| Abstract: | The Huiqing Huanghe River Highway Bridge at Qingzi Road is an extradosed bridge with rectangular shape pylons, rigid fixity of the pylons, girder and piers and with inclined diaphragms arranged in the main girder nearby the pylons. In this paper, the three-dimensional finite element model is established for the part of the rigid fixity to analyze the local stress at the part and particular efforts are made to analyze the influence of load action from the pylon to the main girder on the stress of segment No. 0 of the girder and also the effect of vertical and lateral prestressing load. |
