Straight Column Steel Building

Let’s discuss the Straight Column Steel Building. All types of prefabricated buildings have different requirements. As discussed in this series on steel framing, choosing a clear span or modular span framing is the first step. That determination is based on size, application, and budget for the project.

Oriental PEB  prefabricated steel buildings use “rigid-frame” framing. Also known as “red-iron” because of the red-oxide paint on the steel, these structures are manufactured to be Oriental Peb.

7 TYPES OF  STEEL BUILDING FRAMES

Oriental Pre Engineered Building uses seven basic types of prefabricated buildings, as you can see in the illustration. Each of the blogs in this series will discuss the strengths of one of these steel-framing methods.

We begin with basic straight column prefabricated steel framing.

WHY PEOPLE CHOOSE STRAIGHT COLUMN STEEL BUILDING?

Many people choose a Straight Column structure because the SC Structure will help them in interior finishing. Doing interior on a straight column structure is easier than doing interior on a tapered column framing system. The straight walls maximize usable floor space. The minimum horizontal loads of a straight column system often save money on slab foundations, as well.

Straight column frames are generally used in structures up to about 80’ wide. However, building widths over 40’ are sometimes more economical with tapered column framing. If your structure is to be 50’ or more, you may want to have the building quoted both ways to evaluate your options.

Straight column framing works great for small offices or other free-standing commercial or retail operations. They are also popular with restaurants and other businesses where maximum use of interior space is important.

Types of FrameWorks In Steel building construction

MODULAR FRAMEWORK

Modular frame designs are used for extra-wide buildings that clear span design isn’t suitable. The modular framework provides interior columns to support the greater width of the roof. The load is more evenly distributed, reducing the value of the frame and therefore the foundation of extremely wide buildings.

Modular framework designs are generally utilized in factories and other very large structures and in buildings where a wide-open, clear span isn’t required.

FRAME TYPES

The mainframe refers to a rigid-frame steel building with a backbone of I-beam mainframes. Each frame is made from two or more columns supporting a rafter running laterally from one side of a building to the opposite. The frames are spaced between the 2 end walls and bear a majority of the building load.

Endwall frames support half the load of the mainframe in most steel buildings and are similar in design to mainframes. the top wall frame is often built using light beams to save lots of costs unless there are plans to expand the building within the future.

Single slope frames have different eave heights on each sidewall. The roof slopes upward from front to back, creating the design of a house cut in half along the vertex. Retail centers and strip malls are often created using single slope frames.

Lean-to frames are similar in appearance to single slope frames, but they’re not free-standing. A lean-to frame relies on the mainframe of a separate, free-standing building together of its sidewalls.

SECONDARY FRAMING

The frame types above are all primary framework. Secondary framing provides support for the wall and roof panels, and carry little of the building’s overall weight. The secondary framework also transfers loads to the first frame to stabilize the structure.

Girts are the secondary spanning members for paneling connection. they will run flush with the column on an end wall, also referred to as an inset or flush mount, on sidewalls they will overlap on the surface, referred to as outset or bypass.

Purlins are the secondary spanning members for roof panel connection.

Your steel building design begins with the intended size and use of the building. If the intended use requires clear sightlines and wide open floor space, a transparent span frame is very recommended. If you would like a particularly wide building and may accommodate interior columns, a modular frame will do the work.

For smaller retail and office spaces, you’ll consider single slope frames while a lean-to can increase space on a lower level or act as additional storage.

The perfect frame is out there for any steel building. Armed with the knowledge of the varied sorts of frames, you’re able to go forth and style your perfect steel building.
