In most cases, it's quite difficult for structural designers to perform many case studies when they plan a layout of earthquake resistant elements in a preliminary architectural design. So it would be helpful for them to know the characteristics of optimum designs, which can be regarded as standard design, with respect to the changes of numbers or layouts of earthquake resistant elements.
In this paper we present characteristics of optimum designs of steel plane frames with respect to layouts of multi-story braces through an examination of optimum designs by examining optimum design solutions of multi-story frames with various layouts of braces.
