32、uction 0.1 Effects of seismic actions on racking systems Racking systems are load bearing structures for the storage and retrieval of goods in warehouses. The goods are generally stored on pallets or in box containers. Racking systems are constructed from steel components; although components are st
33、andardized, they are only standard to each manufacturer. These components differ from traditional steel components in the following regard: a) continuous perforated uprights; b) hook-in connections; c) structural components for racking, which generally consist of cold formed thin gauge members. In r
34、espect of the loads, the self-weight of a rack structure is typically very small or negligible with respect to the total mass, whereas in a typical building the percentage of dead and permanent loads will be much greater. The nature and the distribution of the goods stored on racking systems strongl
35、y affect the response and the safety of the structure under seismic actions. In fact: unit loads are in general simply supported vertically by the racking structure and kept in their position when loaded by inertial actions only by friction; unit loads are in general sub-structures with distinct dyn
36、amic characteristics in terms of frequency and damping, and their behaviour affect the response of the system. During real earthquakes or earthquake simulated on shaking tables, movements of pallets on pallet beams were observed; these were either very small ones, contributing to the dissipation of
37、energy by means of friction, or very large, with movements of the pallets that produced their falling between beams or outside the rack in the aisle. For this reason, friction between pallet and pallet beam and internal damping in the unit load has a relevant influence in the dynamic response of the
38、 rack and affects the entity of the inertial actions. Also, the safety of the installation related to the movement and eventual falling of the pallets requires a proper assessment. This European Standard deals with all the relevant and specific seismic design issues for racking systems, based on the
39、 criteria of EN 1998-1:2004, Eurocode 8. 0.2 Requirements for EN Standards for racking and shelving in addition to Eurocodes While the basic technical description of an earthquake is the same for all structures, the general principles and technical requirements applicable for conventional steel stru
40、ctures have to be adapted for racking systems, in order to take into account the peculiarities of racking to achieve the requested safety level. Also, the methods of analysis and the design requirements need to be addressed to the peculiarity of racking structures. The scope of CEN/TC 344 is to esta
41、blish European Standards providing guidance for the specification, design methods, accuracy of build and guidance for the user on the safe use of steel static storage systems. DIN EN 16681:2016-12 EN 16681:2016 (E) 7 This, together with the need of harmonized design rules was the reason that Europea
42、n Racking Federation ERF/FEM Racking and Shelving has taken the initiative for CEN/TC 344. CEN/TC 344 is in the course of preparation of a number of European Standards for specific types of racking and shelving and particular applications, which exist in the European Standards (EN) and working group
43、 activities (WG). 0.3 Liaison CEN/TC 344 “Steel Static Storage Systems” liaise with CEN/TC 250 “Structural Eurocodes”, CEN/TC 135 “Execution of steel structures and aluminium structures” and CEN/TC 149 “Power operated warehouse equipment”. 0.4 Additional information specific to EN 16681 This Europea
44、n Standard is intended to be used with EN 1998-1, EN 15512 and related standards. EN 1998-1 is the first of 6 parts; it gives design rules intended to be used for structures fabricated with conventional materials, including steel. EN 15512 is the reference standard for the design of racking structur
45、es and components; it addresses the principles of the EN 1990, Eurocode, and EN 1993 series, Eurocode 3, to the adjustable pallet racking systems and it needs to be applied also when actions are produced by an earthquake. DIN EN 16681:2016-12 EN 16681:2016 (E) 8 1 Scope This European Standard specif
46、ies the structural design requirements applicable to all types of adjustable pallet racking systems fabricated from steel members, intended for storage of unit loads and subject to seismic actions. This European Standard gives also guidelines for the design of clad rack buildings in seismic zones, w
47、here requirements are not covered in the EN 1998 series. This European Standard does not cover other generic types of storage structures. Specifically, this European Standard does not apply to mobile storage systems, drive-in, drive-through and cantilever racks or static steel shelving systems. This
48、 European Standard does not apply to the design of seismic isolated racking structures. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
