| 摘 要： | 针对某在建的150m跨径钢筋混凝土拱桥,利用开发的基于ANSYS的拱桥参数化建模模块,分别采用梁单元和实体单元创建有限元模型。在此基础上进行拱桥的特征值屈曲分析,并对拱轴线类型、桥面结构形式以及拱脚支承形式等影响因素进行了参数分析。分析结果表明:采用梁单元与实体单元进行结构离散,对于拱桥的特征值屈曲的计算结果影响不大。 |

| Abstract: | The finite element model with beam elements and the finite element model with solid elements by using the modules developed with the program ANSYS for a reinforced concrete arch bridge are presented with bridge's span of 150 meters.Eigenvalue buckling analyses are performed to those models.Those factors such as arch axis,deck type,arch springing type etc.that affect the eigenvalue are analyzed.The analysis' results indicate that the values of eigenvalue buckling analysis by using beam elements model or solid elements model have little difference. |
| Keywords: | bridge engineering reinforced concrete arch bridge modeling with parameters eigenvalue buckling analysis |
