What is stiff diagrams?

Stiff diagrams are a type of structural analysis tool utilized in engineering and construction fields to evaluate the stiffness and structural integrity of a system or structure. The diagrams depict the elasticity of a structure and are commonly used in conjunction with finite element analysis (FEA) software to optimize the design and performance of complex structures such as bridges, buildings, and aircraft. Stiff diagrams typically display the degree and direction of stiffness in a structure, as well as the locations of the most flexible areas that can be vulnerable to stress and strain. By analyzing a stiff diagram, engineers can identify potential weak points in a structure and make recommendations for structural improvements to ensure proper functioning and safety.
