Historically providing passage over obstacles such as valleys, difficult terrain, or bodies of water, modern-day bridges are expected to be longer, stronger, and inherently more complex in design. DIANA provides the tools to analyze both old and new bridges.
The architectural design of bridges results in more complex shapes and the use of new durable materials. Assessment and prolonging the life of existing bridges require knowledge of nonlinear material behavior and the application of creative and modern strengthening techniques. These complex and challenging bridge engineering projects require finite element analyses. DIANA’s extensive features and capabilities provide the most trusted platform for bridge designers to evolve their creativity and the complexities of their bridge structures, from design to construction, simulating future bridge concepts.
The extensive, model code-based material model libraries, combined with a variety of element types—including 3D solid elements—and the possibility to perform nonlinear calculations, ensure that DIANA always provides a solution and calculates the (remaining) capacity of all bridges. Design tools in DIANA facilitate these calculations by creating mobile loads and calculating normative loading.
