Shear behavior and microstructures of confined colloidal suspensions
… electrostatic potential. Stress versus shear rate behavior is examined as a function of particle volume fraction, gap size, and shear history. Microstructures for systems at equilibrium and under shear are investigated by direct observation of particle configurations and by scattering …

Shear behavior of full-scale reinforced concrete members strengthened with anchored CFRP materials
Numerous studies on shear strengthening with CFRP material are reported in the literature. However, the majority of these studies were conducted on small-scale specimens that have little or no transverse reinforcement. A comprehensive review of the literature showed that without proper anchorage, …

Characterizing the Shear Behavior of Ultra-High-Performance Concrete through the Universal Panel Tester
The limited understanding of the shear behavior of Ultra-High-Performance Concrete (UHPC), especially under the effects of axial loads and varying scales, poses challenges to the formulation of reliable design models. Although UHPC is being utilized in structural applications, its complex behavior …

A Softened Membrane Model for UHPC (SMM-UHPC)
Understanding the shear behavior of Ultra-High-Performance (UHPC) is crucial to prevent undesired responses that could be induced by diagonal shear cracks. Hence, the ability of analytical models to predict shear responses of UHPC members is of paramount importance. This issue is addressed in this …
