Trusses vs. Conventional Rafter Framing: Which is Better?
Why are trusses more commonly used over conventional rafter framing?
a. because trusses are stronger over long spans
b. because trusses require less end bracing
c. because trusses are cheaper
Final answer: Trusses are more commonly used than rafter framing because they are stronger over long spans, require less end bracing, and are often cheaper.
Answer:
Trusses are more commonly used over conventional rafter framing for several reasons. Let's explore why trusses have become a popular choice in construction.
Trusses are preferred over conventional rafter framing for their superior strength over long spans. The triangular structure of trusses allows for even distribution of load and greater resistance to bending, making them ideal for large-scale constructions and buildings.
In addition, trusses require less end bracing due to their internal diagonal members that provide rigidity. This reduces the need for additional support structures and simplifies the construction process.
Furthermore, trusses are often more cost-effective compared to conventional rafter framing. They can be pre-designed and prefabricated off-site, leading to streamlined construction processes and lower labor costs.
Moreover, trusses offer flexibility to adapt to changes in temperature, motion, and load. This adaptability is crucial for preventing structural damage and ensuring the longevity of the construction.
