DEVICE FOR OPTIMALLY DESIGNING FRAMED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To improve the safety and reliability of a framed structure by using a device that executes an automatic calculation and can obtain an optimum solution thereby executing a highly precise optimal framed structure design in a real design problem that the number of pieces of design variable data is very large in an optimal designing device using a genetic search method. SOLUTION: This device for optimally designing the framed structure by using the genetic search method is provided with an approximate optimization calculating device using an approximate expression of discrete design variable data such as a framed member cross section size and a detailed optimization calculating device using the design variable data and constructs an optimization designing device for a framed structure by combing these two calculating devices. The approximate optimization calculating device using the approximate expression of the design variable data and the detailed optimization calculating device obtain the optimal solution of an excellent framed structure by continuously and automatically executing a two-stage optimization calculation no matter how many pieces the number of pieces of design variable data is.
