Types of steel structures

In the vast landscape of construction, steel structures provide both durability and versatility. Within this resilient framework, there are various types of steel structures, each designed to meet specific architectural and engineering requirements. Let’s explore the difference between portal frames, box frames, goal post frames, cranked roof frames, and more. Take a look at distinctive characteristics that define these different types of steel structures.

Let’s delve into different steel structure types

Portal frame structures, often seen in industrial and commercial settings, feature horizontal steel beams and vertical columns. They create a rigid skeleton that efficiently supports large spans. Their simple design allows for cost-effective construction, making them adaptable to diverse applications, from warehouses to aircraft hangars.

Box frame structures epitomise structural efficiency by incorporating closed geometric shapes. The inherent symmetry of box frames, formed by connecting beams and columns to create closed sections, enhances load-bearing capacity. This design is often employed in high-rise buildings and bridges, where structural integrity meets the demand for aesthetic uniformity. Their rigid framework offers remarkable strength and stability. Moreover, these structures are highly efficient in terms of material usage. It makes them cost-effective solutions for a wide range of construction projects. Furthermore, their ease of assembly facilitates swift construction timelines, reducing overall project durations. Ultimately, portal frame structures stand as enduring symbols of innovation and practicality in the realm of modern construction.

Goal post frame structures, resembling sports goalposts, feature horizontal beams supported by vertical columns at each end. This configuration allows for open and unobstructed spaces, making goal post frames suitable for applications such as sports facilities, exhibition halls, and auditoriums. Therefore, the absence of central columns ensures maximum utility of interior space.

Cranked roof frame structures add an artistic touch to structural design by introducing angles or bends in the roof structure, creating visually striking profiles. The cranked elements not only serve an aesthetic purpose. Most importantly, they enhance the structural performance of the roof, optimising both form and function.

Space frame structures are intricate networks of linear elements forming a geometric pattern. Comprising interconnected nodes and struts, space frames distribute loads efficiently across the structure. This way, they allow for immense flexibility in creating large and lightweight structures like airport terminals and exhibition pavilions.

Truss structures showcase the elegance of simplicity. Composed of straight members connected to form triangular patterns, trusses are efficient load-bearing systems. Meanwhile, variations like Pratt trusses and Warren trusses find applications in bridges, roofs, and towers, embodying a harmonious blend of strength and structural efficiency.

Cantilever structures extend horizontally from a vertical support, creating visually striking and functionally innovative designs. Commonly used in buildings with overhanging sections or bridges with extended spans, cantilever structures highlight the dynamic capabilities of steel in defying gravity with grace. They embody architectural ingenuity and engineering prowess. These structures defy conventional building methods by extending horizontally beyond their supporting base, creating visually stunning and functionally efficient spaces. Cantilevered designs offer unparalleled flexibility in architectural expression, allowing for the creation of dramatic entrances, expansive balconies, and awe-inspiring bridges. Moreover, their innovative construction techniques often result in reduced material usage and environmental impact. Also, cantilever structures can enhance the usability of outdoor spaces, providing shaded areas or covered walkways.

Braced frame structures, characterised by diagonal braces connecting beams and columns, offer stability and resistance against lateral forces like wind or seismic activity. Commonly used in tall buildings, these structures ensure both structural integrity and safety. The diagonal bracing serves as a network that mitigates the impact of external forces. As a result, braced frame structures are very stable and rigid.

This diverse array of steel structures, from the industrial prowess of portal frames to the aesthetic allure of cranked roof frames, exemplifies the adaptability of steel in meeting the demands of modern construction. Each type brings its unique blend of form and function, shaping skylines, supporting infrastructure, and inspiring architectural marvels. So, as steel structures evolve, they will redefine the boundaries of design and engineering excellence. MAH Steel is ready to deliver on that promise.
