Threaded Bar Reinforcing Systems
This lecture will be presented by Steven Bongiorno
There has been a recent increase in the use of threaded bars as reinforcement for concrete building structures. They are typically provided as part of a larger system comprised of complimentary hardware for connections, anchorage and erection. As concrete structures continue to become taller and more complex, the use of such reinforcing systems will become even more prevalent. As such, it is important that designers understand and appreciate the unique features of threaded bars in order to maximize the benefits of their use as reinforcing in concrete structures. It is also critically important that designers, inspectors and end users understand the mechanical behavior and limitations of threaded reinforcing bars to ensure that they are being specified and installed appropriately for a given application.
This lecture will cover the basic features of treaded bars systems, their typical applications and benefits for concrete building structures and the limitations of their use in certain applications and under certain conditions. This will be a hands-on presentation, with various threaded bar components utilized and available for examination and audience participation throughout.

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.
Dan Eschenasy is the Building Department’s Chief Structural Engineer. Under the executive direction of the Commissioner he performs with great latitude structural assessments, forensic investigations and provides advice in emergency situations.
On the evening of 9/11 he was charged with organizing the engineering response to the tower’s collapse. In this capacity he worked closely with SEAoNY volunteer engineers and this contribution earned him the SEAoNY Honorary Membership.
Dan has authored papers on construction accidents and several of his forensic investigations of fatal accidents have been published. He is a member of several ASCE committees, including the Committee for Structural Condition Assessment and Rehabilitation of Existing Buildings. In this area he has published papers on the inspection and condition evaluation of existing buildings, facades and retaining walls.
Dan has received a Diplomat Engineer (BS/MS) degree from the Construction Institute of Bucharest and a Master of Science in Management from the Sloan School of MIT. In 2014 he was made a Fellow of the Structural Engineering g Institute (SEI). Presently he serves as a Director of the Structural Engineering Certification Board.
