Highlights An integrated decision model is presented for resilience and sustainability assessment. The framework includes three modules, four sets of criteria, and three decision models. Damage to non-structural components increases expected number of injuries markedly. In MCDM, benefits of sustainable design can outweigh other performance shortcomings. Proposed diagrid form achieved better scores than original one in decision analysis.
Abstract Resilience and sustainability are both key criteria in risk-informed decision analysis of structural systems. However, a comprehensive framework which incorporates both in a multi-criteria decision-making (MCDM) process is yet to be developed particularly for more recent structural systems such as diagrids. This paper introduces a coupled resilience- and sustainability-based decision-making framework for seismic design and rehabilitation of building structures. FEMA method for intensity-based and time-based loss, downtime, and casualty estimation are used to evaluate seismic asset, time, and life losses. Economic input-output life-cycle assessment method is adapted to evaluate the environmental loss due to earthquakes, as well. Aiming to study the trade-off between various economic, social, and environmental impacts of earthquakes, an MCDM framework is proposed based on analytic hierarchy process, multi-attribute utility theory, and technique for order preference by similarity to ideal solution (TOPSIS). The framework is used to study the resiliency and sustainability of archetype steel diagrid buildings in a high seismic region. Six scenarios with different objectives including minimum asset, time, life, or environmental loss and maximum resilience are studied. A survey is conducted to find the weight factors for each criterion for each scenario. Results show that in an MCDM framework, the benefits of sustainable design techniques can outweigh possible shortcomings due to structural configuration and performance.
