Expert Tips : Posting a Bridge? Think about the Alternatives

Bridge load posting – identifying just how much weight a bridge can bear – is a matter of public safety and a way to safeguard vital transportation infrastructure. However, load posting is less straightforward than it may seem. Not posting a bridge can create safety issues for the motoring public, while posting makes transportation more difficult for large, heavy vehicles and the industries that use them. 

Webinar : Refined Analysis for the Optimum Design & Load Rating of Local Bridges

When talking about refined analysis, most engineers might think of using it for complex bridges and bridges that are beyond the range of applicability of the AASHTO LRFD formulas. While many favor a general philosophy of keeping the analyses simple to minimize errors, or to remain true to the accepted, proven engineering practices, it might come at a cost. Dr. Yanling Leng, lead bridge engineer from IMEG, will talk about why and how she has conducted refined analyses for the optimum design & load rating of normal local bridges

Expert Tip: Modeling of Bridges Composed of Simple Span Precast I Girders Made Continuous

Multi-span bridges composed of simple-span precast girders with continuous deck and diaphragms at interior supports have been a popular solution since the 1960s. State DOTs have employed various details and design methodologies. Understanding the details and designs of the continuity connections is critical for successfully modeling this type of bridge.
