It is indeed true that steel buildings are the most rigid structures that can stand the test of time. However, it is also true that you are required to make the steel building strong so that it can stand tough against extreme weather conditions. So how do you protect your steel building from heavy wind, snow, and seismic forces? The fundamental structural elements of steel buildings are the columns, wall girts, and roof purlins. As a whole, these components are the skeleton of the building that supports the roof and wall panels by providing structural integrity and ensuring a water-tight seal.
Before we move further, it is significant to discuss the dynamic forces that come into play. Imagine a house of cards built from both sides with a roof that does not have any interior structural support. Now it is easy to know how quickly it will topple over with one push. In order to avoid such scenarios in steel buildings, wind framing comes into action. Without the presence of wind framing, the building will be at the mercy of high winds and seismic forces. As a result, the building will sway and flex, which will damage the structure and injure its occupants. Hence, it would be best to remember this fact when planning a project of Commercial Steel Buildings in Kansas.
The common wind framing consists of an ‘X’ pattern of cable or rod bracing, based on the geographical location. The braces are placed after every 100 inches across the length of the building on an average. At the same time, they can be placed on every fourth or fifth bay based on whether your bays are at a gap of 20 inches or 25 inches on the roof and walls evenly.
The most affordable option, yet it needs re-tightening every 3 to 5 years. It is important to consider this factor when you are choosing cable bracing, or else it will reduce overall stability of the structure with time.
Compared to cable bracing, this is much more rigid, has zero stretch, and it is stronger, and it does not need re-tightening. It allows the building a more stable structure that costs a few hundred dollars more per frame. Nowadays, most business owners, as well as engineers and architects, choose rod bracing because it is tougher and can withstand extreme environmental conditions easily.
This bracing type is used when an opening, like a window, garage door, or a walk door, is in a bay where engineering standards require wind bracing. It is actually two vertical members welded to the vertical pillars, which have a horizontal header member attached to the vertical members spanning over the uppermost part of the framed opening. The cost of this portal frame is a few hundred dollars more than the ‘X’ bracing. Nevertheless, it offers flexibility to the building design plan to a great extent.
It is needless to say that engineering and architecture in steel buildings are far more in-depth than traditional buildings. However, for more information, you should talk to a steel building engineer to get more information in this regard.January 11th, 2021 posted by superadmin
