建筑钢结构论文（Building steel structure） The discussion on construction steel structure stability design of steel structure Abstract: the steel structure because of its light weight, high strength, high degree of industrialization in the construction engineering has been widely used on the other hand, because of the structure failure caused by the loss of accident casualties and property losses are often heard and lost the reason of failure is usually caused by defects in structure design. Through the summary of the concept, the principle and the analysis method of the stability design of the steel structure, combining with the practice of engineering design, this paper talks about the experience of the stability design of the steel structure. Keywords: steel structure stability design details is the stability design of steel structure engineering need to focus on the content of real life because of steel structural instability caused by the engineering accident case is more like the United States Hart Ford City stadium plane 92m * 110m grid structure in 1978 suddenly fell down to the ground due to buckling instability in 1988 our country has occurred 132M 0m * 18 steel truss for abdominal rod stability problems in the construction process of collapse accident on January 3, 2010 at Kunming Changshui International Airport 38m steel structure bridge suddenly collapsed caused 7 deaths and 8 people injured, 26 people were slightly injured because of the bridge steel structure support system of sudden instability 8m high bridge collapsed down. From the above case, it can be seen that the reason for the instability of steel structure is usually the unreasonable structural design and the structural design defects. The stability design of steel structure is the key to prevent the occurrence of such accidents. The difference between the strength of 1 steel structure stability design of the 11 concepts of strength and stability refers to the structure or a single component in the st
