This paper aims to developed SMC-Fractional algorithm, that is, enhances the performance of Sliding Mode Control(SMC) algorithm for pounding control of Multi-span bridges using MR-damper. The pounding control performance of SMC-Fractional algorithm has been evaluated in shaking table test on multi-span bridge. As a result of the experiment, the SMC-Fractional algorithm showed the performance od reducing the relative displacement of adjacent spans over other algorithms.
