Which of the following statements about engineered wood is true?

Engineered wood is a category of products made from wood fibers, strands, or veneers that are bonded together with adhesives to form structural components. One key characteristic of engineered wood products, such as I-joists, is their design to maximize strength and minimize material use.

The statement that engineered wood often needs more end bearing than conventional lumber joists is true because engineered wood products are typically narrower than traditional lumber. This means that for proper support, they may require a greater amount of surface area—known as end bearing—on the supports that they rest on. This additional end bearing is essential to ensure that loads are adequately transferred and that the buildings remain structurally sound.

Other options do not hold true in relation to engineered wood. For instance, engineered wood does include structures that incorporate joist hangers, which are used to support I-joists securely. It also can utilize rim joists, especially in areas where walls meet the floor system, to improve overall strength and performance. Therefore, understanding the specific structural requirements and properties of engineered wood helps clarify why the statement regarding end bearing is accurate.
