Michael Baker’s Approach to Complex Load Rating Workflow

Load rating is a type of project that most bridge engineers work on at one point. Although people often misunderstand it is easy to complete due to working on existing structure, finding accurate values like demand-capacity ratio, influence lines, and rating factors can be troublesome, especially when the bridge has unique or irregular geometries.

Michael Baker and MIDAS accomplished on various complex load rating projects successfully by combining Michael Baker's techniques and MIDAS' technology. Therefore, with various bridge project applications, Michael Baker engineers will guide you in handling complex steel and concrete bridge load rating projects with different approaches.

"Using no more than a spreadsheet on your end, but with powerful 3D FEA information in the background, overload permits for suspension, cable stay, arch, truss, rigid frame and other complex bridge types can be processed in less than a minute for many complex structures."
