A method based on a solution in the form of a series of characteristic functions is suggested for calculating the influence coefficient for beams on elastic foundation. Using this method, a set of influence lines is obtained for the beams with free ends, such that the design of beams on elastic foundation is brought within the easy reach of an ordinary structural engineer.
