What are the classifications of steel structure?

Classifications of Steel Structures:

Based on Structural Behavior:

Rigid Frame Structures: Utilize rigid connections between members to resist horizontal and vertical loads efficiently.

Pin Jointed Structures: Employ pinned connections, allowing rotational movement at joints to accommodate structural deformations.

Based on Structural Form:

Truss Structures: Comprise interconnected triangular units to distribute loads effectively along the members.

Frame Structures: Consist of beams and columns interconnected to form a rigid framework supporting loads.

Arch Structures: Utilize curved elements to carry loads through compression forces.

Suspension Structures: Depend on tension cables to support the structure and transmit loads to supports.

Based on Span:

Short Span Structures: Typically used for smaller buildings like residential houses and small commercial buildings.

Medium Span Structures: Found in mid-sized structures such as warehouses and shopping complexes.

Long Span Structures: Used in large-scale constructions like airports, stadiums, and exhibition halls.

Based on Function:

Industrial Structures: Designed for manufacturing plants, warehouses, power plants, and refineries.

Commercial Structures: Cater to office buildings, shopping malls, hotels, and retail spaces.

Residential Structures: Include houses, apartments, and condominiums.

Institutional Structures: Serve educational institutions, hospitals, government buildings, and cultural centers.

Based on Structural System:

Moment-Resisting Frame System: Resists lateral loads by bending moments in beams and columns.

Braced Frame System: Utilizes diagonal bracing to resist lateral loads.

Shear Wall System: Employs vertical walls to resist lateral forces like wind and seismic loads.

Composite System: Combines steel with other materials like concrete for enhanced structural performance.

Based on Construction Method:

Conventional Steel Structures: Fabricated and erected on-site using traditional methods.

Pre-engineered Steel Buildings: Utilize standardized components manufactured off-site and assembled quickly at the construction site.

Understanding these classifications helps in the design, analysis, and construction of steel structures tailored to specific requirements, ensuring optimal performance and functionality in various applications.
