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. 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. It can be installed on either Windows or Mac computers. The winner of two major national awards for educational software development, the Bridge Designer has the “look and feel” of the computer-aided design (CAD) packages used by practicing engineers but is much easier to use. The Bridge Designer is a free educational software package designed to provide middle-school and high-school students with a realistic introduction to engineering through the design of a highway truss bridge.
