Abstract: This study provide software to calculate the seismic response of cable structures with viscoelastic dampers using the MATLAB program. At the same time, the interface communication software (PMI) between the PCS8000 controller and the calculation software is developed by using C++ Visual language to establish a bridge between the numerical substructure and the experimental substructure. The comparison between the results of mixed simulation and pure theoretical calculation based on MATLAB program proved that the experimental results are consistent with the pure numerical calculation, through which the reliability of hybrid simulation of cable structure is verified.
