摘要

摘要研究了冷弯型钢唇形槽钢在轴压作用下截面尺寸的参数优化问题。在预先确定型钢条宽、型钢厚度和型钢类型不变的情况下，考虑型钢的后屈曲行为和结构要求，建立了冷弯型钢截面尺寸优化问题。以冷弯构件承载能力最大化为目标函数。优化结果表明，冷弯型钢唇形通道具有最优尺寸。在相同耗材(条宽)的情况下，采用最优截面尺寸的钢唇形槽钢构件具有比生产厂家建议的构件更高的承载能力。

Cross-Section Size Optimization of Cold-Formed Steel Lipped Channel Structural Members Subjected to Axial Compression

Abstract A parametric optimization problem of cross-sectional sizes for cold-formed steel lipped channel structural members subjected to axial compression has been considered by the paper. An optimization problem is formulated to define optimum cross-sectional sizes of cold-formed structural member taking into account post-buckling behavior and structural requirements when stripe width, profile thickness and profile type are constant and specified in advance. Maximization of the load-carrying capacity of the cold-formed structural member has been assumed as purpose function. As optimization results cold-formed steel lipped channels with optimum dimensions have been obtained. Steel lipped channels structural members with the optimum cross-sectional dimensions have higher load-carrying capacities at the same material consumption (stripe width) comparing with the ones proposed by the manufacturer when the material consumption.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
