Coupling beams are structural elements used to connect two or more shear walls. The
most common material used in the construction of coupling beam is reinforced
concrete. The use of coupling beams along with shear walls require them to resist large
shear forces, while possessing sufficient ductility to dissipate the energy produced due
to the lateral loads. This study has been undertaken to produce a computational model
to replicate the behavior of conventionally reinforced coupling beams subjected to
cyclic loading. The model is developed in the finite element analysis software
ABAQUS. The concrete damaged plasticity model was used to simulate the behavior
of concrete. A calibration model using a cantilever beam was produced to generate key
parameters in the model that are later adapted into modeling of two coupling beams
with aspect ratios: 1.5 and 3.6. The geometrical, material, and loading values are
adapted from experimental specimens reported in the literature, and the experimental
results are then used to validate the computational models. The results like evolution of
damage parameter and crack propagation from this study are intended to provide
guidance on finite element modeling of conventionally reinforced concrete coupling
beams under cyclic lateral loading.
