Virtual work is the work done by a real force acting through a virtual displacement or a virtual force acting through a real displacement.
A virtual displacement is any displacement consistent with the constraints of the structure, i.e., that satisfy the boundary conditions at the supports.
A virtual force is any system of forces in equilibrium.
The principle of virtual work states, for bodies in equilibrium, for a small arbitrary displacement, the total work done by the system is zero.
In this method, the system is displaced through a small amount about a reference point and the work done by all the forces about the reference point is summed to zero to find the unknown reactions if any.
∴ The principle of virtual work states that, for a body to be in equilibrium, the virtual work should be zero.
