November 16, 2022 CSCE Monthly Dinner Meeting

Attendees may earn 1 New York State Professional 
Development Hour (NYS PDH) at this Event.

Please join CSCE at our monthly meeting at the Graduate Hotel at Quinnipiac University, on Wednesday, November 16, 2022. At this meeting, Michael P. Culmo, P.E., Chief Bridge Engineer, CHA Consulting, Inc., will give a presentation on the Design and Construction of an Innovative Non-Fracture Critical  Steel Straddle Bent at I-91 Interchange 29. The meeting co-sponsors are the CT Chapter of the ASCE Structural Engineering Institute and the ASCE Student Chapter at Quinnipiac University.

Presentation Overview

Straddle bents are often required in complex interchange designs.  Steel straddle bents have traditionally been built using a single cell steel box girder, which is considered to be fracture critical. A fracture critical designation requires more substantial and costly inspection techniques over the lifespan of the bridge. The presentation will focus on the development and construction of an innovative non-fracture critical steel straddle bent system. The 2018 AASHTO Guide Specifications for redundancy design will also be covered. This innovative design not only eliminates the fracture critical designation but can be fabricated at a lower cost. The new award-winning I-91NB Exit ramp bridge to the Charter Oak Bridge will be showcased in the presentation.
