Owing to environmental and loading effects, complex processes of deterioration in structural performance will be encountered in the maintenance and management of long-span bridges during their service life. Therefore, the method of evaluation for acquiring the current status and trend in the deterioration of bridge performance is important. To improve the efficiency and objectivity of performance evaluations, the concept of standardization can be introduced to specify each step of the evaluation procedure. This paper presents a preliminary research framework for the standardization of performance evaluations for the Taizhou multi-pylon suspension bridge, which has special structural characteristics. This study is a part of a three-stage project on data standardization, evaluation, and retention. First, a framework with six core modules (action, structure, response, performance, indicator, and target) is established. Second, the relationship between these core modules and the performance evaluation procedure is discussed. Third, the content (e.g., definition and hierarchy) of each core module is described in detail. Finally, three examples (saddle sliding on top of middle steel pylon, concrete carbonation, and performance of middle pylon under extreme actions) are provided to demonstrate how the framework can be applied in performance evaluations of long-span bridges.

生命周期性能评估的标准化及其在多塔吊桥中的应用

由于环境和负荷的影响,大跨度桥梁在使用寿命期间的维护和管理将遇到结构性能恶化的复杂过程。因此,获取桥梁性能恶化的现状和趋势的评估方法很重要。为了提高绩效评估的效率和客观性,可以引入标准化的概念来指定评估程序的每个步骤。本文提出了具有特殊结构特征的台州多塔吊桥性能评估标准化的初步研究框架。这项研究是数据标准化,评估和保留三个阶段项目的一部分。首先,一个包含六个核心模块(行动,结构,响应,绩效,指标和目标)。其次,讨论了这些核心模块与绩效评估程序之间的关系。第三,详细描述每个核心模块的内容(例如,定义和层次结构)。最后,提供了三个示例(鞍座在中钢塔架上滑动,混凝土碳化以及中塔在极端作用下的性能),以说明如何将该框架应用于大跨度桥梁的性能评估。
