What is the number of shear planes in the ordinary bolt problem of steel structures?
Double shear: when connecting three plates, the middle plate acts on the two shear planes of the bolt.
In the single shear bolted two plates are only single contact plates between both rods subjected to tension or compression, for only a bolt shear surface; connecting three plates, the middle panel for the bolt is two shear surface. For calculating the shear resistance of bolts, the standard shear strength values are different.
Steel bolt is a kind of high strength bolt, and it is also a kind of standard component. Fastening performance is better, used for steel structure, engineering, so that the role of fastening. The general steel structure, steel structure bolt requirements are more than 8.8, and level 10.9, level 12.9, all steel structure high strength bolts, sometimes bolt on steel structure is not required for electroplating, the use of color OK.
Single shear: is common in bolted connection of two plates, only one side contact between panels, regardless of rod tension or pressure, the bolt is only a shear surface.
