2012-9-1  The tensile reinforcement ratio is potentially an important factor that affects the ductility of the concrete beam section. There are few studies and test data on the ductility of over-reinforced HSC beams (Maghsoudi and Shari, 2009, Ho et al., 2010).

Strength and ductility of concrete beams reinforced with ...

2016-9-20  Ductility is a desirable structural property because it allows stress redistribution and provides warning of impending failure. Steel-reinforced concrete beams are under-reinforced by design, so that failure is initiated by yielding of the steel reinforcement, followed, after considerable deformation at no substantial loss of load carrying capacity, by concrete crushing and ultimate failure. This mode of failure is ductile and is guaranteed by designing the tensile reinforcement ratio to be substantially below (ACI 318 requires at least 25 %below) the balanced ratio, which is the ratio at which steel yielding and concrete crushing occur simultaneously. The-reinforcement ratio thus provides a metric for ductility, and the ductility corresponding to the maximum allowable steel reinforcement ratio provides a measure of the minimum acceptable ductility.

Flexural ductility and deformability of concrete beams ...

2012-1-25  High‐performance materials, such as high‐strength concrete (HSC) and high‐strength steel (HSS), are often adopted in tall buildings to reduce member size and save space. The use of HSC and/or HSS can significantly increase the flexural strength of concrete members but may also adversely affect the flexural ductility and deformability.

Curvature ductility prediction of high strength concrete beams

2018-4-25  From the structural safety point of view, ductility is an important parameter, a relatively high level of curvature ductility would provide to the structure an increased chance of survival against accidental impact and seismic attack. The ductility of reinforced concrete beams is very important, because it is the property that allows structures to dissipate energy in seismic zone.
