This presentation will provide an overview on an ongoing NISTfunded project that is managed by the Applied Technology Council (ATC), concerning benchmarking of existing buildings evaluation methodologies. The objectives of this project are to: (1) benchmark ASCE 41 evaluation procedures with respect to the data recorded for reinforced concrete buildings subjected to actual earthquakes or tested experimentally on a shake table, and (2) compare the evaluation results predicted by ASCE 41 with Eurocode 8-Part 3, ATC 78, and New Zealand guidelines on evaluation of existing buildings. A suite of eight reinforced concrete buildings including moment frames and shear wall buildings, are identified where detailed design information as well as data from laboratory testing or field reconnaissance data of damaged buildings are available. The response of these buildings is assessed using the available evaluation methodologies, and the damage predictions from each methodology is compared against observed damage. The results will be used to identify strengths and weaknesses of each evaluation methodology in simulating the real performance of the building. The outcomes of this project would lead to recommendations for improving evaluation procedures in ASCE 41. This presentation will be followed by three case studies that are under development as part of this project.
