1、Designation: D 5933 96 (Reapproved 2007)Standard Specification for258-in. and 4-in. Diameter Metal Shear Plates for Use inWood Constructions1This standard is issued under the fixed designation D 5933; the number immediately following the designation indicates the year oforiginal adoption or, in the

2、case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers standardizing the dimensionsand materials for the manufacture

3、 of 258 and 4-in. diametersteel or cast iron shear plates used in the fabrication ofconnections in wood constructions. The referencing of thisspecification in design, construction, and purchase order docu-ments gives the using parties ensurance that the shear plates tobe used in an assembly meet min

4、imum materials qualitystandards and that dimensions for fabrication and finish can berelied on to ensure connection performance. This specificationprovides regulatory agencies with a set of standards by whichto judge the acceptability of shear plates encountered in thefield and in fabricators shops.

5、1.2 The values stated in inch-pound units are to be regardedas standard. The values in parentheses are for information only.1.3 Safety HazardsThere are no known hazards with theuse of this specification. The products manufactured to thisspecification should not be brittle or difficult to install wit

Terminology3.1 Definition:3.1.1 shear plateA round, cast, or stamped disk-likeload-transfer device having a flat base and a perimeter bearingrim protruding in one direction normal to the base, with a holepassing through the center of the disk to accommodate anattachment bolt or

9、 lag screw.3.1.1.1 DiscussionThe fastener hole at the center mayhave an additional bearing hub. If a bearing hub is present itprojects in the same direction as the bearing rim. A shear plateis installed into one or more faces of a piece of wood to transfershear forces between the member containing t

10、he shear plate orplates and adjacent members which may be of wood or steel.This shear transfer is accomplished through the bolt or lagscrew.4. Classification4.1 This specification covers the two basic diameters ofmetal shear plates commonly used in North American timberconstruction258 in. (66.7-mm)

11、diameter stamped steel ormalleable cast iron, and 4-in. (102.1-mm) diameter malleablecast iron. The use of these shear plates is covered in theNational Design Specification for Wood Construction4andother wood design documents.5. Materials and Manufacture5.1 General:5.1.1 Cast iron shear plates shall

12、 be free from any castingdefects such as voids, irregular holes or sharp burrs greaterthan 0.03 in. (0.8 mm), or any other casting defect that wouldhinder normal installation and performance. All residual metalat casting gate locations and any other protrusions that wouldprevent the proper installat
