Building codes and code enforcement have for a century provided a sound framework for design of new structures. But as sustainability of the built environment has become more important now than ever, it is necessary for engineers to be able to rehabilitate existing structures in a way that is compatible with the code but which also treats the existing structure appropriately. Using examples from practice this course will explore key factors to consider when evaluating and rehabilitating existing structures and will discuss the application of various approaches to understanding existing structural systems. Specific code compliance triggers will be discussed in the context of the examples. The presentation will include examples of obsolete or archaic (not-designed) systems, including cast iron and wrought iron, timber, unreinforced masonry, and early concrete.
