Abstract
This study evaluates the environmental impacts resulting from the repair of earthquakeinduced damage, considering an older reinforced concrete (RC) frame representative of those built in Italy before the 1970s. Such impacts, expressed in terms of embodied carbon, represent a considerable component of buildings’ life-cycle embodied carbon in seismically-prone regions. Embodied carbon is a metric that measures the total greenhouse gas emissions associated with material extraction, manufacturing, transporting, construction, maintenance, and disposal. The seismic damage sustained by the case-study frame is first evaluated using the FEMA P-58 approach. Specifically, the frame’s nonlinear response is analysed against increasing groundshaking intensities, followed by estimating the damage incurred by its individual components via ad-hoc fragility models. Damage is then converted to embodied carbon by using consequence models specifically derived in this study for Italian structural/non-structural building components. This is accomplished by: 1) collecting environmental-impact data from Italian manufacturers of relevant construction materials and; 2) defining suitable structure-specific damage levels and the required repair work for every component. Results show that the embodied carbon induced by seismic damage throughout the case-study building’s life cycle might exceed 25% of that generated during its initial construction (pre-use phase).
