Development of Automatic Optimum Design System M-FRAME

This technical report details the development of an automatic optimum design system named M-FRAME for frame steel structures by Mitsubishi Heavy Industries, Ltd. The report outlines the challenges faced with the previous steel frame cross-section minimizing method, which included manual data input and output, time-consuming calculations, and limited applicability. The newly developed system automates these processes, allowing for efficient design while considering both strength and assemblability of members. The report describes the methodology of the automated system, including the creation of a structural analysis model, optimization of cross-sections, and adjustments for member assemblability. It also presents a verification example demonstrating the effectiveness of the system in reducing the weight of frame steel structures and shortening design time. The report emphasizes the significance of automating the design process to enhance efficiency and broaden the application of the steel frame design method.
