Shear (and tension) loads can be transferred between two structural elements by either a bearing-type connection or a slip-critical connection. In a slip-critical connection, loads are transferred from one element to another through friction forces developed between the faying surfaces of the connection. These friction forces are generated by ...
The Research Council on Structural Connections (RCSC) is a research organization focused on bolted structural connections. Their technical standard on this subject is cited in the US steel design code. [1] Prior to 1980, the organization was known as the Research Council on Riveted and Bolted Structural Joints (RCRBSJ).
Bolt banging occurs in buildings when bolted joints slip into "bearing under load", thus causing a loud and potentially frightening noise resembling a rifle shot that is not, however, of structural significance and does not pose any threat to occupants. A bolted joint between two elements may act as a bearing-type joint, or a friction joint.
A bolted joint is a mechanical joint which is the most popular choice for connecting two members together. It is easy to design and easy to procure parts for, making it a very popular design choice for many applications. Advantage: Joints are easily assembled/ disassembled by using a torque wrench or other fastener tooling. [7]
The American Institute of Steel Construction 13th Edition Steel Design Manual section 16.1 chapter J-3 specifies the requirements for bolted structural connections. [9] Structural bolts replaced rivets due to the decreasing cost and increasing strength of structural bolts in the 20th century.
DTIs within the RCSC specification section 8.2.4 are described thus: "ASTM F959 direct tension indicators are recognized in this Specification as a bolt-tension-indicating device. Direct tension indicators are hardened washer shaped devices incorporating small arch-like protrusions on the bearing surface that are designed to deform in a ...
An improvement over fishplate rail connectors is directly bonding rails together using thermite or flash butt welding. In 1967, the Hither Green rail crash occurred on the Southern Region of British Railways when a rail fractured at its fishplate joint. The crash accelerated welded rail connections, with strict procedures on concrete and wooden ...
In such connections one of the two components acts as male and the other as female, although more complex relationships exist. [1] Any electrical connector, bolted joint, and jigsaw puzzle is an example of assembling based on mating connection.
