摘 要: 在实地测量的基础上,采用ANSYS有限元软件对具有斜立柱的古梁式桥——馀庆桥进行静力模拟分析,经过建模修正后,对该桥倾斜的立柱进行稳定性分析,获得了斜柱的倾角在8~12°左右时,立柱的极限荷载达到最大值,当立柱直立时,承载力将会降低将近40%. 当倾角小于8°或大于12°时,极限承载相应下降很快,并估算了该桥的承载力。
关 键 词: 结构力学;ANSYS建模;构件屈曲分析;结构力学分析;梁桥稳定性;结构实际运用

Abstract: On the basis of field measurement, the paper uses ANSYS finite element software to carry out a static simulation analysis on Yuqing Bridge, which has a style of ancient beam having inclined column. After modeling amendment, it gives a stability analysis of the inclined column and comes to a conclusion that it has its maximum ultimate load when the inclined angle is from 8° to 12° When the column is upright, the load capacity will reduce about 40%. The load capacity will reduce sharply when the inclined angle is below 8° or above 12° In the end, it estimates the load capacity of the bridge.
Key words: structural mechanics; ANSYS modeling; component inflection analysis; structural mechanical analysis bridge stability; practical application of structure
