The seminar will be broken down into four main components:
- Historic steel framing
- Historic concrete framing
- Historic floor systems
- Historic curtain walls
Each section will discuss actual built structures between 1900 and 1950 and how they differ from current practice, how they can be identified on site, how they were noted on period drawings, how they can be analyzed using current codes, and how their safety compares to modern structure.
