Abstract

It is of vital importance to incorporate sustainability and resilience in the performance-based decision-making of civil infrastructure under seismic hazard. However, a performance-based engineering framework utilizing component-level approach, integrating seismic loss, sustainability, and resilience in a multi-criteria decision-making (MCDM) is not yet extensively developed particularly for retrofit selection in a long-term perspective. This paper introduces a framework utilizing performance-based approach to couple seismic loss, sustainability, and resilience in decision-making framework for selection of different retrofit alternatives. A component-based probabilistic approach is developed for the seismic loss, sustainability, and resilience assessment in a long-term perspective. The resulting social, economic, and environmental consequences are converted to expected annual consequences (EACs) by considering the full range of seismic hazards, and are utilized as a multi-criterion in the technique for order preference by similarity to ideal solution (TOPSIS). The proposed long-term performance-based multi-criteria decision-making (PB-MCDM) framework considers five consequences, which include cost, casualties, equivalent carbon emissions, embodied energy, and repair time. Based on the illustrative example, it may be concluded that incorporating seismic sustainability and resilience in PB-MCDM approach in a long-term perspective can provide ideal solutions and better decision-making against retrofit alternatives.

考虑到长期损失,可持续性和复原力的地震危险性建筑物的基于性能的决策

抽象的

在地震危险下,将可持续性和复原力纳入基于绩效的民用基础设施决策中至关重要。但是,基于组件的方法,将地震损失,可持续性和弹性整合到多标准决策(MCDM)中的基于性能的工程框架尚未得到广泛开发,尤其是从长远的角度来看,这是为了进行翻新选择。本文介绍了一种基于性能的方法的框架,该框架将地震损失,可持续性和弹性结合在决策框架中,以选择不同的替代方案。从长期的角度出发,开发了一种基于组件的概率方法来进行地震损失,可持续性和复原力评估。由此产生的社会,经济,通过考虑所有地震危险因素,将环境后果转化为预期的年度后果(EAC),并通过类似于理想解决方案(TOPSIS)的优先顺序将其用作技术的多准则。拟议的基于绩效的长期多标准决策(PB-MCDM)框架考虑了五种后果,包括成本,人员伤亡,当量碳排放,具体能源和维修时间。根据说明性示例,可以得出结论,从长远角度将抗震性和回弹力纳入PB-MCDM方法中,可以提供理想的解决方案,并针对改造方案提供更好的决策。并且通过类似于理想解决方案(TOPSIS)在订单优先权技术中被用作多准则。拟议的基于绩效的长期多标准决策(PB-MCDM)框架考虑了五种后果,包括成本,人员伤亡,当量碳排放,具体能源和维修时间。根据说明性示例,可以得出结论,从长远角度将抗震性和回弹力纳入PB-MCDM方法中,可以提供理想的解决方案,并针对改造方案提供更好的决策。并且通过类似于理想解决方案(TOPSIS)在订单优先权技术中被用作多准则。拟议的基于绩效的长期多标准决策(PB-MCDM)框架考虑了五种后果,包括成本,人员伤亡,当量碳排放,具体能源和维修时间。根据说明性示例,可以得出结论,从长远角度将抗震性和回弹力纳入PB-MCDM方法中,可以提供理想的解决方案,并针对改造方案提供更好的决策。和维修时间。根据说明性示例,可以得出结论,从长远角度将抗震性和回弹力纳入PB-MCDM方法中,可以提供理想的解决方案,并针对改造方案提供更好的决策。和维修时间。根据说明性示例,可以得出结论,从长远角度将抗震性和回弹力纳入PB-MCDM方法中,可以提供理想的解决方案,并针对改造方案提供更好的决策。
