What's this calculator used for?
This free calculator can be used by Structural Engineers for Finite Element Analysis of 3D structures. This tool can be used to calculate bending moment, shear force, node reaction forces and measure deflection for frame structure. Input section properties for beams and columns and apply fixed end, pin jointed and free degrees of freedom to the structure. Add point loads or distributed loads to get started analysing the frame.
