Develop a comprehensive database of structural and non-structural building component repair.
In evaluating the life cycle environmental impacts of buildings, the contributions of seismic damage are rarely considered. This project developed and analyzed the largest known environmental impact database of building component seismic damage. By extending established methods of probabilistic seismic performance evaluation to include environmental impacts, a more comprehensive assessment of a building’s expected seismic performance can be evaluated.
To calculate the environmental impacts, data from Carnegie Mellon University’s Green Design Institute’s Economic Input-Output Life Cycle Analysis (LCA) database were connected to previously established repair cost estimate data. Environmental impacts, including embodied carbon, embodied energy, and other metrics, were calculated for the repair of nearly 800 building components under three or more different seismic damage levels. This database was developed to support the Federal Emergency Management Agency’s (FEMA) Performance Assessment Calculation Tool (PACT) as a part of FEMA Project P-58.
