EN 12512:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee CEN/TC 124 "Timber structures",the secretariat of which is held by DS.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by May 2002, and conflicting national standards shall bewithdrawn at the latest by May 2002.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,Portugal, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 12512:2002



EN 12512:2001 (E)4IntroductionDevelopments in the field of load-bearing engineered timber structures in seismic regions require thatjoints made with mechanical fasteners be tested to obtain information about their ductility, dissipation ofenergy and impairment of strength under cyclic loading.This standard lays down general principles, which should be followed in order to achieve comparability ofresults from investigations carried out in different laboratories.For different purposes two different testing procedures are considered: a general one, when thedetermination of the complete cyclic load-slip performance is required (complete procedure), and aparticular one when only the determination of the main performances at a pre-determined ductility levelis required (short procedure).SIST EN 12512:2002



EN 12512:2001 (E)51 ScopeThis European Standard specifies a test method for determining the ductility, impairment of strength andenergy dissipation properties of joints made with mechanical fasteners under cyclic loading.NOTE
This standard is written, for uniformity, in terms of direct axial loads and their effects only. The standard is,however, also appropriate to the determination of the moment resisting properties of joints.2 Normative referencesThis 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 publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publicationsapply to this European Standard only when incorporated in it by amendment or revision. For undatedreferences the latest edition of the publication referred to applies (including amendments).EN 26891, Timber structures - Joints made with mechanical fasteners - General principlesfor the determination of strength and deformation characteristics (ISO 6891:1983).3 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply:3.1cyclic loadalternative load in compression and tension3.2maximum loadmaximum joint load reached during test, Fmax, s
