Abstract: An approximate optimization method is presented that is applicable to rectangular, two-dimensional multistory frames. Using special moment distribution techniques, the optimization of linearized frame weight is achieved for an infinite number of iterations. A closed-form exact formula makes it possible to avoid these iterations. Thus, when this program is used, a minicomputer with 4K memory can handle a four-story, four-bay frame subject to assymmetrical loading. The method is programmed in BASIC.
