Abstract
This paper presents the results of a study undertaken to determine the feasibility of using the digital computer to make the time-consuming calculations necessary to construct moment-load interaction curves. A strip method of numerical integration was set up to solve the equations of equilibrium for the members, this method allowed a generalization of the procedure to all shapes of cross-section. In setting up the problem for the digital computer, it was not convenient to work with the actual stress distributions. Instead, it was found that the actual stress distribution could be represented by three linear stress distributions having the same stress gradient. Load- and moment-functions were computed from these stress distributions and the actual load and moment in the section were determined from these load- and moment-functions. Load- and moment-functions for some 86 different conditions for T-, angle-, and channel-section members were determined using the digital computer. The great number of additional computations required to construct the interaction curves once the load- and moment-functions are available renders the digital computer method reported herein of questionable use. Further study of the problem could possibly produce methods by which these additional computations could be made by the computer and thereby make the method more efficient and useful.
