Ø Any steel structure is an assemblage of different members such as beam, column and tensile members which are to be connected to one another. Connections between different members of a steel framework not only facilitate the flow of forces and moment to one member to another member but also allowed the transfer of forces up to the foundation level.
 

Classify the connection of various types.

·       Method of fastening such as rivets, bolts and welding.
·       Connection rigidity – simple, rigid and semi- rigid.
·       Joint Resistance – Bearing and friction type.
·       Fabrication location – Shop or field connection.
·       Joint location – Beam-column, Beam-Beam and Column-Foundation.
·       Connection geometry – Single-angle, double angle and I-section etc.
 

What is meant bolt of class 4.6 ?

 

Ø  The number 4 indicates 1/100_th of the ultimate tensile strength in N/mm². And number 6 indicate the ratio of yield stress to ultimate stress expressed as a percentage. Thus, the ultimate tensile strength of class 4.6 is 400 N/mm² and yield 400*0.6 = 240 N/mm².
