摘　　要：本文研究了直立管式结构如烟囱、电线杆等的抗风防灾分析和经济损失估算。起始经济损失的弹性极限风压公式被推导,在实际风压大于弹性极限风压时经济损失估算公式被提出。由此直立管式结构的抗风防灾分析可以极快地得到。For vertical pipe structure such as chimney and wire pole, the wind-induced disaster and economic loss were studied. The elastic limit wind-pressure formula that begins to cause the economic loss of the structure is derived. The economic loss formula is also presented in the condition that actual wind-pressure is more than the elastic limit wind-pressure. Based on two formulae of elastic limit wind-pressure and economic loss, the analysis of wind-induced disaster for pipe structure is obtained rapidly.
