为了研究不同强度等级地震作用下连续梁桥的破坏模式及破坏程度,采用多级模糊综合评判方法建立连续梁桥的综合评估模型。根据连续梁桥的特点,利用连续梁桥各单元及各构件的破坏程度建立多个因素集,根据各因素的权重和评价标准,对多个因素集进行逐级评判,根据最大隶属度原则得到地震作用下连续梁桥的破坏情况,并通过等级参数评判法对不同地震强度下连续梁桥的破坏情况进行等级评判,得到连续梁桥破坏情况与地震强度之间的关系。最后,基于多级模糊综合评判方法对一座连续梁桥实例进行评判 |

In order to study the failure mode of continuous beam bridge under the various intensity of seismic, the synthetic evaluation model of the continuous beam bridge is established through the multi layer fuzzy comprehensive evaluation method. According to the characteristics of continuous beam bridge, multi factor gathers are set up with the destructing degree of elements and component of continuous beam bridge, then based on the weights and evaluation criterion of the indexes, the multi factor gathers are evaluated step by step, the maximum membership degree principle is used to determine the destruction of continuous beam bridge under the seismic, and the destruction of continuous beam bridge under the various intensity of seismic is evaluated using judgment method of hierarchy attribute, and the relationship between the destruction of continuous beam bridge and seismic intensity is obtained. Finally, based on the multi layer fuzzy comprehensive evaluation method, the fuzzy evaluation on a continuous girder bridge is conducted. |
