摘要
针对直桥与弯桥的动力力学性能,采用大型通用有限元软件ANSYS分别对直线桥,连续弯桥,墩梁固结弯桥建立空间模型,并对其进行模态振型,频率分析,阐述了直、弯桥在动力力学性能上的差异,指出弯桥整体性不如直线桥好。
Aiming at the dynamic performances of the straight bridge and curved bridge,the author establishes the space model especially on the straight bridge,continuous curved bridge and pier beam consolidation curved bridge based on adopting large scale common finite element software ANSYS,and gets model vibration and frequency analysis on it,describes the differences of the dynamic performances between the straight and curved bridge,points out that the integrity of the curved bridge worse than straight bridge＇s.
