Steel structure:

It is the assembly of structural steel shades joined together by means of connections and the connections may be riveting or bolting.

Types of steel structures:

Here are two basic types of steel structure. I-e

1: Framework (or) Skeletal System:

In this type of structure, the main load carrying element (members) is “one dimensional” a “line element” i-e, beams, columns

For example industrial buildings, highways and railways, bridges of long time, towers, multi-storys’ of  buildings etc. 

2:Shell System:

In this type of structures, the main load carrying elements are plates and sheets besides some skeletal members.

For example tanks containing gas or liquid and bankers which are used for the storage of loose materials and all the types of large diameter steel pipes.

Types of steel structure elements with respect to building units:

There are two types.

1: rolled section

2: built up section

Rolled sections:

Structural elements which are fabricated in steel mills are called as “rolled section”.

Built-up section:

There are compositions of rolled section for in-situ use.
