This new signature bridge is the technical and aesthetic centerpiece of the widening of the Sam Houston Tollway where it crosses the busy Houston Ship Channel. The precast segmental concrete cable-stayed bridge features a 1,320’ main span between pylons. It comprises twin structures connected at the main pylons that will be built in phases within the existing ROW. The project includes the demolition of a record-setting 750-foot span segmental concrete box girder bridge.

IBC 17-78: Analysis of The Global Stability Of Slender Piers Of High Bridges
Jose Simon-Talero, Ph.D., Torroja International, Madrid, Spain

A simplified method for taking into account the influence of the deck and the stiffness of all the substructure when calculating the effects of buckling of a slender pier of a high viaduct is presented. It is proposed using iterative first order calculations to take into account the effect of the geometric non linearity, the cracking of the concrete and the elastoplastic behavior of the materials (concrete and reinforcing steel).

 

Load Testing/Instrumentation

Wednesday, June 7; 9:00 a.m.—12:00 noon
Room: Woodrow A

IBC 17-79: Monitoring the Tappan Zee Bridge During Pile Installation for the Adjacent New NY Bridge
Patrick Mahon, P.E. and Robert Palermo, P.E., GZA GeoEnvironmental of New York, New York, NY

High capacity driven piles are being used to support two new bridges that will replace the Tappan Zee Bridge over the Hudson River. Some new piles were driven within 20 feet of the bridge. A monitoring system was required to evaluate the impacts of pile installation. The system was designed to use networked automated total stations with GPS base stations to overcome the challenge of measuring deflections on the bridge without fixed reference points.

IBC 17-80: Unforeseen Effects of Secondary Members
Natalie McCombs, P.E., S.E. and Samantha Kevern, P.E., S.E., HNTB, Kansas City, MO; Micah Drew, P.E., Mississippi DOT, Jackson, MS

This presentation will cover a case study for a two-girder bridge where lateral braces are used for wind loads on 16-foot deep box girders. Cracks have been observed in the floorbeam webs and welds at the upper lateral bracing connection. Placement of these braces was intended to carry wind load but the unique framing system combined with a mis-fabricated detail has created fatigue cracks for loads that were not likely considered in design.

IBC 17-81: Quantifying The Effects of Localized Corrosion Through the Use of Digital Imaging
Terrence Moran, George Mason University, Woodbridge, VA; David Lattanzi, Ph.D., P.E., George Mason University, Fairfax, VA

This paper reports on the development of a nondestructive evaluation technique for corroded steel. The goal is to better quantify the impacts of localized defects, such as pitting, on the ultimate strength of components. Tensile testing in conjunction with digital image correlation were used to calibrate an image analysis technique that quantifies pitted regions and provides a capacity reduction factor. Analysis indicates that the non-contact image analysis is capable of detecting localized failure modes.

IBC 17-82: Pre-installed Jacking System Prevents Shutdown of Existing Bridge during Adjacent Construction
Heather Scranton, P.E. and Jean Louis Locsin, Haley & Aldrich, Inc., Boston, MA; Mark S.Greenleaf, P.E., Commonwealth Engineers & Consultants, Inc., Providence, RI; Alec Smith, Haley & Aldrich, Inc., Bedford, NH

Given potential settlement of a nearby existing bridge during new bridge construction, a jacking system was installed at existing bents as an initial contract item. Instrumentation consisting of deformation points and strain gages on existing steel members were monitored remotely. During adjacent construction, several bents settled. When strain/movement neared action limits, jacking was implemented. Pre-installed jacks raised the bents quickly back into place without interrupting traffic and helped prevent bridge shutdowns and construction delays.

IBC 17-83: Structural Health Monitoring of the Hernando De Soto Bridge
Matthew Yarnold, Ph.D., P.E., Tennessee Technological University, Cookeville, TN; Justin Alexander, Cooper Steel, Nashville, TN; Tim Huff, Tennessee DOT, Nashville, TN

The Hernando De Soto Bridge has undergone substantial retrofits due to its proximity to the New Madrid fault line and importance to the region. Recently, a monitoring system was implemented which tracks the position of the structure and member force distribution before, during, and after a seismic event. The system provides actionable information to the owners regarding the current performance of critical bridge components and information for decision making after an extreme event.

Three structures between 360’ and 480’ each are founded on timber pile bents and require rehabilitation. In-depth condition ratings, including NDT to estimate pile lengths/embedment and the determination of capacities, justified the rehabilitation project that included protective pile jackets, deck resurfacing, and scour countermeasures consisting of stone mattresses. Construction is on-going.

 

 

Workshops

W-06: FRP Composites Impact to Sustainable Design of Concrete Bridges and Accelerated Bridge Construction

Time: 9:00 AM–12:00 Noon
Room: Magnolia 1

Presented By: American Composites Manufacturers Association

FRP composites are a proven material that has been used in over 500 bridges in North America during the past 2 decades. Consensus standards and codes have demonstrated and provided bridge engineers and owners with innovative and cost effective solutions to rebuild and retrofit bridge structures demonstrating long-term durability ranging from highly corrosive geographical regions from Florida to Canada. Composites features such as lightweight, corrosion resistance, and prefabrication have reduced assembly and installation time resulting in lower installation costs and delivery for new construction.  In retrofit and rehabilitation situations, composites are faster to install and require minimal disruption to the structure while in service that extends the service life of bridge structures.

This workshop will provide cutting edge material and product advancements on to design and specify FRP products to build steel free concrete structures, use of fiberglass rebar in the first ever cable stayed bridge, and the impact of composites on new techniques for accelerated bridge construction. Attendees will also learn 20-year durability performance of FRP composites and how this will apply to sustainable construction.

Attendees will learn about bridge design, construction, performance and testing using innovative FRP materials and products for concrete bridges, including: 1) bridges designed in Canada and Florida, 2) guidance on writing a special provision for an FRP strengthening project using industry guidelines, and 3) important special applications of bridge protection systems, long-term durability of FRP rebar in concrete bridges and structures and rapid replacement with lightweight bridge deck systems.
