AMSES Frame2D - Version 1.60 Amses Frame2D is a structural engineering tool used to calculate internal forces and displacements. Many structures can be analyzed: planar frames, continuous beams, trusses, cantilevers, and so on. Calculations are based on the finite element method. A graphical interface allows you to draw the structure, design load cases and actions, and calculate results within one single application. It supports true second order theory, solves simple problems quickly, has unlimited undo/redo capabilities, and has a unit conversion feature.
