Laminated Veneer Lumber – A composite of wood veneer sheet elements with wood fiber primarily oriented along the length of the member. Veneer thickness shall not exceed 0.25”.

Light-Frame Construction – A type of construction whose vertical and horizontal structural elements are primarily formed by a system of repetitive wood or light gage steel framing members.

Live Loads – Those loads produced by the use and occupancy of a building or other structure and do not include construction or environmental loads such as wind load, snow load, rain load, earthquake load, flood load or dead load.

Live Loads (Roof) – Those loads produced (1) during maintenance by workers, equipment and materials; and (2) during the life of the structure by movable objects such as planters and by people.

Loads – Forces or other actions that result from the weight of all building materials, occupants and their possessions, environmental effects, differential movement and restrained dimensional changes. Permanent loads are those loads in which variations over time are rare or of small magnitude. All other loads are variable loads.

Load Effects – Forces and deformations produced in structural members by the applied loads.

Longitudinal Reinforcement – Reinforcement placed parallel to the axis of the member.
