Abstract

ABSTRACT Resilient bridge infrastructure is a fundamental component of an uninterrupted transportation system. Thus, assessing the resilience of bridge infrastructure against natural hazards is crucial for transportation agencies. Therefore, the main objective of this study is to develop an integrated framework for analyzing the bridge infrastructure resilience against seismic hazards. The Dempster-Shafer method has been incorporated with the Best Worst Method to achieve this objective and accommodate uncertainty. At first, various resilience criteria have been identified based on an extensive literature review. The weights of the resilience criteria have been determined using the Best Worth Method based on the response provided by the experts. After that, the Dempster-Shafer rule of combination has been used to assess the seismic resilience of a highway bridge by proposing a Bridge Resilience Index. This proposed resilience framework can support transportation agencies in taking effective strategies against seismic hazards.

桥梁基础设施抗地震灾害弹性分析的集成框架

弹性桥梁基础设施是不间断交通系统的基本组成部分。因此，评估桥梁基础设施抵御自然灾害的能力对交通运输机构来说至关重要。因此，本研究的主要目的是开发一个综合框架来分析桥梁基础设施对地震灾害的恢复能力。Dempster-Shafer方法已与最佳最差方法相结合，以实现这一目标并适应不确定性。首先，根据广泛的文献综述，确定了各种弹性标准。根据专家提供的响应，采用最佳价值法确定了弹性标准的权重。在此基础上，运用Dempster-Shafer组合规则，提出了桥梁回弹性指数，对某公路桥梁的抗震回弹性进行了评价。这个拟议的复原力框架可以支持运输机构采取有效的战略来应对地震灾害。

期刊介绍： Sustainable and Resilient Infrastructure is an interdisciplinary journal that focuses on the sustainable development of resilient communities. Sustainability is defined in relation to the ability of infrastructure to address the needs of the present without sacrificing the ability of future generations to meet their needs. Resilience is considered in relation to both natural hazards (like earthquakes, tsunami, hurricanes, cyclones, tornado, flooding and drought) and anthropogenic hazards (like human errors and malevolent attacks.) Resilience is taken to depend both on the performance of the built and modified natural environment and on the contextual characteristics of social, economic and political institutions. Sustainability and resilience are considered both for physical and non-physical infrastructure.
