How to Define Steel Structure in Civil Engineering?

A structure that’s assembled from various steel members of different sizes and shapes connected with each other either by welding, Bolting or by Riveting and performs some function and safely withstands the subjected loads is called Steel Structure.

These could be the bridges, Trusses, Industrial building, sheds, cranes, silos, bunkers, tall transmission line towers, oil & gas Storage tanks, walkways, Rail over-bridges, Railways Platform, Bus stand shelters, tall residential building frames, stadium roofs or very simple and common structure like ladders, stairs, hand railing, balustrades, lampposts, bollards, flag hosting poles, electric poles and so many structure where steel structure dominates.

Steel is an alloy mostly used in Civil Engineering Construction due to its strength affordability and hardness.

Depending on physical and chemical property steel can be divided into following types

Mild Steel: it consists of Iron (98%) + Carbon (0.05-0.25%)

Stainless Steel SS: It contains less than 1.2% of carbon content and 11% Chromium to make SS.

Alloy Steel: it is a mixture of additional elements such as manganese, chromium, nickel with carbon content is (0.1% - 1% depending on type)

Steel is extremely versatile and can be molded to many different shapes. The design engineer chooses different section as per their requirement.

The main common sections which are used in steel structure are following:

I-beam, L-angle, wide flange, T-bar, HSS and Channel section.
