ABSTRACT
Given the substantial economic, social, and environmental impacts of earthquakes, the need for an integrated framework for life-cycle seismic performance assessment of structures is increasingly recognized. This paper presents a comprehensive framework for life-cycle seismic resilience and sustainability assessment of reinforced concrete structures. The life-cycle costs and direct and indirect consequences of the earthquake are evaluated in terms of asset loss, time loss, life loss considering the number of casualty and fatality, environmental loss considering greenhouse gases emissions, and energy use. FEMA method for intensity-based and time-based loss analysis, economic input-output life-cycle assessment, and whole-building energy analysis (EnergyPlus) are adapted to quantify the life-cycle losses. The framework is implemented for commercial reinforced concrete buildings with and without shear walls. Results show that RC shear walls can significantly improve the resilience by reducing the monetary loss and downtime while improving the indoor air temperature fluctuation and reducing energy consumption.
