Abstract:
Finite element models are currently used for the assessment of structural behavior, which
becomes more accurate and reliable. Since conducting the full experimental test is very
expensive and time consuming, it is better to use numerical method to investigate the behaviors
of structure because the efficiency of the model can be evaluated by the experimental result
and it shows good agreement with the experimental tests.
In this study a non-linear finite element analysis with ABAQUS software package has been
taken to investigate the response of reinforced concrete exterior shear wall –slab connection
subjected to cyclic loading. The structural responses such as load carrying capacity, energy
dissipation, ductility and stiffness degradation has been studied.
Using developed models parametric study have been done to investigate the effect of
connection type, aspect ratio of thickness of slab to thickness of shear wall (Ts/Tw), aspect
ratio of height of shear wall to effective width of the slab (H/We) and concrete grade on the
load carrying capacity, energy dissipation, ductility and stiffness degradation of exterior
reinforced concrete shear wall-slab connection. A total of 22 models have been used to
investigate the parametric study.
The results show that the exterior shear wall-slab connection with U-type connection have
high load carrying capacity than the other connection type, as the aspect ratio of Ts/Tw
increases the load carrying capacity and energy dissipation capacity increase, as the aspect
ratio of H/We decrease or as effective width of the slab from shear wall increase the load
carrying capacity and energy dissipation capacity decreases and as concrete grade increase
the load carrying and energy dissipation increases.
