If your design is strong enough, the truck will be able to cross it successfully if not, the structure will collapse.
This simulation includes an animation of your bridge as it is loaded, first by its own weight and then by the truck driving across it. This test will determine whether your design is strong enough to carry its specified loads, which include the weight of the bridge itself plus the weight of a standard truck loading. Once the structural model is complete, click the Load Test Button to run a simulated load test of your bridge. You can define these properties as you design the structure-or just accept the default values and modify them later. Each member has its own unique properties-material, cross-section shape, and size. Each will cause the structure to carry load in a different way, and each has a different cost.Īfter defining the deck elevation and support configuration, create a structural model by drawing joints and members on the computer screen with your mouse. Using the Design Project Setup Wizard, choose from a variety of different deck elevations and support configurations for your bridge. How it works When you start up the Bridge Designer, you are presented with the project requirement-to design a steel truss bridge to carry a two-lane highway across a deep river valley. It is provided and intended for educational use only. The Bridge Designer is free and in the public domain. This software provides you with the tools to model, test, and optimize a steel highway bridge, based on realistic specifications, constraints, and performance criteria. The Bridge Designer will provide you with a realistic introduction to engineering through an authentic, hands-on design experience.
