Autodesk Structural Bridge Design provides an efficient workflow for the structural analysis and design of small- to medium-span girder/deck type bridges. One of the key selling points of the software is the automated traffic load optimization, which saves an enormous amount of time and money while providing an accurate solution.

It also performs real-time analysis to quickly get the information needed in order to make the next design decision — including monitoring adherence to design standards.

Closing the loop between analysis and design is critical in completing work more efficiently—and Autodesk Structural Bridge Design and analysis software bring the entire design process into one environment without the need for importing, exporting, and converting data.

Designs can be achieved with greater speed, and the single environment helps ensure that all data is consistent and accurate. Additionally, you can investigate more design options within the timescale and obtain the most cost-effective design solution.

The functionality of the product can be broken down into three very specific areas: section design, which deals with design on a section by section basis; the beam or girder design, which works with the whole length of the girder; and then the structural analysis.

The software is very flexible and can be used in many different ways but it is most powerful when a general iterative workflow is adopted to optimise the design process.

That workflow is as follows:

Define Structural Components
Start by creating the various structural components that you wish to design. These can be any number of structural sections and beam definitions.

Create Structural Model Layout
Then define the structural layout and geometry of the bridge deck, including setting out strings and carriageway definitions.

Assign Components to the Structure
The various structural components can then be graphically assigned to the structure thus providing the structural properties.

Create loading using optimisation techniques
Traffic load optimization and then structural analysis provide all the design movements and forces required for verification.

Verify components/design
Verification and code checking may highlight some deficiencies, in which case simple changes can be made to the component definition so that eventually, when re-analysis and re-verification are carried out, all code checks are satisfied.

Get Final Reports
At this point; the final report can be delivered.

Although this workflow is often demonstrated using a grillage type structural model, this workflow is essentially the same for simple models as well as more complicated models.

In addition to some quite advanced structural analysis capabilities, Autodesk Structural Bridge Design has unique and extensive code checking functionality that complies with the majority of international design codes.

At the end of any structural design process using computer software, a detailed report reports
provides you with an essential quality assurance document that you can deliver to your client. Autodesk Structural Bridge Design “detailed reports” are created in a style that provides an understanding of the engineering calculations involved and includes cross-referencing with clauses in the codes of practice.

The format of the reports are unique in that they take the form of hand-typed calculation sheets, giving you the ability to easily check the calculation and avoid any lengthy resulting post-processing that is typical for this type of work.

There are a number of reporting features that make any code cross checking more efficient. For example, for each check, the relevant part of the design code is referenced together with the formula in question followed by the actual calculation.

Autodesk has built on proven technology to offer this unique and powerful bridge design software.

With unique capabilities—including integrating loading, analysis, and code checking in a single environment, with the additional advantage of being able to generate full hand calculation style reports directly from analysis results—Autodesk Structural Bridge Design software gives you greater flexibility and efficiency with your small- to medium-span bridge design processes.
