SeismoStruct is an award-winning Finite Element package capable of predicting the large displacement behaviour of space frames under static or dynamic loading, taking into account both geometric nonlinearities and material inelasticity.
Concrete, steel, FRP and SMA material models are available, together with a large library of 3D elements, such as nonlinear fibre beam-column elements, nonlinear truss elements, nonlinear infill panel elements, nonlinear masonry elements, nonlinear link elements, etc., that may be used with a wide variety of pre-defined steel, concrete and composite section configurations.
The nonlinear analysis solver of SeismoStruct, which features a fibre modelling approach and accounts for both geometric nonlinearities and material inelasticity, has been extensively used and quality-checked by thousands of users for more than ten years, as described in its Verification Report.
