摘要
对在设计基准期内可能承受动力荷载作用的结构，避免结构产生共振或类共振现象，是结构设计的一个重要内容。针对承受动力荷载作用的化工结构物，考虑外部侵蚀介质对结构自振频率的影响，讨论了结构服役若干年后承受动力荷载的结构基于频率约束条件的耐久度衰减规律，对结构设计及评估具有一定的参考价值。
To structure which may bearing dynamic loading action during design reference period,it is a important content to avoid generating resonance vibration or analogy resonance vibration phenomena The object of this paper is chemical structure which bearing dynamic′ oading action and being influened by external corrosive agents to structure autooscillatio frequence It is also analyse that durability degree attenuation regularity on the basis of frequency constraint condition when structure bearing dynamic loading serviced for some years These have certain reference value to structure design and evalution
