Abstract:
The modeling of concrete constitutive relationships in cyclic
compression has attracted a lot of research attention. In this study,
a normalized envelope stress-strain curve made for concrete in
uniaxial compression is mathematically derived. The compression
loops are formulated using a bilinear unloading path followed by
a linear reloading path based on thorough observations and calibrations
of available experimental data. The proposed normalized
model is calibrated against a set of experimental cyclic stressstrain
data. This model is shown to yield robust results by proving it
successful in capturing five other independent experimental cyclic
stress-strain curves. This proposed model may prove valuable for
the implementation and analysis of members subjected to cyclic
loading in numerical finite element analysis.
