Modeling of reinforcement global buckling in RC elements
(Elsevier, 2014)
Buckling of longitudinal reinforcement in reinforced concrete (RC) columns or walls is commonly seen
with a length equal to the spacing between stirrups (local buckling), but experimental observations have
shown that the ...
Low-cycle fatigue behaviour of reinforcing bars including the effect of inelastic buckling
(Elsevier Ltd, 2018)
Low-cycle fatigue life of Grade 300E and 500E reinforcing bars including the effect of buckling is evaluated. Low-cycle fatigue tests are carried out on un-machined specimens subjected to constant axial strain loading with ...
Experimental study of the residual fatigue life of reinforcement bars damaged by an earthquake
(Springer Netherlands, 2019)
Reinforcing bars removed from structural walls that belonged to a damaged building during the 2010 earthquake in Chile are studied under low-cycle fatigue testing. Damage of such walls was characterized by concrete crushing ...
Effects of strain gradients in the onset of global buckling in slender walls due to earthquake loading.
Global buckling of slender walls, reported only in a few laboratory tests before 2010, became a critical issue in design of reinforced concrete buildings after it was observed following the 2010 Mw 8.8 Chile earthquake and ...
Seismic behavior of slender reinforced concrete walls
(2014)
Residential reinforced concrete buildings performed well during the 2010 M,, 8.8 Maule, Chile earthquake. However, brittle damage was observed in reinforced concrete structural walls. The most frequent observed damage in ...
On micro-buckling of unidirectional fiber-reinforced composites by means of computational micromechanics
(Latin Amer J Solids Structures, 2016-12)
Micro-buckling of unidirectional fiber-reinforced composites is investigated in this paper by means of an explicit representation of a geometrically imperfect fiber within the context of kinematical and material non-linear ...
Effect of axial loads in the seismic behavior of reinforced concrete walls with unconfined wall boundaries
(Elsevier Sci Ltd, 2014)
About 2% of Reinforced Concrete (RC) buildings taller than nine stories suffered serious damage in structural walls during the 2010 Chile earthquake. The observed damage involved mostly crushing of concrete, buckling of ...
