摘　　要：对某钢结构电视塔倒塌事故进行了分析。通过事故现场的调查、结构构件的材料实测,对钢结构电视塔的倒塌原因做出了判断。通过对钢结构电视塔的有限元分析进一步验证了事故原因,并针对钢结构电视塔在设计中存在的问题及应注意的事项进行了分析。The paper analyzed the causes of collapse of a steel tower accident. According to the investigation of the accident and the experiments of structural materials,the judgments were made on the causes of the collapse of the steel structure TV tower. Through the finite element analysis of the steel TV tower,the paper further verified the causes of the accident. Moreover the existing problems in the design of steel structure TV tower were discussed,which could provide references for design and constructing of this kind of structures.
