Abstract
A considerable number of tables and diagrams are available from which fixed-end moments, stiffness, and carry-over factors may be obtained for beams with variable moments of inertia. However, most of these tables and diagrams were prepared for symmetrical beams or for beams haunched at one end only. Since the combinations of shapes for unsymmetrical beams are limitless, it is obviously impracticable to tabulate data for but a limited range of shapes. The method proposed herein enables the_ designer to utilize the data available for beams haunched at one end only for the purpose of determining, quickly and accurately, the end moments, the stiffness, and the carry-over factors for unsymmetrical beams of any combination of shapes. This method should prove to be shorter than any other heretofore published for this purpose, with an accuracy equal to that obtained from the so-called “exact methods.”
