Abstract: Taking the retractable roof structure of national tennis court “diamond stadium” as the analysis object， the effects of trolley horizontal stiffness on structure natural vibration characteristics and seismic responses of the retractable roof were comparatively studied using the finite element software SAP2000. The results showed that， with trolley horizontal stiffness decreasing， the structure natural period of vibration increased， and the horizontal and vertical displacements of the retractable roof track beam decreased， correspondingly. In addition， the trolley horizontal stiffness can influence the axial force of fixed roof and retractable roof bars， and it is more obvious on the fixed roof bars axial force. Therefore， the influence of the trolley horizontal stiffness should be considered in design and application of this kind of structure.

Key words: retractable roof, trolley, horizontal stiffness, natural vibration characteristics, seismic responses
