1. Introduction
Recent developments in computer science and mathematics and the need for accurate solutions to problems have resulted in the development of analytical [1] and semi-analytical or discrete-continual methods [2]. For practical problems, it is often more suitable and easier to use an analytical solution than to employ an expensive finite element method (FEM)- based software. Analytical solutions employ a mathematical expression that yields the values of the unknown quantities at any location on a body (the total structure or physical system of interest) and are valid for an infinite number of locations. This property considerably reduces the computational complexity of the problem, an issue that requires special consideration in numerical methods [3]. Akimov and Sidorov [4] proposed an analytical solution to multipoint boundary problems for systems of ordinary differential equations with piecewise constant coefficients. Their method can be applied to continuous beams, which is a leading engineering problem. Beams in different types of bridges, continuous beams of multi-span girders [5], long strip foundations of buildings, and railroad and retaining walls [6] are includedinthis type ofproblem.Themostimportant applicationof the proposed method is an analytical solution to continuous beams onelastic foundations. The method can also be appliedto beams with structural or foundation discontinuities (changes in the elastic property or cross-section of the beam or stiffness of the soil) for beams without foundations by changing the coefficient matrix at the relevant interval.
