Abstract:
Despite extensive research efforts directed toward the shear and torsional
behavior of concrete elements, torsion strength remains an unexplored area.
Numerous new materials are being used in construction as a result of advances in
concrete technology. The use of lightweight concrete, steel-fiber reinforced concrete,
and FRP-reinforced concrete are all kinds of advancements. The objective of the
current work is to enhance torsion strength prediction for these three aspects. A
summary of a series of power equation models for torsion strength based on a massive
experimental database of 346 beams tested under torsion is outlined. The model validation is discussed. The developed models are accurate while remaining simple for
design purposes.
