What is meant by bolted connection?

What is meant by bolted connection?

Bolted joints are one of the most common elements in construction and machine design. They consist of fasteners that capture and join other parts, and are secured with the mating of screw threads. There are two main types of bolted joint designs: tension joints and shear joints.

What are the different types of bolted connections?

(b) Classification based on the type of force experienced by the bolts: The bolted connections can also be classified based on geometry and loading conditions into three types namely, shear connections, tension connections and combined shear and tension connections.

What is the advantage of bolted connection?

Advantages of Bolted Connections No special equipment/process needed for installation. Fast progress of work. Accommodates minor discrepancies in dimensions. The connection supports loads as soon as the bolts are tightened.

What is bolted connection in steel structure?

Generally, the bolts are used to connect the pieces of metals by inserting them through the holes in the metals; at the threaded end, nuts should be tightened. The advantages of bolted connections are as follows: The process of erection of structure can be made faster. Skilled labors are not necessary.

Which type of connection is single bolted connection?

In a simple connection, all bolts share the load equally. In a bolted shear connection, the bolts are subjected to shear and the connecting / connected plates are subjected to bearing stresses.

What are the advantages of staggering holes in bolted connection?

For a bolted tension member, the connecting bolts can be staggered for several reasons: 1. To get more capacity by increasing the effective net area. 2.

What is pitch in bolted connection?

Pitch of the Bolts (p): It is the centre-to-centre spacing of the bolts in a row, measured along the direction of load. 2. Gauge Distance (g): It is the distance between the two consecutive bolts of adjacent rows and is measured at right angles to the direction of load.

What is shear plane in bolted connection?

The maximum shear in the bolt occurs at the contact surface of the connected plates. The strength capacity of the bolt, then, is the shear strength of the bolt where the shear is at its maximum. The location of maximum shear in the bolt is commonly referred to as a SHEAR PLANE.

What is the advantages and disadvantages of bolted connection?

Bolted connection has very lesser strength in the axial tension as the root net area of thread is less. Under the vibratory loads, the strength is reduced if the connections are get very loosened.

What are the advantages of staggering holes in a bolted connection?

What is the minimum pitch distance of bolted connection?

6. What is the minimum pitch distance? Explanation: Pitch is centre to centre spacing of bolts in a row, measured along direction of load. Distance between centre to centre of fasteners shall not be more than 2.5 times nominal diameter of fasteners.

What is end distance in bolted connection?

End distance (e1), i.e., the distance measured in the line of force from the center of the bolt hole to the nearest edge of an adjacent hole or to the end of the plate [11], has effects on the ultimate strength and failure mode of a bolted connection subjected to tensile loading.
