WHAT IS STEEL STRUCTURE
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section.
COMMON STEEL STRUCTURE
Steel has high strength per unit mass, Hence, it is used for constructing large column-free structures
The following are the common steel structures in use:
1. Roof trusses for factories, cinema halls, auditoriums, ete.
2. Trussed bents, crane girders, columns, cte., in industrial structures
3. Roof trusses and columns to cover platforms in railway stations and bus stands.
4. Single layer or double layer domes for auditoniums, exhibition halls, indoor stadiums, etc
5. Plate girder and truss bridges for railways and roads
6. Transmission towers for microwave and electric power
7. Water tanks.
8. Chimneys, ete.
ADVANTAGES AND DISADVANTAGES OF STEEL STRUCTURES
The advantages of steel over other materials for construction are:
1. Steel is moderately cheap when compared with other structural materials.
2. Steel structures are highly fire-resistant when contrasted to a wooden design as wood is a combustible material and less fire-resistant when determined with RCC structure.
3. One of the advantages of using a steel structure in development is that steel's ability to span greater distances with steel ceiling joists. This enables architects to grow their choices, allowing them to make new/huge space utilizing steel items that weren't accessible with different materials.
4. Steel can be efficiently & effectively manufactured and significantly delivered. Steel structures can be provided off-site at shop floors and after that gathered nearby. This spares time and increases the efficiency of the general development process.
5. Steel structures can withstand outside weights, for example, earthquakes, thunderstorms, and cyclones. A well-fabricated steel structure can last more than 30 years whenever looked after well.
6. Flexibility is the main advantages of steel structure, which means that it tends to be planned according to the design requirements. This plots a steel structure to withstand heavy winds or earthquakes, especially in the bridges or tall towers.
7. Because of simple-to-make portions of a steel structure, it is hassle-free to install and assemble them on-site, and there is no need to estimate and cut off parts nearby.
8. Some of the common advantages of using steel buildings are Design, Strength and Durability, Light in Weight, Easy Installation and Speed in Construction, Versatile, Flexibility, Ductility, Easy Fabrication in Different Sizes, Fire Resistance, Pest, and Insect Resistant, Moisture and Weather Resistance, Adaptability, Cost-effective, Environment Friendly, Energy Efficiency, Improved Construction Quality, Temporary Structures, Safe and Resistant and Risk Index.
THE DISADVANTAGES OF STEEL OVER OTHER MATERIALS FOR CONSTRUCTION ARE :
1 Buckling is an issue with steel structures. As the length of the steel segment builds, the chances of buckling also increase.
2 Steel is available only at the steel plants where it is produced and should be transported for long distances to the construction site, not at all like concrete or different materials that might be accessible right at the site of development.
3 Due to rust in steel, costly paints are required to reestablish from time to time so that resistance against severe conditions increments.
4 Even though steel is a flexible material, it is challenging to make field corrections if one or more components do not fit appropriately. A large portion of the metal structure performs adhere to strict quality assurance procedures guarantee all pieces of a system fit accurately. But in actual it is not possible. One can't form it or cut it in the ideal shape on-site once it is fabricated.
5 Steel can't mold in any path you required. It must be utilized in structures in which areas initially exist.
6 Steel is a good conductor of heat, touches off materials in contact, and often causes fires, quickly spreading to different segments of a structure. Hence, steel structures may require extra fireproofing treatment.
REASONS WHY STEEL STRUCTURE IS THE BEST CHOICE ?
1. Cost savings
Steel structure is the cost leader for most projects in materials and design. It is inexpensive to manufacture and erection, requires less maintenance than other traditional building methods.
2. Creativity
Steel has a natural beauty that most architects can’t wait to take advantage of. Steel allows for long column-free spans and you can have a lot of natural light if you want it in any shape of structures.
3. Control and Management
Steel structures is fabricated at factory and rapidly erected at construction site by skilled personnel that makes safe construction process. Industry surveys consistently demonstrate that steel structures is the optimal solution in management.
4. Durability
It can withstand extreme forces or harsh weather conditions, such as strong winds, earthquakes, hurricanes and heavy snow. They are also unperceptive to rust and, unlike wood frames, they are not affected by termites, bugs, mildew, mold and fungi.
