Spliced I-girders span 172 ftover Jersey shore waterway

A new multi-span crossing over the SharkRiver in Monmouth County, NJ, is being con-structed with modified AASHTO I-Girders.The main span of 172' with two cantileveranchor spans of 25' and a drop in girder of122' is shown in the photo above.

The bridge replacement project is locatedon Route 35 near Red Bank and is beingconstructed in two phases in order to maintaintraffic in the busy shore area. The girdersbear on cast in place hammerhead piers.Erection is being accomplished with bargemounted cranes. Girders are delivered bytruck on the existing bridge for phase 1, whichwill be removed during the 2nd phase of theproject. The 2nd phase will be erected in asimilar fashion.

A total of 194 girders are required on the 15span structure. Spans vary in length from 98'to 113'. Girder sections vary in depth from 63"to 78" and in weight from approximately 52tons to 63 tons depending on the span. Thecantilever girders shown, vary in depth from78" to 120" over the bearing and weigh ap-proximately 110 tons. Concrete strength forthe girders was 5,000 psi for release of strand,and 6,100 psi ultimate at 28 days.

Temporary post-tensioning was used inthe cantilever girders for handling and ship-ping and removed prior to erection. Elasto-meric bearings support the drop in girders.Multi-rotational pot bearings support the can-tilever girders over the piers.

By using a drop-in girder with dapped ends,the designer was able to avoid temporarysupports for erection, that would have beenhigh and costly in an area with busy marinetraffic.

Construction sequence for spliced girdersThe above details are a hypothetical con-

struction sequence taken from NYSDOT draw-ing BD-PC25. They are shown for the de-signer, as an example of how three bulb teegirder sections could be spliced for a two spancontinuous girder bridge. The details are in-

cluded with bulb-tee details but would beapplicable for other sections such as I-gird-ers. The cast-in-place splice details show a250 mm wide butt joint with double shear keysand post-tensioning cables The joint is notmatch cast. ❏

State-of-the-artspliced girderbridges reviewedin PCI paper

The state-of-the-art for design and con-struction of spliced girder bridges is reviewedin a summary paper, published in the July-August 1992 issue of the PCI Journal. Pre-stressed spliced girder bridges are specifiedfor one or more of the following reasons:

• To increase the span capabilities of agiven section.

• To achieve continuity over piers.• To overcome transportation limitations

for girder segments

Spans in the range of 150' to 280' are madepossible by splicing, thus making pretensionedI-beams (or other sections) competitive withsteel in the medium span range traditionallyreserved for steel.

A survey aimed at gathering information onthe state-of-the-art of spliced girder bridgeswas conducted. Information on more than 40bridges, using several splicing techniques, isincluded. Even though the paper is now 10years old, important trends were noted in thesurvey. One of the most important was toeliminate all deck joints, including those atabutments by providing integral abutments.

The use of I-girders and bulb-tee girderswith optimum sections for negative and posi-tive moment is more common. The use ofhigh strength concrete and light weight con-crete deck panels is also noted in the report.The full report is available on the PCI websiteat www.pci.org. ❏

Deep girder bridges with long spans do notdevelop large positive restraint moments fromcreep and shrinkage according to a paperpublished in the July-August 2003 issue of thePCI Journal. It is possible to design girders forfull or near-full continuity for superimposedloads without these relatively large restraintmoments. A software program in conjunctionwith ACI 209R-92 provides a simple methodfor computing these restraint moments.

For shallower girders with expected girderages of 30 days or less, the authors recom-mend ignoring continuity and designing thegirders as simple spans. To achieve near fullcontinuity, girder age should be approximately90 days or older. ❏

Oneida LakeBridge, openedin 1960 with a320' center span

The Oneida Lake Bridge, opened for trafficin 1960 with a 320' center span and was oneof the first designs to use spliced girders andachieve continuity from abutment to abut-ment. The bridge is actually two three-spanbridges, one for north and one for southboundtraffic on I-81, which runs from Binghamton toCanada. The bridges are only 460' long, butthe center spans set a record when they wereconstructed over the Barge Canal in Brewertonat the west end of Oneida Lake.

