5、foreword This standard has been prepared by Technical Committee CEN/TC 250 “Structural Eurocodes” (Secretariat: BSI, United Kingdom). The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee), Working Committee NA 00

6、5-08-16 AA Tragwerksbemessung (Sp CEN/TC 250/SC 3). EN 1993-1-7 was approved by CEN on 12 June 2006. This European Standard is part of a series of standards dealing with structural design (Eurocodes) which are intended to be used as a “package”. In Guidance Paper L on the application and use of Euro

7、codes, issued by the EU Commission, reference is made to transitional periods for the introduction of the Eurocodes in the Member states. The transitional periods are given in the Foreword of this standard. In Germany, this standard is to be applied in conjunction with the National Annex. Attention

25、of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2007, and conflicting national standards shall be withdrawn at the latest by March 2010.

27、 following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, 1 General 1.1 Scope (1)P EN 1993-1-7 provides basic design rules for the structural design of unstiffened and stiffened plates which form part of plated structures such as silos, tanks or contain

28、ers, that are loaded by out of plane actions. It is intended to be used in conjunction with EN 1993-1-1 and the relevant application standards. (2) This document defines the design values of the resistances: the partial factor for resistances may be taken from National Annexes of the relevant applic

29、ation standards. Recommended values are given in the relevant application standards. (3) This Standard is concerned with the requirements for design against the ultimate limit state of: plastic collapse; cyclic plasticity; buckling; fatigue. (4) Overall equilibrium of the structure (sliding, uplifti

30、ng, overturning) is not included in this Standard, but is treated in EN 1993-1-1. Special considerations for specific applications may be found in the relevant applications parts of EN 1993. (5) The rules in this Standard refer to plate segments in plated structures which may be stiffened or unstiff

31、ened. These plate segments may be individual plates or parts of a plated structure. They are loaded by out of plane actions. (6) For the verification of unstiffened and stiffened plated structures loaded only by in-plane effects see EN 1993-1-5. In EN 1993-1-7 rules for the interaction between the e

32、ffects of inplane and out of plane loading are given. (7) For the design rules for cold formed members and sheeting see EN 1993-1-3. (8) The temperature range within which the rules of this Standard are allowed to be applied are defined in the relevant application parts of EN 1993. (9) The rules in

33、this Standard refer to structures constructed in compliance with the execution specification of EN 1090-2. (10) Wind loading and bulk solids flow should be treated as quasi-static actions. For fatigue, the dynamic effects must be taken into account according to EN 1993-1-9. The stress resultants ari

34、sing from the dynamic behaviour are treated in this part as quasi-static. 1.2 Normative references (1) This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publicatio

35、ns are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 1993 Eurocode

(2) The following terms and definitions are supplementary to those used in EN 1993-1-1: 1.3.1 Structural forms and geometry 1.3.1.1 Plated structure A structure that is built up from nominally flat plates which are joined together. The plates may be stiffened o

39、r unstiffened, see Figure 1.1. Plated structure Subpanels Transverse stiffener (trough or closed) Longitudinal stiffeners (open or closed) Plate segment Figure 1.1: Components of a plated structure 1.3.1.2 Plate segment A plate segment is a flat plate which may be unstiffened or stiffened. A plate s

40、egment should be regarded as an individual part of a plated structure. 1.3.1.3 Stiffener A plate or a section attached to the plate with the purpose of preventing buckling of the plate or reinforcing it against local loads. A stiffener is denoted: longitudinal if its longitudinal direction is in the

41、 main direction of load transfer of the member of which it forms a part. transverse if its longitudinal direction is perpendicular to the main direction of load transfer of the member of which it forms a part.

42、h transverse and/or longitudinal stiffeners. 1.3.1.5 Sub-panel Unstiffened plate surrounded by stiffeners or, on a web, by flanges and/or stiffeners or, on a flange, by webs and/or stiffeners. 1.3.2 Terminology 1.3.2.1 Plastic collapse A failure mode at the ultimate limit state where the structure l

43、oses its ability to resist increased loading due to the development of a plastic mechanism. 1.3.2.2 Tensile rupture A failure mode in the ultimate limit state where failure of the plate occurs due to tension. 1.3.2.3 Cyclic plasticity Where repeated yielding is caused by cycles of loading and unload

44、ing. 1.3.2.4 Buckling Where the structure looses its stability under compression and/or shear. 1.3.2.5 Fatigue Where cyclic loading causes cracking or failure. 1.3.3 Actions 1.3.3.1 Out of plane loading The load applied normal to the middle surface of a plate segment. 1.3.3.2 In-plane forces Forces

45、applied parallel to the surface of the plate segment. They are induced by in-plane effects (for example temperature and friction effects) or by global loads applied at the plated structure. 1.4 Symbols (1) In addition to those given in EN 1990 and EN 1993-1-1, the following symbols are used: (2) Mem

The shear stresses bxz and byz due to qx and qy are in most practical cases insignificant compared to the other components of stress, and therefore they may normally be disregarded for the design.
