Abstract:
This Part 2 in a four-part series focuses on some of the key concepts and limitations impacting understanding and ability to make statements regarding safety of existing structures. It discusses how assessment of existing structures requires an understanding of the expected performance of the structure and how the performance is affected by the requirements of the building codes.
