What is a Rigid Frame Structure?
Rigid frame structures are sometimes referred to as flexural frames. They usually consist of beams and columns held together by rigid joints. This type of frame structure can withstand both vertical and horizontal loads. In addition, because rigid frame structures have permanent connections, they can withstand shear stresses and bending moments.
Rigid frame structures are different from simple frame designs. In a simple frame design, the frame structure is allowed to rotate. As a result, rigid frame structures are very strong and can withstand heavy loads and lateral pressures (such as wind and earthquakes). The John Hancock Center in Chicago is a famous example of a rigid frame structure building. Rigid frame buildings are the most common and durable type of steel building.
Characteristics of Rigid Frame Structures
There are many unique features of rigid frame structure design, such as:
- Continuous Members: As mentioned earlier, rigid frame structures consist of continuous members such as beams and columns. They eliminate weak points in different parts of the structure.
- Rigid Connections: The connections between members are fixed, which makes it easy to spread the loads and forces across the structure. It can withstand axial loads, shear loads, and bending moments.
- Stability: Rigid frames are known for their excellent stability. This means that buildings can withstand lateral loads such as wind and earthquakes. They make buildings strong and durable, even in bad weather.
- Spans: If you want to build a building with a lot of open space and no support in the center. Then, rigid structural frames are the best choice. In addition, you have complete control over the style and layout of your house.

The Engineering Behind Rigid Frame Structures
At the heart of a rigid frame structure is a strong engineered frame. It provides superior stability and load-bearing capacity. This is achieved through a combination of advanced design principles and carefully engineered features.
Load Distribution Mechanics
Rigid connections in these frames distribute loads efficiently. This enables them to withstand large loads and resist lateral forces. This is critical in areas prone to strong winds or earthquakes. Key factors include fixed moment connections between columns and rafters, and strategic placement of corner supports. Also included is the role of bulkheads in roof and wall systems.
- Fixed-moment connections create frame action that resists lateral displacement.
- Knee braces enhance the frame’s rigidity while optimizing material usage.
- Diaphragm action distributes horizontal forces across multiple frames.
Structural Stability Features
Several engineered features work together to create a resilient building system. This includes base plate connections designed with precise anchor bolt patterns and burial depths. This ensures that the frames are securely anchored even under extreme conditions. Xinguangzheng Group’s engineering team incorporates these advanced stability features into every rigid frame design.
- Base plate connections ensure secure anchorage to foundations.
- Advanced stability features enhance performance in high winds or seismic activity.
- Inherent resistance to progressive collapse represents a significant safety advantage.
Types of Rigid Frame Structures
Rigid frame structures come in various designs to suit different building needs. The choice of design depends on the intended use, architectural style, and environmental conditions.
- Peaked Roof Designs: The peaked roof design is a popular choice for rigid frame construction. It offers excellent snow protection and more interior space. These designs are particularly suitable for buildings in areas with heavy snowfall.
- Single Slope Roof Structures: Single slope roof structures provide a modern aesthetic and can be more cost-effective. They are ideal for applications where water runoff needs to be managed efficiently.
- Custom Rigid Frame Solutions: Custom rigid frame solutions cater to unique architectural requirements or specialized functional needs. Our custom steel buildings can accommodate complex geometries, multi-level mezzanine integrations, and specialized equipment supports.
Advantages of Rigid Frame Construction
Now, we know what rigid frame construction is. Next, let’s learn about its advantages:
Better Structural Stability: The rigid connections in these frames make the structure very stable and can withstand large loads and lateral forces. This works well in places where earthquakes and strong winds are likely to occur. For this reason, many people use steel-framed structures as hurricane-proof buildings.
Stronger and More Durable: Rigid frame construction buildings can withstand harsh weather and normal wear and tear. It does not cause any major damage such as cracking of the building. In addition, a rigid frame structure can effectively distribute the weight of the entire structure. This reduces the likelihood of failure and ensures the longevity of the building. As a result, metal buildings with rigid frame construction can last for many years.
Effective Utilization of Space: Rigid frame structures are designed to maximize the use of space per square foot, which results in optimum utilization of space. It improves operational efficiency and increases productivity. Flexibility is at the heart of rigid framing. You can plan specific layouts or open floor space to expand the usable area.
Cost Effectiveness: Rigid frame structures are less expensive to build compared to other frame types. They require minimal internal bracing or supports and no costly secondary materials.
Design Flexibility: Since rigid frame structures are very strong and stable. Therefore, structural engineers can design clear-span buildings with large development spaces. Such buildings do not require internal bracing columns and are ideal for commercial and industrial buildings.
Disadvantages of Rigid Frame Structures
Although rigid frame construction has its advantages, it also has some disadvantages. Its disadvantages usually include the following:
Complexity: Designing and building rigid frame structures can be more difficult than other types of frames. They require more precise planning and calculations. This is because of the complexity of the way components such as columns and beams are connected to each other.
Settlement Sensitivity: Every settlement of the foundation can cause varying degrees of damage to rigid frame structures. In addition, settlement can cause damage by placing unconstrained stresses on the building.
Limited Flexibility: It is difficult to make changes as the connections between members are rigid. It may be difficult to change or extend the structure in the future.
Rigid Frame vs. Other Building Systems
Comparing rigid frame structures to other building systems reveals significant differences in design flexibility, strength, and construction efficiency. Rigid frames are distinct from other structural systems, such as braced frames and load-bearing structures, in their ability to provide large, unobstructed spaces.
Comparison with Braced Frame Structures: Braced frame structures rely on diagonal bracing to resist lateral loads. Rigid frames achieve stability through their connections. This difference gives rigid frames an edge in terms of design flexibility. Because they can accommodate larger openings and more varied architectural designs.
Advantages Over Load-Bearing Structures: Rigid frame structures offer several advantages over load-bearing systems. These include the ability to create expansive interior spaces without the need for supporting walls. This separation of structural and enclosure functions allows for greater flexibility in both initial design and future modifications. As a result, this makes rigid frames ideal for modern, large-scale applications such as warehouses and industrial complexes.
