Bentley Structural and TriForma were used for design review sessions in open forum settings. Simulations were used to communicate with stakeholders and ensure scheduling and phasing between the championships.
Joe Tognoli, vice president, principal bridge engineer for T.Y. Lin International, presented the finalist project for the David Kreitzer Lake Hodges Bicycle/Pedestrian Bridge, the “longest stress ribbon bridge in the world.” The $8.8 million bridge opened May 15, 2009 in San Diego and is owned by the San Dieguito River Park. The project site is 1,000 feet to the west of the bridge for I-15, and extends 55 miles, terminating in the Volcan Mountains. The purpose of the bridge is to connect trails shown on the north side of the lake to trails on the south side for bicycle commuters, eliminating a 9-mile detour.
The river park wanted a unique design, and the engineer had to come up with a selection type for the bridge that was compatible with the goals of the river park and the area. It had to provide a lake crossing of 1,000 feet. Threatened and endangered species included the Coastal Calif. Gnatcatcher, least bell’s vireo, and Southwest willow flycatcher.
With the goals of having a low environmental and visual impact, the stress ribbon bridge design was selected because it is an eco-friendly design, can span over 300 feet and only two piers would be needed, and it would provide low impact to the lake area. It uses precast panels and segmental construction.
The deck is very thin. The lake fluctuates from wet to dry, so the architect came up with a concept that the bridge should float in wet conditions and be “nesty” during dry conditions. Ultimately, it has three spans at 330 ft. with 16” thick deck, with a 6 foot sag.
At each end of the bridge is a large abutment anchorage and a drape over intermediate piers. It is essentially a suspension bridge with cables embedded, and it is necessary to have rock on both ends and use tie downs to secure the abutments. This work was all done in MicroStation. Types of analysis conducted included stress analysis, stressed Eigen value analysis, pedestrian vibrational analysis and dynamic wind analysis.
Tognoli said there are only five stress ribbon bridges in North America.

The second day of the event featured executive roundtables, designed to get a dialog started between attendees. In one roundtable, a lively conversation ensued in which customers spoke out on what they felt were the deterrents to integrated project delivery adoption.
In another roundtable, a customer problem was addressed, with the added support of a Power Point to show off all the new exciting features from the SELECTSeries that might help address that problem.
This was the second Bentley event I’ve attended this year: the first being SmartGeometry 2009 held in San Francisco, which showcased the users of GenerativeComponents technology. Bentley is planning to reinstitute the BE Conference next year May 17-21, dubbed “Be Together,” in Philadelphia, its location before they began holding it in Baltimore.
For journalists, hotel, airfare and some meals for this event were covered by Bentley Systems.
