WebAug 1, 2024 · Until the development of the first cracks, all specimens had roughly equal initial stiffness and deflections, indicating that initial stiffness is dependent on the stress paths from the STM regardless of the concrete being omitted in the proposed specimens.
WebMay 30, 2015 · This phenomenon of strength and stiffness reduction is commonly referred to as compression softening. Applying this softening effect to the strut-and-tie model, it is recognized that the tensile straining perpendicular to the strut will reduce the capacity of the concrete strut to resist compressive stresses. higher english sqa understanding standardsWebChrysostomou (1991) and Chrysostomou et al.
