We as civil engineers know that steel plays a big part of our professional lives. Steel is used in almost every building around the world. Why is that? Steel is popular and it is one of the most important materials used in constructing that is because steel has a very high tensile strength and is much cheaper than other materials with similar properties. Steel is a mixture of carbon and iron.
Steels containing 0.2% C to 1.5% C are known as carbon steel. They are of three types. It contains 14% to 18% chromium and 7% to 9% nickel.
The three types of carbon steel are :
- Low carbon steel
- Mild carbon steel
- High carbon steel
- The other types of steel are alloy steel and stainless steel.
Why use steel?
Steel is not only one of the strongest materials in the world today, it is the best automotive material in terms of its design flexibility, cost effectiveness, low emissions during manufacture, recyclability, and the list could go on. The typical strength of steel is 50 ksi which is a lot higher than other materials and it is much lighter as well.
Structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and mechanical properties. Structural steel shape, size, composition, strength, storage, etc., is regulated in most industrialized countries.
What We did in our project
We were assigned by our Instructor to design a 12 story building with certain load combinations and we were asked to design and analyze this building.
We used ETABS to do our software analysis, at first we chose the steel type and number of stories after that we continued and designed the slabs and walls.
Bracing frames must be used in the perpendicular direction and frames that resist moment must be used in one direction for lateral force resisting system.
This report contains screenshots of the work we have done in the software and also contains the manual calculations of 3 beams and 3 columns that are required to check and make sure that the values we got from ETABS are correct.
- Superimposed dead load: 2.5 kN/m2
- Live load: 3.5 kN/m2
- Cladding: choose suitable value
- Wind: Building located in Musaffah with 100 mph design wind speed
