Abstract :
Among the different lateral force resisting systems, shear walls are of appropriate stiffness
and hence are extensively employed in the design of high-rise structures. The architectural
concerns regarding the safety of these structures have further widened the application of
coupled shear walls. The present study investigated the optimal dimensional design of
coupled shear walls based on the improved Big Bang-Big Crunch algorithm. This
optimization method achieves unique solutions in a short period according to the defined
objective function, design variables, and constraints. Moreover, the results of the present
study indicated that the dimensions of the coupling beam in the shear wall significantly
affect the wall behavior by maximizing its efficiency which implies on its practical
application by considering the wall in the flexural model.
