The Best 6 Types of Structures in Construction in Civil Engineering

Structures are the backbone of our built environment, providing support and functionality to buildings, bridges, and other infrastructure. Understanding the different types of structures is essential for architects, engineers, and construction professionals.

Types of Structures in Construction

In construction, understanding different types of structures are essential for ensuring a project’s safety, durability and efficiency. A structure is defined as a system that is designed to support loads and resist forces. There are various structures, including trusses, arches, domes, beams and frames, each with unique characteristics and applications.

Here’s a breakdown of some common structural types:

1. Framed structures

These are common in civil and building engineering and can collapse globally if local damage spreads.

Framed structures are a fundamental component of modern construction, providing stability, support, and strength to buildings and other structures. These structures are composed of interconnected elements, such as beams, columns, and slabs, that form a framework capable of resisting external loads.

Types of Framed Structures

There are several types of framed structures, each with its unique characteristics and applications:

• Steel Frame Structures: These structures are constructed using steel beams, columns, and trusses. They offer high strength, durability, and versatility, making them suitable for a wide range of building types, including skyscrapers, commercial buildings, and industrial facilities.
• Concrete Frame Structures: Reinforced concrete is used to create beams, columns, and slabs for these structures. Concrete frames are known for their fire resistance, durability, and ability to withstand heavy loads. They are commonly used in high-rise buildings, bridges, and parking garages.
• Timber Frame Structures: Wooden beams, posts, and trusses are used to construct timber frame structures. This type of construction is often used in residential and commercial buildings, especially in regions with abundant timber resources. Timber frames offer a warm, natural aesthetic and can be customized to suit various architectural styles.
• Hybrid Frame Structures: These structures combine elements from different materials, such as steel and concrete or timber and steel. Hybrid frames can offer the advantages of both materials, such as strength, durability, and aesthetics.

Advantages of Framed Structures

Framed structures offer several advantages over other types of construction:

• Flexibility: They can be easily adapted to various shapes and sizes, allowing for creative architectural designs.
• Efficiency: Framed structures can be constructed quickly and efficiently, reducing construction time and costs.
• Strength: They are designed to withstand heavy loads and seismic activity, ensuring structural integrity.
• Versatility: Framed structures can be used in a wide range of building applications, from small residential homes to large commercial complexes.

In conclusion, framed structures play a vital role in modern construction, providing a stable and durable framework for buildings and other structures. The choice of frame material depends on factors such as the building’s size, function, and desired aesthetic. By understanding the different types of framed structures and their advantages, architects and engineers can select the most appropriate solution for their projects.

2. Load-bearing structures

These structures are good for low-rise buildings, especially residences, and work well when there aren’t space constraints.

Load-bearing structures are the backbone of many buildings, providing essential support and stability. These structures rely on their own weight and the materials they support to resist external loads, such as the weight of roofs, floors, and walls.

Columns

These vertical structural elements transfer loads parallel to the longitudinal axis as compression or tension. They are used to support floor and roof beams.

Beam and column systems

This system is often used in high-rise apartment buildings and consists of vertical columns that support horizontal beams. The beams then support the weight of the floors and roof.
