In the technique, additional shear reinforcement (deformed steel bar: prefabricated reinforcing unit) is adhered to the surface of existing RC columns with RC sidewall by using polymer-cement mortar. Shear-loading tests of the RC columns with RC sidewall were conducted to clarify the structural performance of the columns with sidewall strengthened by polymer-cement mortar. The results suggested that the technique improved the shear capacity and ductility of the RC columns with RC sidewall, and clarified the mechanism of shear resistance of the strengthened columns with sidewall. Furthermore, a method of estimating the capacity (shear strength) and ductility of RC columns with RC sidewall strengthened by polymer-cement mortar was proposed by modeling the shear resistance mechanism.
