【適用范圍】在含裂紋鋼結(jié)構(gòu)的斷裂檢測(cè)中一般假設(shè)斷裂韌度試樣的杭斷能力與構(gòu)件抗斷能力是相等的但這種假設(shè)往往導(dǎo)致過于保守的斷裂檢測(cè)結(jié)果。這是由于構(gòu)件在主要受拉伸荷載作用時(shí) 裂紋尖端附近區(qū)域出現(xiàn)塑性拘束損失所致相比之下斷裂韌度試樣由于承受彎曲荷載作用條件而在裂紋尖端附近區(qū)域產(chǎn)生很高的多軸拘束應(yīng)力狀態(tài)。最近幾年來廣泛應(yīng)用于工程結(jié)構(gòu)中的高強(qiáng)度鋼因其屈強(qiáng)比較高(屈服強(qiáng)度/抗拉強(qiáng)度)而表現(xiàn)出構(gòu)件裂紋尖端的拘束損失十分顯著斷裂檢測(cè)中迫切地需要進(jìn)行修正。本標(biāo)準(zhǔn)規(guī)定了一種方法通過考慮拘束損失將通過試驗(yàn)試樣得到的CTOD(裂紋尖端張開位移)斷裂韌度轉(zhuǎn)化為構(gòu)件等效CTOD。這種方法適用于使用應(yīng)力強(qiáng)度因子和J積分概念所進(jìn)行的斷裂韌度檢測(cè)。本標(biāo)準(zhǔn)適用于由裂紋類缺陷或鐵素體結(jié)構(gòu)鋼疲勞裂紋所引發(fā)的失穩(wěn)斷裂失穩(wěn)斷裂前出現(xiàn)明顯的延性裂紋擴(kuò)展情況不包括在本標(biāo)準(zhǔn)的適用范圍之內(nèi)。結(jié)構(gòu)鋼CTOD斷裂韌度按照ISO 12135-2002 BS 7448-1-1991或ASTM E1290-1999中任何一個(gè)規(guī)范中所規(guī)定的相應(yīng)程序進(jìn)行測(cè)試。含裂紋構(gòu)件的斷裂檢測(cè)通常使用一種相關(guān)機(jī)構(gòu)認(rèn)可的方法進(jìn)行如FAD(失效評(píng)定圖) 相關(guān)細(xì)節(jié)本標(biāo)準(zhǔn)沒有提及。本標(biāo)準(zhǔn)可用于消除過度保守觀念這種保守觀念與傳統(tǒng)斷裂力學(xué)方法有著密切聯(lián)系。既可以通過結(jié)構(gòu)鋼斷裂韌度精確地檢測(cè)構(gòu)件失穩(wěn)斷裂的初始界限，也可用于合理地確定材料斷裂韌度臨界值（驗(yàn)收值），以滿足有關(guān)鋼構(gòu)件對(duì)材料成型性能方面的設(shè)計(jì)要求。

【適用范圍】This part of ISO 834 specifies a method for testing fire protection systems applied to structural steel members used in buildings as beams columns or tension members. This part of ISO 834 is intended for use in conjunction with the assessment protocol described in ISO 834-11. It applies to steel sections (including hollow sections) and only considers sections without openings in the web. Results from analysis of I or H sections are directly applicable to angles channels and T-sections for the same section factor whether used as individual members e.g. bracing or part of a fabricated structural system such as a steel truss construction. This part of ISO 834 does not apply to solid bar rod or concrete-filled hollow sections. This part of ISO 834 describes the fire test procedures that specify the tests which should be carried out to determine the ability of the fire protection system to remain sufficiently coherent and in position for a well-defined range of deformations furnace and steel temperatures such that the efficacy of the fire protection system is not significantly impaired and to provide data on the thermal characteristics of the fire protection system when exposed to the standard temperature/time curve specified in ISO 834-1. In special circumstances where specified in National Building Regulations there can be a requirement to subject reactive fire protection materials to a smouldering curve. The test and the requirements for its use are described in Annex G. This part of ISO 834 is applicable to both passive and reactive fire protection systems as defined in the terms and definitions which are installed or applied in such a way that they remain in place for the intended duration of fire exposure. The fire test methodology makes provision for the collection and presentation of data which is then used as direct input into ISO 834-11 to determine the limits of direct application to steel sections of various shapes sizes and fire resistance periods

【適用范圍】1 ISO 12944 deals with the corrosion protection of steel structures by protective paint systems.n2 ISO 12944 covers only the corrosion-protective function of paint systems. Other protective functions like the protection against:n— microorganisms (marine fouling bacteria fungi etc.) n— chemicals (acids alkalis organic solvents gases n— mechanical action (abrasion etc.) andn— firenare not covered by ISO 12944.n3 The field of application is characterized by:n— the type of structure n— the type of surface and surface preparation n— the type of environment n— the type of protective paint system n— the type of work andn— the durability of the protective paint system.nAlthough ISO 12944 does not cover all types of structure surface and surface preparation it may by agreement also be applied to those cases which are not covered by the standard.nThe various aspects of the field of application are described in more detail in 1.3.1 to 1.3.6.n3.1 Type of structurenISO 12944 concerns structures made of carbon or low-alloy steel (e.g. in accordance with EN 10025) of not less than 3 mm thickness which are designed using an approved strength calculation.nNot covered by ISO 12944 are concrete structures reinforced with steel.n3.2 Type of surface and surface preparationnISO 12944 deals with the following types of surface consisting of carbon or low-alloy steel and their preparation:n— uncoated surfaces;n— surfaces thermally sprayed with zinc aluminium or their alloys;n— hot-dip-galvanized surfaces;n— zinc-electroplated surfaces;n— sherardized surfaces;n— surfaces painted with prefabrication primer;n— other painted surfaces.n3.3 Type of environmentnISO 12944 deals with:n— six corrosivity categories for atmospheric environments n— three categories for structures immersed in water or buried in soil.n3.4 Type of protective paint systemnISO 12944 covers a range of paint products which dry or cure at ambient conditions. Not covered by ISO 12944 are:n— powder coating materials n— stoving enamels n— heat-cured paints n— coatings of more than 2 mm dry-film thickness n— linings of tanks n— products for the chemical treatment of surfaces (e.g. phosphating solutions).n3.5 Type of worknISO 12944 covers both new work and maintenance.n3.6 Durability of the protective paint systemnISO 12944 considers three different durability ranges (low medium and high). See 3.5 and clause 4.nThe durability range is not a "guarantee time".
