连续梁桥施工阶段地震响应及抗震性能评估
Seismic Response and Performance Assessment of Continuous Girder Bridge
摘要
Abstract
Based on theory of cantilever construction,combined with a three cross continuous rigid frame bridge,with finite element analysis software,we select some complex construction phase as the research object,making calculation of seismic response and seismic performance.The results show that,when earthquake effects,rigid-framed girders' stress performance is better than that of continuous beam and the transition section is special; along the rigid-framed girder and transverse to the continuous girder,the seismic performance is good ; development of plastic transverse to the bridge is rapid,development of plastic of the complete bridge stage 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 construction,we need to pay attention to loads of rigid-frame bridge,strengthen the observation of side span closure phase.关键词
