Abstract: According to the different width of the Pillars of continuous wall beam on many supports, this paper gives the accurate solution of the problem, which is based on theory of elastieity, with tie help of stress function expressed by series. Compare the solution with solution, we point oat why there is inccorrect stress distribution in some part of continuous wall beam in 3KeMo^kKH's solution. The solution of thie paper may be applied to design continuous wall beam on many supports.
