Abstract
The increasing awareness of building sustainability in earthquake-prone areas constitutes a motive for investigating the influence of common seismic risk mitigation measures, such as structural retrofit, from a life-cycle environmental perspective. Accordingly, this study sheds light on the effects of reinforced concrete (RC) jacketing, a common retrofit strategy, on the life-cycle environmental impacts generated throughout the service life of a non-ductile RC frame constructed in Italy before the 1970s. Various layouts and configurations of retrofit configurations are developed to represent different design choices. The environmental impacts are expressed in terms of embodied carbon, a parameter that measures the overall greenhouse gas emissions associated with the life stages of a system (e.g., manufacturing, construction, maintenance, disposal). The lifecycle embodied carbon includes the earthquake-induced emissions evaluated by characterising the seismic damage sustained by the structure and then converting it to embodied carbon using suitable consequence models. The other life-cycle component is the embodied carbon of retrofit intervention, for which a simplified expression that relies on the retrofit layout and geometric features is derived. Results show that the life-cycle embodied carbon of the as-built structure constitutes 70% of that related to initial construction. The use of RC jacketing could reduce this percentage to as low as 43%.
