| Abstract: | With the economic development of China,big-sized cold-formed steel structures are increasingly widely applied in construction work.Given the fact that steel structure is mainly designed based on overall stability,the study on the overall stability of steel structures is the emphases in the fields of construction safety.Based on a lot of data both at home and abroad,the effect of different types of initial imperfection on the overall stability of axial compressed cold-formed steel members is analyzed and at the same time some unsolved problems and future direction of the study are pointed out. |
