The modulus of rupture is the maximum tensile stress reached in the bottom fibre of the test beam and calculations are based on elastic theory. Stress is assumed to be […]
EK558
Tension stiffening in a flexural member is the additional stiffness provided by the tensile stress in the concrete between primary flexural cracks. The tensile force in the concrete is transferred […]
EK530
Radial components of the bond forces are resisted by tensile stress rings in the concrete surrounding the bar.
EK474
Diffusion-controlled creep: A tensile stress increases the separation of atoms on grain boundaries that are normal to the stress axis, and the Poisson contraction decreases the separation of atoms on […]
EK273
Usually secondary flexural cracks are widely spaced, and one crack does not influence the formation of others. They are expected to occur under low loads, such as dead loads. When […]
EK129
The steel remains elastic while in linear range, and recovers perfectly on unloading. The limit of the linear elastic behaviour is often closely approximated by the yield stress. Beyond this […]
