20、to structural bearings, whether used in bridges or in other structures. This European Standard does not cover: a) bearings that transmit moments as a primary function; b) bearings that resist uplift; c) bearings for moving bridges; d) concrete hinges; e) seismic devices. Although it is not intended
21、to regulate temporary bearings this standard may be used as a guide in this case (temporary bearing are bearings used during construction or repair and maintenance of structures). NOTE 1 : Although the specifications given in this European Standard are necessary, they are not sufficient in themselve
22、s for the overall design of the structures and for the consideration of geotechnical aspects. See prEN 1337-2 to prEN 1337-8 for information relating to bearings for which specifications are laid down for certain ranges d temperature only. 2 Normative references This European Standard incorporates b

They apply here in the same way.
29、3.1.1 bearings: Bearings are elements allowing rotation between two members of a structure and transmitting the loads defined in the relevant requirements as well as preventing displacements (fixed bearings), allowing displacements in only one direction (guided bearings) or in all directions of a pl
30、ane (free bearings) as required. The most common types of bearings are listed in table 1 and examples of these are are illustrated in figure 1 with the corresponding axes of coordinates. A distinction is made between the following categories: Category 1: All-round rotating bearings Category 2: Beari
31、ngs with uniaxial rotation Category 3: Spherical and cylindrical bearings when the horizontal load is supported by the curved sliding surface Category 4: All other bearings The bearings of Nos 1.1 to 3.1, 3.3,3.5 to 4.3, 8.1 and 8.2 belong to category 1. The bearings of Nos 5.1 to 6.2,7.3 and 7.4 be
32、long to category 2. The bearings ofNos 3.2,3.4,7.1 and 7.2 belong to category 3. sTD.BSI BS EN L337-1-ENGL 2000 1111 Lb24bb9 087614b OST m e 8 P % I o z * X * z u u E O E c! m x Ix X x Ix X STD.BSI ES EN 1337-L-ENGL 2000 I LbS4bb9 083bL48 922 IC I I I I- M : m c .- H: U +-+ e w c!

41、e 17 EN 1337-1 12000 4 General principles Bearings and supports shall be designed so that bearings or parts of bearings can be inspected, maintained and replaced if necessary, in order to enable them to fulfil their function throughout the intended life of the structure. Bearings shall be designed t
42、o permit the specified movement with the minimum possible reacting force. Presetting shall be avoided as far as possible. If necessary the required presetting shall be carried out at the factory. If readjust- ment on site cannot be avoided it shall be carried out oniy by the manufacturer of the bear
43、ing or under his supervision. 5 Design principles 5.1 General The design of the various bearings shall be based on servicability andor ultimate limit state depending on the safety classification of the limit state in consideration. Where characteristic values and partial safety factors for loads and
44、 movements are not covered, either by this European Standard or an Eurocode, the designer shall determine his own values in accordance with the principles set out in ENV 1991-1 and in ENV 1992-2, ENV 1993-2 or ENV 1994-2. NOTE A special informative Annex B in ENV 1993-2 deals with bearings. 5.2 Safe
45、ty against sliding in joints Where the position of a bearing or part of a bearing is maintained completely or partially by friction its safety against slidng shall be checked at the ultimate limit state in accordance with the following: Sd R where Sd is the design shear force resulting from the acti
46、ons VRd = A * Nsd + Vpd is the design value of shear resistance y, with NSd minimum design force acting normal to the joint in conjunction with v$d ; design strength of any fixing device in accordance with European standards or European technical approvals; characteristic value of the fiction coeffi
47、cient ,uk = 0,4 for steel on steel ,Uk = 0,6 for steel on concrete partial safety factor for friction y, = 2,O for steel on steel y, = i ,2 for steel on concrete The above-mentioned values of and y, shall be used provided that prior to installation or assembly the surfaces of steel components are un
48、-coated and free from grease or metal-sprayed or coated with fully hardened zinc silicate provided that any coating has completely hardened prior to installation or assembly of the components. In other cases the values for h and y, shall be established from the results of tests. In the case of dynam
49、ically stressed structures where extreme load fluctuations can occur, e. g. railway bridges and earthquake$ the horizontal forces shall not be resisted by friction. In these cases shall be taken as zero. Safety against sliding in joints formed by elastomeric bearings without positive means of location shall be checked in accordance with prEN 1337- 3. 5.3 Conditions of installation See EN 1337- 11. Any particular conditions of installation shall be agreed between the purchaser and the manufacturer and shall be confirmed
