Structural engineering is the design and analysis of structures that support or resist loads. In the construction industry, wood is a common material used in structural engineering. Here are a few types of structural engineer wood:

1. Lumber: Lumber is a type of structural engineer wood that is cut from trees and used for construction purposes. It is available in a range of sizes and grades, and is commonly used for framing, sheathing, and other structural purposes.
2. Glulam: Glulam, or glued-laminated timber, is a type of engineered wood that is made from layers of dimensional lumber that are bonded together with adhesives. It is strong, durable, and versatile, and is commonly used for long-span beams and other structural elements.
3. LVL: LVL, or laminated veneer lumber, is a type of engineered wood that is made from thin layers of wood veneer that are bonded together with adhesives. It is strong and stable, and is commonly used for beams, headers, and other structural elements.
4. CLT: CLT, or cross-laminated timber, is a type of engineered wood that is made from layers of lumber that are bonded together with adhesives. It is strong and stable, and is commonly used for floors, walls, and roofs in multi-story buildings.
5. PSL: PSL, or parallel strand lumber, is a type of engineered wood that is made from strands of wood that are bonded together with adhesives. It is strong and stable, and is commonly used for beams, columns, and other structural elements.

These are just a few examples of the types of structural engineer wood that are available. It's important to choose a wood that is appropriate for the specific structural needs of your project.
