Which type of truss is becoming less common in modern construction?

The bowstring truss is becoming less common in modern construction primarily due to changes in architectural design and advancements in building materials that favor more efficient structures. Originally, bowstring trusses were popular for their ability to span large distances with a curved shape that offered aesthetic appeal and effective load distribution. However, modern construction increasingly relies on alternative framing methods, like steel frames and engineered wood products, which can provide similar or improved structural performance without the complexities that bowstring trusses entail.

Additionally, the manufacturing and assembly processes for more modern trusses often result in lower costs and quicker build times, making them more attractive for contemporary projects. These factors contribute to the decline in the use of bowstring trusses in favor of newer, more efficient structural solutions that meet the demands of today’s building codes and design preferences.
