When talking about refined analysis, most engineers might think of using it only for complex bridges and bridges that are beyond the range of applicability of the AASHTO LRFD formulas. For the design and load rating of normal local bridges, many favor a general philosophy of keeping the analyses simple to minimize errors, or to remain true to the accepted, proven engineering practices. However, this might come at a cost to our nation and may not foster the most effective use of limited resources.<\/p>\n
In a recent webinar with Midas, I argued that refined analysis is the future for bridge analysis\u2014including for the optimum design and load rating of normal local bridges\u2014and is a must-have skill for bridge engineers of today.<\/p>\n
A properly and efficiently executed refined analysis can provide substantially better information about a bridge and allow for more cost-effective design. While a refined analysis is not guaranteed to improve a load rating enough to avoid a posting, it is always a more accurate representation of a structure, compared to approximate methods.<\/p>\n
