Session Information


In this presentation, we will explore moment connections and focus on the joint between a wide flange beam and an HSS column.  Attendees will gain practical knowledge of why designing and constructing with HSS columns is a smart and effective choice.  Using wide flange beams and HSS columns can lead to a very effective framing system, improve structural efficiency in two directions as well as being aesthetically pleasing.  During the hour, you will see discussion of:
The types of moment connections as well as their economic considerations.
Criteria to help the specifying engineer design which connection to use.
Current research that is being done.
Design examples and additional resource

KIM OLSON is Technical Advisor to the HSS Committee of the Steel Tube Institute. Kim has over 12 years of experience as a structural engineer, including her current position as a Structural Engineer at FORSE Consulting.  Currently she offers design, consulting and other support services to architects and engineers. Prior to joining the company in 2012, Kim worked for Bentley Systems, providing technical demonstrations and product trainings for structural engineers worldwide on each of the RAM structural engineering software programs. She was a practicing engineer at Martin/Martin, Inc. in Denver for seven years managing and designing a wide variety of structures including research laboratories, sporting grandstands, recreation centers and schools. Kim is a licensed professional engineer (PE) in the state of Colorado. As a technical advisor to the HSS Committee of The Steel Tube Institute, Kim works to educate architects and engineers on the many benefits of HSS. 


The presentation will focus on  performance based security design criteria for new transportation facilities, including bridges, tunnels, airline terminals, and rail stations. It will examine the risks from threats and hazards, typical mitigations to be investigated, and how security design integrates with the design required by codes.

JOSEPH M. ENGLOT, P.E., M. ASCE, is the National Director of Infrastructure Security and Associate Vice President of the HNTB Corporation, New York, NY.

Mr. Englot received both his Bachelors of Science Degree in Civil Engineering and Masters of Science in Civil Engineering from the Polytechnic Institute of Brooklyn in 1972. Mr. Englot joined HNTB in 2005 where he oversees projects that reduce the vulnerability of bridges, tunnels, and other types of transportation facilities to malevolent acts through the use of protective and physical hardening measures, as well as, projects to rehabilitate and retrofit bridges against the effects of natural hazards and general structural deterioration. He has extensive experience in damage assessment and disaster recovery of transportation facilities due to ship collision, truck collision, storms, and acts of terrorism.

At HNTB Mr. Englot has led projects to help the largest public transportation agencies in the US to prioritize their transportation infrastructure and identify and assess their most critical assets, based upon their vulnerability to multi-hazard events. He also recommends solutions to develop, design and construct effective mitigation projects to lower their risk to damage. He has developed practical and cost effective approaches to reduce the vulnerability of new facilities to multi-hazard events in the planning and conceptual design phases.

Prior to joining HNTB Mr. Englot spent 33 years with the Port Authority of NY & NJ, where he directed all structural design as Chief Structural Engineer for 10 years, followed by three years as Assistant Chief Engineer in charge of a multidiscipline design staff of over 350 Architects and Engineers. During that time he played a key leadership role in the disaster recovery programs from the 1993 and 2001 terrorist attacks on the World Trade Center, his agency’s headquarters.

Mr. Englot’s honors and awards include: 2001 ASCE Met Section Civil Engineer of the Year, 2003 FHWA and AASHTO Award of Gratitude (Participation on Blue Ribbon Panel for Bridge and Tunnel Security), 2004 New York State Society of Professional Engineers Government Engineer of the Year, 2005 ASCE Met Section Roebling Award, 2005 first recipient of the National Society of Professional Engineers PEGASUS Award (Professional Engineer in Government Award - Service in the United States), 2008 New York State Society of Professional Engineers Engineer of the Year Award, and 2012-2013 ASCE Met Section President.


Response of the Wrights Ferry Bridge across the Susquehanna, carrying west bound PA State Route 30, was measured during passage of a super load.  The super load consisted of a decommissioned transformer that was being transported from the Three Mile Island power plant in Dauphin County, PA to South Carolina.  The bridge structural arrangement employed repetitive five span modules of continuous/cantilever segments and pin-hanger articulation. The steel superstructure is a girder/floor beam system consisting of two main girders and floor beams with knee braces.  The end floor beam in each span extended up to the concrete deck slab.  The intermediate floor beams were of smaller depth and supported stringers on the top. The main girders extended up to the deck slab.  The superstructure was instrumented at a typical intermediate and end floor beam, at the floor beam of the approach span adjacent to the west expansion joint, at the main girders in the end span and pier supports, and at the pin-hanger connection.  The instrumentation and field measurements were conducted by the ATLSS Engineering Research Center of Lehigh University, and the instrumentation plan was developed in conjunction with Michael Baker, Jr. Inc. of Harrisburg, PA, who was responsible for engineering the move.  The structure was monitored during the passage of the super load in the wee hours.  In addition, the superstructure was also monitored under ambient traffic for three days after the passage of the super load.  The measurements provided valuable insight into the response characteristics of the bridge and the design assumptions for the structural behavior.

SOUGATA ROY, PhD, M. ASCE, is a Principal Research Scientist with the ATLSS Engineering Research Center at Lehigh University. Sougata received his Baccalaureate degree in Civil Engineering from the University of Calcutta in India, and Masters and Doctoral degrees in Civil Engineering from Lehigh University.  Dr. Roy is an expert in structural engineering with specialization in Fatigue and fracture of steel structures.  In addition to more than 14 years of experience in the academia, Sougata worked 11 years in structural engineering consultancy designing and managing large bridge engineering projects.  Dr. Roy regularly publishes in technical journals and conference proceedings, presents at national and international conferences and committee meetings, and is an active member of national committees included TRB AFH70:  Metal Fabrication Committee; and AISI/NSBA Design Advisory Group/Bridge Task Force, and ASCE/SEI Fatigue and Fracture Committee (current Chair).


Seven (236’-0” long) steel trusses weighing up to 250,000 pounds support the roof of the state of the art PPL Center located in the City of Allentown.  These provide an open space for the arena floor and seating below.  Come to learn about the challenges faced when erecting and bracing large trusses in a tight urban environment.   This presentation will also discuss truss erection analysis utilizing finite element modeling as well as field monitoring of trusses during erection.  

James D. Pudleiner PE, LEED AP, M. ASCE, serves as a Senior Project Manager for Alfred Benesch & Company and is based in their Lehigh Valley Office.  He received his BSCE from Lafayette College and MSCE from Lehigh University and has 31 years’ experience in building design and forensic investigations. Jim has also served as an Officer in the US Army Transportation Corps.  Recently he supervised the structural investigation of the Berks County Services Center. This included teaming with Lehigh University ATLSS for a  vibration evaluation of the 16 story steel frame structure induced by aerobic exercise and wing loadings. A SAP 2000 finite element model was created by Lehigh and used for both the vibration evaluation and structural analysis.

Michael S. Rohl, PE, M. ASCE, serves as a Project Engineer for Alfred Benesch & Company and is based in their Lehigh Valley Office.  He received his BSCE from Pennsylvania State University and has nine years of experience in building design and forensic investigations.  Mike recently provided structural analysis of the truss erection for the new constructed PPL Center in the City of Allentown which included creating a RAM Elements finite element model and field monitoring during erection.
