NIDA integrates second-order elastoplastic analysis, buckling assessment, construction simulation and visual post-processing, providing a trusted analysis and design platform for high-rise buildings, spatial structures and special engineering.
From modeling, solving to post-processing, NIDA provides advanced analysis solutions for real engineering practice
Systematic global analysis method based on nonlinear theory, considering structural P-Δ and P-δ effects to accurately reflect true structural response.
Considers system global and member local initial imperfections, one element per member, truly simulating structural stress conditions.
Considers member residual stress and material elastoplasticity, reduces stiffness accordingly, member design requires only section capacity check.
Compliant with China GB50017-2017, USA AISC360-2016, Hong Kong HKSC-2011, Eurocode3-2005 and other codes.
Differentiated editions for different engineering needs, from general professional analysis to specialized modules

Advanced analysis and design for general steel structures, covering the complete functionality of second-order elastoplastic analysis, buckling assessment and construction simulation, suitable for the vast majority of structural engineering projects.

Optimized for super high-rise and complex tall structures, enhanced with wind load, seismic time-history analysis and P-Δ effects, meeting the specialized analysis needs of high-rise buildings.
