZ-5000/3000).

Plasticity Model for Hybrid Fiber-Reinforced Concrete under True Triaxial Compression [PDF]

open access: yesJournal of Engineering Mechanics, 2014
Based on the experimental background of 75 true triaxial compression tests conducted on cubic specimens, a plasticity constitutive model for hybrid steel-polypropylene fiber-RC (HFRC) is developed in this study, aiming to accurately predict the strength and deformation of HFRC under various loading scenarios.
