Silo

steel silo designer on the ShellFEA engine

Design and check a steel silo on a shell FEA model: wall courses, hopper, roof, product, wind and seismic loads, legs and anchor bolts.

Product pages are in English.

A question it answers

Can a 6 m wheat silo with 8/6/5 mm courses stand on eight X-braced legs, and which governs — shell buckling above the legs, the legs, the bracing or the anchor bolts?

What you put in

Plan shape and diameter, reference surface, wall courses (height, thickness, optional corrugation), hopper (half angle, outlet, thickness), roof, skirt or legs (count, tube, length, base fixity, panels, X / single / no diagonals, bracing tube, buckling curve), ring beam, vertical stiffeners, openings; material from the Twinsys library; stored product or liquid, fill level, load cases (self weight, filling, discharge, wind, seismic), editable combinations, partial factors and fabrication class, mesh; anchor bolts (count, size, bolt circle, base plate, embedment, concrete class); for a large-deflection run, the load combination, load control or arc-length, the number of load steps and the load factor λ.

What you get

3D shell (geometry, stress, displacement, deformed, section cut, exploded assembly, stored product) with legs, bracing, base plates, bolts and foundation; per-combination summary, ring-by-ring segments, stiffener and support-member tables with utilisation, analytic shell buckling per course, stress profile, geometry audit, support reactions, anchorage table, verdicts; mesh convergence study; PDF, XLSX and Markdown report; project JSON; and a large-deflection (GNA) run of one combination: whether the load factor was reached with a stable final state, the load–displacement curve against the linear response, and every member group's force and moment against its linear value.
