BeamDesign

This Finite Element Method (FEM) app is especially useful for civil engineers, mechanical engineers, architects and students who wish to design 1D hyperstatic frames. You can input and edit geometry, forces, supports, loadcases etc. The calculation results are performed instantly. Main features include: ✓ F, T and q (rectangular and triangular) loads ✓ Fixed and hinge connections at beam ends ✓ Fixed, hinge, roller and spring supports in any direction ✓ Imposed deflections ✓ Add or edit materials ✓ Add or edit sections ✓ Load cases and load combinations, including safety factors ✓ Moment, Shear, Stress, Deflection, Reaction forces and Unity checks Want to be part of the cutting edge FrameDesign developments?
