Which wooden structural member is formed by gluing and laminating multiple short pieces of lumber under pressure to create a long, strong beam?

• A. Glue-Laminated Beam
• B. Gusset Plate
• C. Hollow-core door
• D. Hybrid Modular Structure

Answer: (A)

A glue-laminated beam is an engineered wood member created by bonding multiple shorter pieces of lumber with adhesive and pressing them under controlled pressure to form a single, long, strong beam. This lamination distributes loads across many fibers, giving greater strength, stiffness, and span capability than a solid piece of natural lumber. That exact description matches the concept of a glue-laminated beam, which is why it’s the correct choice. The other options refer to different components or structures: a gusset plate is a metal connector used in trusses, a hollow-core door is a door with hollow spaces, and a hybrid modular structure is a general construction concept not specifically about laminated wood beams.
