Description:
Bob Cisneros & Sue Steele will be sharing their experiences as bridge engineers with High Steel Structures, LLC. Their presentation will have a two-fold focus:
  • Measurement, metrology and survey measurement tools used in the building of bridges (girder, truss, arch) including two Pennsylvania structures. The handling of assembly challenges such intended fit condition (no-load, steel and full dead load), weather-induced settlement, compound tolerances and thermal ratcheting allowance will be discussed.
  • Implementation of the new 2017 AASHTO “Guide Specifications for Wind Loads on Bridges During Construction”. Current exposure, gust, and wind speed-up criteria, as well as their distribution to windward, leeward and interior girders will be compared to earlier, ASCE/NHI-based methods that High’s engineers have utilized during the picking, setting & stabilization of bridge structures during erection. Pennsylvania criteria such as BD 620M (Steel Girder Bridge Lateral Bracing Criteria) & BC 772 (P/S Concrete Primary/Secondary Beam Bracing) will be included.
Picking up where earlier ASCE-SEI sessions left off, after illustrating sample applications of these concepts, the presenters hope to open the floor up to frank discussion and mutual learning with attendees.

Emergency Repair of the PA/NJ Turnpike Connector Bridge - 1.0 PDH

Location:

Description:

In January 2017, a fracture in the top tension chord of a four-span continuous deck truss was discovered, forcing the immediate closure of the bridge connecting the PA and NJ Turnpike’s over the Delaware River at Bristol, PA.  Within hours, emergency repair designs were underway along with the fabrication of temporary splices.  Concurrently, the construction of emergency shoring/jacking towers had begun, and a plan was being developed to assess the 14 spans of deck trusses comprising the PA and NJ approaches. The bridge was reopened less than seven weeks after the date of fracture.  Learn how the jacking and restoration of the chord made a difference, as well as what sorts of material and nondestructive tests conducted were conducted.

Presenter:

Jim Stump, PE - Mr. Stump is the Bridge Engineer Manager for the Pennsylvania Turnpike Commission. Jim has been employed by the Commission for 25 years and has 29 years of transportation related experience. As the Bridge Engineer Manager, Jim oversees the Commission's Bridge Program which includes the design, rehabilitation and inspections of over 1100 structures as well the Commission's five sets of tunnels. Jim graduated from Penn State University with Bachelor’s Degree in Civil Engineering.
