What is the typical type of truss used to support a sloping roof?

The typical type of truss used to support a sloping roof is the pitched chord truss. This truss design features sloping top chords that provide the necessary support for roofs with a slope, allowing for the efficient distribution of loads from the roof down to the walls. The geometry of a pitched chord truss is specifically advantageous for applications where a sloping profile is required, such as in residential or commercial buildings with gabled roofs.

In contrast, platform frame construction refers to a building method that uses horizontal framing components rather than trusses to support roofs, which does not directly relate to the truss type used for sloping roofs. A simple beam, while capable of supporting loads in various applications, lacks the structural design needed for effective roof support in sloped scenarios typically managed by trusses. Rafters, though they are commonly used in sloped roof constructions, do not encompass the broader truss system that includes trussed designs providing enhanced strength, stability, and load distribution in comparison to rafters alone. Therefore, the pitched chord truss stands out as the most suitable choice for supporting sloping roofs.
