Statistic analysis on fatigue load effect and equivalent stress range of steel crane structures in service is carried out. the stress range distribution in whole life is deduced by the spot measurement little sample stress - time process. meanwhile the statistic analysis on the fatigue resistance process is conducted, according to fatigue data of all kinds of structural joints in domestic and overseas, which is foundation with, establish the fatigue reliability model
2 、在大量調查的基礎上，對吊車梁所承受的疲勞荷載效應與等效等幅應力進行了統計分析，同時根據國內外有關各構造細節的疲勞資料對疲勞抗力參數進行了統計分析，為建立疲勞動態可靠性分析模式奠定基礎。 -
Due to the influence of the corrosive agents in the outer environment, the resistance and dynamic reliability of the chemical structures declined with time very fast. and it is difficult for the chemical structures that with the normal design reliability level to fulfil their structural functions. on the condition that the design service life is confirmed, the design reliability level of the chemical structures should include the corrosive environment and its effect on the structures. based on agents ' corrosiveness fuzzy classification, this paper suggests a practical method on design reliability level decision - making of the industrial structures, which is very useful for the anti - corrosion design of the industrial structures
化工結構由於受到外部腐蝕性介質環境的影響，其承載能力及動態可靠度水平隨使用時間衰減過快，按照普通結構設計可靠度水平設計的工業建築常難以順利完成設計使用功能.因此，在設計基準期預先確定條件下，化工結構的設計可靠度水平應綜合考慮腐蝕性環境及其對建築結構的影響特點來決策.根據介質腐蝕性模糊分級，提出了工業建築設計可靠度水平的一種實用決策方法
