6、g and Civil Engineering). This document contains amendments to the National Annex to DIN EN 1991-1-1:2010-12, Eurocode 1: Actions on structures Part 1-1: General actions Densities, self-weight, imposed loads for buildings. European Standard EN 1991-1-1 allows national safety parameters, referred to
7、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 classification systems. The relevant parts of the text are identified in the European S
8、tandard by references to the possibility of national choice and are listed in Clause NA.2.1. This Amendment to the National Annex is an integral part of DIN EN 1991-1-1:2010-12. DIN EN 1991-1-1/NA/A1:2015-05 3 1 Amendment to NDP re 6.3.3.2 (1), Table 6.8 Replace Table 6.8DE by the following table: C

10、verification of local stresses (e.g. lateral force at the support or punching shear under a wheel load). For Qkthe load model given in Figure 6.2 shall be assumed, but using a square of side lengths a = 200 mm. bIf the influence area AEF(in m2) is able to be unequivocally determined in structural sy

13、e intended to be driven upon by vehicles, the loads of bridge classes (16/16 to 30/30) as given in DIN 1072 apply. 3 Amendment to NCI re 6.3.4.2, Table 6.11 Add the following paragraph at the end: If the structural circumstances are such that roof surfaces of category K for helicopters are not able
14、to be driven upon by any type of vehicle, for transmission of the evenly distributed imposed load to roof elements supporting these roofs the imposed load may be reduced from 5 kN/m2to 3 kN/m2. 4 Amendment to NCI re Annex NA.A, Table NA.A.13 In Table NA.A.13 “Density of masonry with general-purpose,
