Short-term Construction Load Monitoring & Transverse Bending of the Bottom Slab on the I-280 Veteran’s Glass City Skyway

Abstract Details

2007, Master of Science, University of Toledo, Civil Engineering.
Located in Northwestern Ohio, the Veterans’ Glass City Skyway (VGCS) will carry I-280 over the Maumee River. Composed of 8,800-feet of precast, post-tensioned segmental box girders, the VGCS will feature a 1,225-feet cable stay span with a single plane of stays and was designed by FIGG Bridge Engineers, Inc. ODOT contracted the University Research Team (URT) composed of faculty and students from the University of Toledo and the University of Cincinnati to instrument the VGCS for health monitoring throughout construction. This research will address two important issues associated with the Maumee River Crossing project. First, in order to accurately predict live load response for a structure such as this, it is important to perform testing to determine elastic bridge response. In the case of the VGCS, the URT was presented with several opportunities to perform live load testing during the construction process. Data was recorded as the segment hauler used to transport segments traveled over the bridge. Additionally, prior to installation of the last two segments required for completion of the main span, the instrumentation was set to record data as the hydraulic truck cranes used for installation were repositioned from the tip of cantilever span to the opposing side of the final gap. This research will investigate the elastic bridge response during the aforementioned construction loads. Second, while performing a check of the proposed construction erection sequence, concerns arose from finite element modeling that there was a potential for the localized zones of high stress in the bottom slab caused by transverse bending. The URT installed gages in the bottom slab of two segments to monitor this behavior and resolve discrepancies in the finite element analyses. This research presents data collected from these segments at key construction stages.
