Statistically indeterminate beams such as continuous ones are commonly applied to practical engineering structures. A solution to such indeterminate beams, based on the Laplace transform, is presented in this report. A facilitating formula with loading functions and boundary conditions upon the beam was derived; moreover, four examples were used for testing the formula. The computational results from these examples show that this formula can easily and efficiently solve the problem of indeterminate beams, thereby evidently demonstrating the practicability of the presented method.
