Abstract
Abstract：Aimed at removing instability and failure associated with thin-walled compressive bar in engineering, this paper features appreciable impact of each factors, based on orthogonal experimental method and by analyzing the bi-nonlinear stability of thin-walled compressive bar, selecting sectional di- mension of I-shaped cross-section as factors of ultimate load of thin-walled compressive bar, and perform- ing the orthogonal experimental design. Flange width exerts the greatest effect on stability ultimate loads, followed by flange thickness. The paper ends with the development of mathematic model of thin-walled compressive bar by multiple linear regression theory and design of section optimum, thus giving a 30%. increase in section and ultimate load.关键词