There are six cantilever girders in eachbridge, which span 72' over the piers. The fivesuspended span center girders in each bridge,are 231' long and overlap the cantilever gird-ers for a 27' splice at each end. Counter-weights are located over the abutments toextend the center spans. Critical details areshown in the diagram below.

Girders cast on jobsiteAll of the 24 cantilever girders and 10

suspended span girders were cast on the jobsite by the general contractor. The end spanswere rolled from casting beds on each end totheir location on the abutments and piers.The suspended girders were rolled to a barge,floated to location, and then lifted as shown inthe photo above. The cantilever girders,which are 147' long and vary up to 14' indepth, each weighed 250 tons. The sus-pended span girders were 8'-6 in depth andweighed 222 tons.

Located on an interstate highway down-wind from Lake Ontario, the bridge is sub-jected to frequent and severe exposure eachwinter including heavy snowfall, multiplefreeze-thaw cycles, and frequent and heavyapplications of deicing salts, The bridge ap-pears to be performing well however.

Continuity of the designThe continuity of the design and the rela-

tively large mass of the bridge with CIP dia-phragms and abutment counterweights havemade the deck relatively watertight with littleevidence of leaking. Its scuppers are castiron; its bearings and downspouts are stain-less steel; and the wearing course is bitumi-nous concrete that was common at the time ofconstruction.

Bearings at the abutments and piers areunique, since they are positioned under cast-in-place diaphragms located between thecantilever girders. Short post-tensioningcables were positioned from the girders to thediaphragms and tensioned after the dia-phragms were cast. After post-tensioningand accurate positioning of the bearings, 24"diameter sand jacks, that were used for initialsupport of the girders, were opened to lowerthe bridge to the permanent bearings.

Terry Contracting was GCThe bridge is owned by the New York State

Department of Transportation. The Engineerwas Summers, Munninger and Molke fromAlbany. The General Contractor was TerryContracting Corp from New York City. ❏

RETURN SERVICE REQUESTED

Oneida Lake Bridge was astandoff by steel companies:

views by the editor

The Oneida Lake Bridge (see page 3) hadoriginally been planned, designed and ap-proved for letting by the New York StateDepartment of Public Works, NYSDPW, (be-fore DOT) as a tied arch steel span. No bidswere received on the first letting, since bidswould have exceeded the engineer's esti-mate of $1,963,000. No bids were receivedon the second letting also, since they wouldhave exceeded the engineer's new estimateof $2,204,000. It was a standoff betweenDPW and the steel companies, and the wordwas out, they would not bid unless the esti-mate were raised to at least $2,300,000.

Carol F Blanchard was Deputy Chief Engi-neer for Bridges for NYSDPW at that time andvery upbeat on prestressed concrete for thedepartment's bridge program. He reacted asyou might expect; authorized studies for aprestressed design, and a final design wassoon underway. Four bids were received on

the alternate design for prestressed concrete.According to ENR of March 31, 1960, bidsfrom the three lowest bidders were within$30,000 of each other, and the contract wasawarded to Terry Contracting Co from NewYork City for $1.7 million.

Eric Molke was the principal of Summers,Munninger and Molke, in Albany, who de-signed the alternate PS structure. Mr. Molkehad received his engineering degree andworked briefly in Austria before he emigratedto the US. He possessed the ability of all goodengineers to simplify complex problems andresolve constructible solutions. The OneidaLake Bridge was designed with a slide rule,before the days of computers or even calcu-lators. Ed Hourigan, our Tech Director whowas a design engineer in DPW at the time andlater became Deputy Chief Engineer himself,was assigned to check Mr. Molke's calcula-tions. For more details talk to Ed. ❏
