About Tom Less

There are so many ways to help you save your time when you are working on your bridge project. One of the easy tips is renumbering of the nodes and elements.

Performing analysis on complex bridges, such as curved or flared structures, is a difficult task given the approximations and assumptions inherent in any modeling approach. Whether to use grillage analyses which run relatively quickly but are limited in their ability to model three dimensional effects or a full plate model to fully capture these effects but at added run times and model complexity is a challenge.

Generally a load rating is the bridge's ability to carry the live load for design and allowable legal vehicles, overloads, and determine weight postings. But how to perform the load rating of Curved and Complex Geometry Composite Steel Bridges in Midas Civil? Tom Less will expand the knowledge of Two-Dimensional/Grillage Modeling and Three-Dimensional Modeling and show how he sets up the inputs like rating design code, rating parameters, unbraced length, fatigue parameter, etc., for bridge rating design.
