摘要
桥梁结构的动力特性包括固有频率和振型,是结构动力分析、抗震分析的重要参数。运用有限元的分析方法,进行模态分析,建立有限元模型,对比分析了连续刚构与拱桥动力特性,发现了二者在频率、周期和振型的一些不同之处。
The dynamic characteristics of bridge structures include natural frequencies and vibration modes,which are important parameters for structural dynamic analysis and seismic analysis.Using the finite element analysis method,the modal analysis is carried out,the finite element model is established,and the dynamic characteristics of the continuous rigid frame bridge and the arch bridge are compared and analyzed,and some differences of the frequency,period and vibration mode of the two are found.
