| 摘 要： | 以老庄河大桥为例,采用通用有限元ANSYS程序,分析了考虑行波效应下连续刚构桥的地震反应,并与一致激励作用下的结果做了比较。分析表明,不考虑行波效应对连续刚构的主梁不利,而对墩底内力偏安全。

| Abstract: | In this paper,by the example of Laozhuanghe bridge,the seismic response analysis for long-span continuous rigid-framed bridges considering traveling wave effect is simulated,and compared with the result under the coincident earthquake excitation.General purpose finite element program ANSYS is adopted in the analysis.The results indicate that the beams of continuous rigid-framed bridges are not safe when traveling wave effect is not considered and the abutments are opposite.The analysis presents direct instruction for engineering construction of the bridge. |
