Exploring The Features, Applications, And Benefits Of Bowstring Roof Trusses
The role of roof trusses in ensuring stability in residential and commercial structures is well documented. However, the sheer variety of roof trusses makes it complicated to choose the right one for a particular application. In this blog, the focus is on a bowstring roof truss, its features, myriad applications, and benefits.
What Is A Bowstring Roof Truss?
A bowstring roof truss is a type of truss characterized by its bow-shaped design. This shape is created by the roof truss design, wherein the top chord is curved and the bottom chord is straight, resembling a bow.
Features Of Bowstring Trusses
- Curved Top Chord: The roof truss features a curved top chord as mentioned above. This not only gives it a distinct shape but also makes the overall structure more aesthetically pleasing.
- Flat/Straight Bottom Chord: The bottom chord, by comparison, is straight. The reason behind this is structural, as it offers resistance to the arch of the top chord.
- Web Members: The web members connecting the top and bottom chords are either vertical or diagonal. These web members ensure that the load is distributed evenly throughout the roof truss.
- Made of Wood: Most bowstring roof trusses are made of wood by using singular timber boards and joining them together to create chords. These boards are held together with the help of steel bolts.
- Large Span: Due to the roof truss design of this particular design, it can cover a large span or area. Therefore, they are best-suited in cases where there is a large, unsupported roof.
Applications And Benefits Of Bowstring Roof Trusses
Perfect For Large Spaces: Since the span covered by a bowstring roof truss is large, it is used to support large and open roof spaces such as hangars, stadiums, warehouses, or other similar structures.
Aesthetic Appeal: The curved appearance of the top chord is considered aesthetically pleasing, making it an additional bonus.
Efficient Use of Materials: Due to the roof truss design, it is considered lightweight in nature and uses fewer materials to manufacture. This not only makes it better from a raw material standpoint, but it also makes it a cost-effective solution without compromising on proper load distribution.
