Rigid Frames

Rigid frame structures, also called hollow metal steel frames, offer a rotational stability that enhances how buildings carry their vertical loads, which increases the longevity of the entire structure. 

These structures share a similarity of a post and beam system, however the differences are quite notable. The main difference is the ability to hold vertical loads, without additional bracing.

Defining Rigid Frame Structures

In this type of frame, the beam to column connections are classified as rigid, hence where the name comes from. This frame is designed to transmit beam end moments and shear forces into the columns without bracing systems to resist lateral loads. These can be straight or tapered. 

The frame stability looks similar to others, but is significantly stronger to hold the vertical loads. The joints connecting are not always fully fixed to either horizontal or vertical members; however when the beam rotates from a vertical load, the columns are able to rotate with it. This allows the joint to rotate as a unit and members maintain the same angular relationships during the rotation. 

Because of this ability, rigid frame structures are highly adaptable and flexible in design. 

Benefits of Rigid Frame Structures

Beyond the clear span of capabilities that offer commercial structures open spaces with no center columns or bracing systems, rigid frame structure buildings retain all the benefits of any metal buildings. This includes:

  • Cost-effectiveness over time
  • Energy-efficient
  • Floors that are not sensitive to vibration
  • Connections perform better in load reversal situations

Are Rigid Frame Structures Right for Your Business?

Rigid frame structures are found in a variety of building styles and uses including:

  • Warehouse facilities
  • Retail stores
  • Plants
  • Clinics and hospitals
  • Commercial units
  • Multi-story buildings of any height

The main reason why rigid frame structures are used for special requirements such as those listed above is that they need to house equipment sensitive to vibrations and deflections. 

Save on cost, and time.

At Fabricon, our modular offices are custom-designed, built in a controlled factory setting, then installed on-site. This unique construction process eliminates any weather-related delays and it also leads to vast savings in time and cost compared to traditional on-site construction. This provides the same functionality and high-quality aesthetics as traditional construction, but in a much more streamlined manner.

Your building is being constructed in our factory at the same time that your site is being prepared for installation. While the design engineering and permitting/approval process may take the same amount of time as traditional construction, by being able to build construction in our factory, and then install on site, the process is speeded up greatly. Our team keeps you informed every step of the way, and you will be surprised at how quickly you will see your project come to life.
