6、Committee NA 005-51-02 AA Einwirkungen auf Bauten (Sp CEN/TC 250/SC 1) of the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee). This standard is the National Annex to DIN EN 1991-3:2010-12 Eurocode 1: Actions on structures Part 3: Actions induced by cranes and machinery.

7、 European Standard EN 1991-3 allows national safety parameters, referred to as Nationally Determined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verification methods, the provision of individual values and the selection of classes from designated classificat

8、ion systems. The relevant parts of the text are identified in the European Standard by references to the possibility of national choice and are listed in Clause NA.2.1 The National Annex is an integral part of DIN EN 1991-3:2010-12. DIN EN 1991-3:2010-12 and this National Annex DIN EN 1991-3/NA:2010

12、n into consideration when applying DIN EN 1991-3:2010-12 in Germany. NA.2 National provisions for application of DIN EN 1991-3:2010-12 NA.2.1 General DIN EN 1991-3:2010-12 refers to the option of choosing Nationally Determined Parameters (NDPs) in the following places in the text: 2.1(2) Procedure w

13、hen actions are given by the crane supplier 2.5.2.1(2) Eccentricity of wheel loads 2.5.3(2) Maximum number of cranes to be considered in the most unfavourable position 2.7.3(3) Value of friction factor A.2.2(1) Definition of -values for cases STR and GEO A.2.2(2) Definition of -values for case EQU A

14、.2.3(1) Definition of -values NA.2.2 Nationally Determined Parameters (NDPs) NOTE In the following, the clauses are numbered as in DIN EN 1991-3:2010-12. NDP re 2.1(2) Where the crane supplier is known at the time of design of the crane runway, the data he provides on the runway may be used. These s

15、hall be included in the technical documentation. NDP re 2.5.2.1(2) (1) The eccentricity e of wheel loads equals: e = 0,25 brNDP re 2.5.3(2) Table 2.3 applies. NDP re 2.7.3(3) The recommended values apply. NDP re A.2.2(1) The values given in the following Table NA.A.1 apply. DIN EN 1991-3/NA:2010-12
