What type of drawing features a web steel joist?

The correct answer is structural drawings, as they specifically depict the framework that supports a building or structure. Web steel joists are essential components in structural design, typically used to support floors and roofs. These joists feature a series of triangular webs that provide strength while minimizing material use and weight.

Structural drawings provide the necessary details for construction, including dimensions, load-bearing specifications, and the connections of various structural elements, making them crucial for ensuring the integrity of the building. They provide a comprehensive view of how these components fit into the overall design.

In contrast, electrical drawings focus on the wiring, electrical systems, and lighting setups of a building. Architectural drawings illustrate building layouts, finishes, and aesthetics, while mechanical drawings deal with HVAC systems, plumbing, and other mechanical installations. Each of these other drawing types serves different functions within the construction process and does not center around the detailed specifications of structural elements like web steel joists.
