摘要
针对目前斜拉索阻尼器种类较多,斜拉桥选择拉索阻尼器无据可依的现状,根据建立斜拉索阻尼器评价指标体系的原则,在搜集阻尼器设计参数、征询有关专家意见的基础上,初拟阻尼器评价指标体系。然后采用主成分分析法对初拟的定量指标进行筛选,采用模糊优先排序法对初拟的定性指标进行筛选,从而得到斜拉索阻尼器综合评价指标体系。
Although there are multiple types of damper at present, little reference data can be found for cablestayed bridge to select damper for inclined cables. According to the principle of establishment of evaluation index system for the dampers, the preliminary evaluation index system of dampers was drawn up on the basis of design collected parameters and expert advices. Then the preliminary quantitative indexes were screened by principal component method for the evaluation index system, and fuzzy prioritization method was adopted for selection of the preliminary qualitative indexes. Thus a comprehensive evaluation index system of dampers of inclined cables was established.
