SIMPLE CONNECTION: RIVETED, BOLTED AND PINNED

INTRODUCTION:

The various elements of a steel structure like tension, compression & flexural member are connected by connectors (fasteners). Connection forms an important part of any structure and are designed

more conservatively than members. Connection member consists of components such as cleats, gusset plates, brackets, connecting plates and connectors such as rivets, bolts, pins and welds.
The connection provided in steel structure is can be classified as:

1.  Riveted,
2. Bolted, and
3. Welded Connection

Riveted connection were once very popular and still used in same cases but gradually be replaced b bolted connection.

Types of riveted joints:

1. Lap joint
2. Butt joint.

Lap joint:

The two members are to be connected are developed and connected together such a joint is called as lap joint.

Butt joint:

The two members are to be connected are placed end to end.

Assumption taken in rivets:

1. Rivets are assumed to be stressed equally.
2. The rivet hole is assumed to be filled completely by the rivet.
3. Friction between the plates is neglacted.
4. Stress in plate is assumed to be uniform.
5. Bending of rivet is neglected.
