Dynamic property parameters such as periods, vibration modes, damping ratios, the amplificatory coefficients of seismic action were obtained. On the basis of the experimental study, the software ANSYS was adopted to make modal analysis. The results show that reinforced concrete silt hollow shear wall structure is a new form of structure which is between frame structure and traditional shear wall structure. The experimental results accord with ANSYS simulation results well.
