化工结构由于受到外部腐蚀性介质环境的影响 ,其承载能力及动态可靠度水平随使用时间衰减过快 ,按照普通结构设计可靠度水平设计的工业建筑常难以顺利完成设计使用功能 .因此 ,在设计基准期预先确定条件下 ,化工结构的设计可靠度水平应综合考虑腐蚀性环境及其对建筑结构的影响特点来决策 .根据介质腐蚀性模糊分级 ,提出了工业建筑设计可靠度水平的一种实用决策方法 .
Due to the influence of the external corrosive medium environment, the chemical structure of the structure is degraded too quickly with the use of time. The industrial building designed according to the reliability level of general structural design is often difficult to successfully complete the design and use functions. Therefore, the design Under the pre-determined conditions of the reference period, the design reliability level of the chemical structure should be comprehensively taken into account in determining the corrosive environment and its impact on the building structure. According to the fuzzy classification of medium corrosivity, a practical level of reliability for industrial building design is proposed. Decision method
