If the usefulness of a structure depends on the working stresses produced at working loads, then these stresses should be checked. This involves no particular problem for beams with constant moments of inertia, but if the case of a continuous beam with abrupt changes in the moments of inertia between supports is considered, the computations become very cumbersome. The object of this thesis is to facilitate the checking of the working stresses of such a structure. Graphs are provided to eliminate many of the computations necessary for the application of the moment distribution method in the finding of moments, and hence stresses, at working loads.
