6、usschuss Bauwesen (Building and Civil Engineering Standards Committee). This document is the National Annex to DIN EN 1998-1:2010-12 Eurocode 8: Design of structures for earthquake resistance Part 1: General rules, seismic actions and rules for buildings. European Standard EN 1998-1 allows national

7、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 classification systems. The relevant parts of the text a

8、re identified in the European Standard by references to the possibility of national choice and are listed in Clause NA.2.1. This National Annex also includes non-contradictory complementary information (NCI) for the application of DIN EN 1998-1:2010-12. This National Annex is an integral part of DIN

42、4) General If there is insufficient information regarding the ground, ground type C as defined in 3.1.2(1) may be assumed without carrying out a separate ground investigation unless the special case described in 3.1.2(1) applies. If it does, the influence of local ground conditions on the seismic ac

43、tion shall be analysed and taken into account separately. NCI re 3.1.1 General (NA.5) The influence of local ground conditions on the seismic action shall generally be taken into account by determining which of the three geological ground types, R, T or S (see 3.1.3), and which of the three ground t

44、ypes, A, B or C (see 3.1.2), exist at the respective site. (NA.6) The following combinations of ground type and geological ground type are possible: A-R, B-R, C-R, B-T, C-T or C-S. NDP re 3.1.2(1) Identification of ground types (i) In Germany, a distinction is made between the following ground types

45、: Ground type A Unweathered solid rock of high strength. The dominant shear wave velocities exceed 800 m/s. Ground type B Solid rock with average weathering and solid rock with low strength or coarse-grained (gravels) or composite soils with high friction properties, of dense compaction or solid con

46、sistency (e.g. glacially compacted soils). The dominant shear-wave velocities are roughly within the range of 350 m/s to 800 m/s. Ground type C Considerably eroded or completely eroded solid rock or coarse-grained (gravels) or mixed-grain soils of medium compaction or a relatively solid consistency

47、or fine-grained (cohesive) soils of a relatively stiff consistency. The dominant shear wave velocities are roughly within the range of 150 m/s to 350 m/s. DIN EN 1998-1/NA:2011-01 8 (ii) If it is not possible to classify the ground according to paragraph (i), particularly if deep-reaching uncompacte

48、d loose deposits (e.g. loose sand) or soil of soft or semi-fluid consistency (e.g. lacustrine clay, silt) are present (dominant shear wave velocities are lower than 150 m/s), then the influence of the ground conditions on seismic activity shall be analysed and taken into consideration separately. (iii) The site of a structure should normally be free from any risk of slope instability or permanent settlement due to liquefaction in the event of an earthquake.
