Typology of the New York City Building Stock

This lecture will be presented by Dan Eschenasy 

Structural classifications of buildings are intended to reveal potential deficiencies in relation to various extreme loading conditions (wind, earthquake, flood or fire).  They need to reflect the type of structural systems, reliability of the basic materials and of the load paths mechanisms. Although the FEMA 547 methodology for classifying of buildings offers more categories than the IBC building code, it does not allow sufficient differentiation between older building systems. The presentation describes an effort to establish a New York City typology and inventory of buildings by combining FEMA building systems with classifications used by NYC firefighters to identify buildings.

1.5 PDH Credits
