摘　　要：结合某冷弯薄壁型钢结构住宅实例,采用大型通用有限元软件ANSYS建模,运用零阶法、一阶法对梁、柱构件截面进行优化分析。结果表明,与原设计相比,优化分析后工程的用钢量得到了大大的减少,这不仅有利于钢材的节约,带来可观的经济效益,而且有利于冷弯薄壁型钢结构住宅在我国的推广和应用。Based on a cold-formed thin-walled steel structure example, using the universal finite element software ANSYS building model of actual engineering and using method of zero order and first order to beam and column section for optimization design. Then we can obtain：Then we can obtain：Compared with the actual engineering steel quantity, which greatly reduces, saves steel quantity and brings considerable economic benefit. The high cost which block development is no longer a main factors. It＇s propitious to the development of cold-formed thin-walled steel structure housing in our country.
