- Abstract:
- Based on theory of cantilever construction,combined with a three cross continuous rigid framebridge,with finite element analysis software,we select some complex construction phase as the research ob-ject,making calculation of seismic response and seismic performance. The results show that,when earthquakeeffects,rigid-framed girders’stress performance is better than that of continuous beam and the transition see-tion is special; along the rigid-framed girder and transverse to the continuous girder,the seismic performanceis good; development of plastic transverse to the bridge is rapid, development of plastic of the complete bridgestage is rapid. Research suggests that,we need to strengthen the transition force changes of beam section,strengthen seismic design of transverse to rigid-framed bridge and along continuous beam bridge.During con-struction,we need to pay attention to loads of rigid-frame bridge,strengthen the observation of side span clo-sure phase.
