Seismic Design validates earthquake-resistant design requirements — structural irregularity controls, capacity design, storey drift limits, and seismic loading — against the active seismic code. TBDY 2018, IBC, and Eurocode 8 with its regional annexes are supported alongside national standards across multiple countries.

Steel Design covers member-level design checks — tension, compression, flexure, shear, combined forces, and fatigue — alongside composite member design, general design requirements, and structural analysis. Each check is validated against the active steel code, including AISC 360, Eurocode 3 with its regional annexes, BS 5950, and TSC 2016.
