![]() ![]() For a constraint to exist at a point, the boundary condition must indicate that at least one direction is fixed at that point.Ĭommon boundary conditions are shown in the table below. For a 2-dimensional beam, the directions of interest are the x-direction (axial direction), y-direction (transverse direction), and rotation. The boundary condition indicates whether the beam is fixed (restrained from motion) or free to move in each direction. Constraints are defined at single points along the beam, and the boundary condition at that point determines the nature of the constraint. ![]() ![]() Beam Calculator Constraints and Boundary Conditionsįor a beam to remain in static equilibrium when external loads are applied to it, the beam must be constrained. ![]()
