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 become more complex in design. DIANA provides the tools to analyze both old and new.

Empower your vision for sustainable concrete structures

Simulate future bridge concepts 

Architectural design of bridges results in more complex shapes and the use of new durable materials. Assessment and prolonging life of existing bridges needs knowledge of nonlinear material behavior and the application of creative and modern strengthening techniques. These complex and challenging bridge engineering projects requires finite elements 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 phase.

Design optimization and long term assessment of the bridge structure

Reduce material and increase performance 

The extensive and model code based material models libraries in conjunction with the variety of element types, including 3D solid elements, and the possibility of performing a nonlinear calculation provides DIANA always a solution and calculates the (remaining) capacity of all bridges. Design tools in DIANA, ease these calculations by creating mobile loads, and calculating normative loading.
