9、de 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 as Nationally Determined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verif

10、ication 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 Standard by references to the possibility of national choice and are listed in Clause NA.2.1. This National Annex als

In cases where higher loads are predominant, the higher loads shall be used. cFor the transmission of loads in ceilinged rooms where there is no sufficient lateral distribution onto the supporting elements, the stated value may be reduced by 0,5 kN/

43、m2. dFor combinations of actions, the actions shall be assigned to the category of the respective building or building part. eIf the local minimum load-carrying capacity is required to be verified (e.g. for construction elements without sufficient lateral distribution of the loads), then this verifi

45、lightweight partitions may be taken into account for a wall-length related maximum load of up to 5 kN/m by adding a uniformly distributed load to the imposed load (partition allowance). This applies with the exception of walls located parallel to the beams of ceilings without sufficient lateral dist

46、ribution. For walls which, including plaster, produce a wall-length related load of up to 3 kN/m, an allowance of at least 0,8 kN/m2shall be added to the imposed load whereas for walls producing a wall-length related load of more than 3 kN/m and up to 5 kN/m, an allowance of at least 1,2 kN/m2shall

47、be added. An allowance is not required where imposed loads are 5 kN/m2 and more. Loads due to movable partitions shall be treated as imposed loads.
