An experimental study was conducted to examine for the structural behavior of coupled steel plate shear wall (Coupled SPSW) system what is formed by connection the two steel plate shear walls (SPSW) with a coupling beam. The variable of this study was the length of coupling beam. The testing results were showed that the strength and stiffness of specimen with shorter coupling beam were improved than those of other specimen. However there is no difference of the yielding mechanism.
