DIANA, a Rocscience Company published an article exploring how DIANA FEA combines material modelling, structural monitoring, and load testing to evaluate bridge retrofits and uncover reserve capacity.

DIANA, a Rocscience Company, develops advanced nonlinear finite element analysis (FEA) software for structural, civil, geo-structural (SSI), earthquake, and energy engineering to analyse, verify, and design complex infrastructure and safety-critical structures. With decades of computational mechanics expertise and proven on landmark engineering projects worldwide, DIANA is recognised as a leader in advanced nonlinear FEA. Applications span reinforced concrete design, structural fire engineering, tunnelling and underground construction, seismic and dynamic analysis, dams, bridges, nuclear facilities, offshore structures, and emerging technologies such as 3D concrete printing. By combining scientific rigour with industrial reliability, DIANA enables engineers to tackle the most demanding nonlinear engineering challenges with confidence. Headquartered in The Hague, The Netherlands, DIANA joined Rocscience in January 2024.
