Lalit Mahato List the advantages and disadvantages of steel structures?
Explanation
Advantages of steel structures
1. High strength resulting in the reduction of dead weight.
2. Speedy construction is possible in the case of steel structures, where as R.C. structures can be constructed only stage by stage
3. Dismantling and reuse of steel structures will be possible where as it not possible in the case of R.C. structures.
4. They are more economical that concrete structures for tall buildings.
5. The properties of steel do not change appreciably with time .
6. Steel members occupy less space than R.C. members.
7. They are gas and water tight due to high density of steel.
8. Steel is a ductile material.
Disadvantages of steel structures
1. They are susceptibility to corrosion.
2. They losses its strength at high temperature.
3. Steel members are costly.
4. Steel elements can not be made to any desired size or shape as in the case of R.C. elements.
5. They required skilled labour for erection.
6. It required electricity for fabrication and erection of members.
7. They are susceptibility to buckling, fatigue fracture and brittle fracture.
