摘　　要：塔架结构在经历较长的服役期或由于其它原因而引起塔架结构的受力不利时,需要对其可靠度进行鉴定。本文根据塔架结构的受力特点,提出并完善了塔架结构主要失效路径识别的分层缩减法,并给出了相应算法。并在此基础上提出了塔架结构进行加固的基本原则。It is necessary that the reliability assessment should be processed for those steel tower structures going though long on active service or being in poor stress whenever for what reasons. This paper presents an alternative method of searching guide rules of critical failure paths based on the characteristics of steel towers. According to this method, the paper gives the principle of how steel tower structures get reinforced.

关 键 词：塔架结构 可靠度鉴定 主要失效路径
