Part 10: Model Construction Specification 10 - 18 With reference to Annex A1.4 of EN 1990, limits for vertical deflections according to Figure A1.1, for horizontal deflections according to Figure A1.2 and for vibrations of structures on which the public can walk, shall be specified in the contract documents and agreed with the Client. 5.2 Supplementary rules for sheeting – EN 1993-1-3 EN 1993-1-3 gives, among other, design requirements for profiled steel sheeting. Methods are also given, in this part of Eurocode 3, for stressed-skin design using steel sheeting as a structural diaphragm. National choice is allowed through clauses listed in the Foreword to EN 1993-1-3. Additional contract document requirements According to § 2(6) of EN 1993-1-3, contract documents shall define the Structural Class (I to III) of the construction, associated with failure consequences according to Annex B of EN 1990:  Structural Class I: construction where sheeting is designed to contribute to the overall strength and stability of a structure  Structural Class II: construction where sheeting is designed to contribute to the strength and stability of individual structural elements  Structural Class III: construction where sheeting is used as an element that only transfers loads to the structure. 5.3 Design of plated structural elements – EN 1993-1-5 EN 1993-1-5 gives design requirements of stiffened and unstiffened plates which are subject to in-plane forces. National choice is allowed through clauses listed in the Foreword to EN 1993-1-5. 5.4 Design of joints – EN 1993-1-8 EN 1993-1-8 gives design methods for the design of joints subject to predominantly static loading using steel grades S235, S275, S355 and S460. National choice is allowed through clauses listed in the Foreword to EN 1993-1-8. Additional contract document requirements According to § 3.4.1 of EN 1993-1-8, the category of bolted connections (Category A, B or C for joints loaded in shear, and Category D or E for joints loaded in tension) shall be specified in the contract documents.
