Impacts of three kinds of connection ways of pylon-girder on seismic response of cable-stayed bridge

Three kinds of connection ways of pylon-girder and their realization in ANSYS are introduced.Taking Dongting Lake Bridge as example,finite element model is built utilizing ANSYS software.Changes of natural vibration frequency and seismic responses of cable-stayed bridge under various connection modes are comparatively analyzed,which has a certain reference value for design of cable-stayed bridge.
