![]() ![]() In lap joints the components to be joined overlap each other, while for butt joints an additional piece of material is used to bridge the two components to be joined which are butted up against each other. The available length of the gusset plate for making connection is 250 mm. There are two main types of riveted joint: lap-joints and butt-joints(Fig.4). 809.8MPa for FA-100 bolt, and 789.6 for FA-100 coupon). A tension member carrying a factored tensile load of 180 KN has to convert through a gusset plate of 10 mm thick using 16 mm diameter of ordinary bolt of grade 4.6. The rivet is driven into the target materials with high force, piercing the top sheets and spreading outwards into the bottom sheet of material under the influence of an upsetting die to form the joint.įactors in the design and specification of rivets include the size, type and material for the rivet, the type of joint, and the spacing between rivets. ![]() An example of the application of a closed end blind rivetĪ further type of rivet with potentially many over-all advantages, from the production perspective, is the self-piercing rivet that does not require a predrilled hole. The advantage of blind rivets (Fig.3) is that they require access to only one side of the joint.įig 3. The two main types of rivet are tubular and blind and each type are available in amultitude of varieties. Most of DIN 674 Steel Rivets are made of steel. In the article authors presented numerical and experimental investigation of bolted connections with blind rivet nuts. In general a given size rivet will be not as strong as the equivalent threaded fastener. DIN 674 Steel Rivets act as a releasable connection or fastening element for all types of components. Care needs to be taken in the selection of material and coating to avoid the possibility of corrosion by galvanic action. A variety of coatings are available to improve corrosion resistance. Rivets can be made from any ductile material such as carbon steel, aluminium and brass. Two historical examples of the use of rivets on the Lockheed Electra and RB211engine nacelle. Rivets tend to be much cheaper to install than bolts and the process can be readily automated with single riveting machines capable of installing thousands of rivets an hour.įig 2. You can calculate the shear strength or the tensile. Allowable stresses: Tensile stresses on gross area of the plate 0.60 F y. Bolt spacing are as follows S1 40 mm, S2 80mm, S3 100. see Fig.2) boilers, ships and boxes and other enclosures. In most bolted connection, the bolts are subjected to shear. Sample Problem 5: Two plates each with thickness t 16 mm are bolted together with 622 mm bolts. Can be placed in thin sheet metal or a blind hole.
