Simplified method for calculating the deformation of indeterminate structures with spring supports

In this paper, a simplified method was deduced for calculating the deformation of indeterminate structures with spring supports, according to the regular formula based on the principle of virtual work. The proposed formula, which is briefer, has the same form as the regular deformation formula for structures with rigid supports. Finally, an example was solved by the given formula and its correctness was proved by results of the finite element method.
