**AST 212** - **BEAM DEFLECTION** Refers to the **movement of a beam or node from its original position** due to the forces and loads being applied to the member. - **BEAM** A structural element that **primarily resist loads applied laterally to the beam's axis**. An element designed to carry primarily axial load would be a **strut or column**. - **DEFLECTION** The **degree to which a part of a long structural element such as beam** deformed laterally under a load. - **BENDING MOMENT,** it is produced by a **transverse load applied to beams, the simplest case is the cantilever beams.** - **CURVATURE OF A BEAM** It is **the CENTRAL** to the understanding of beam bending. - **WOOD, FIBER GLASS, STEEL, AND CONCRETE** Common materials used in composite beams. - **CONCRETE AND STEEL** A composite beam that is **made up of various beams** be it structural members. - **BETTER ADAPTABILITY** A composite beams that can be **used in variety of environments, including high traffic areas.** - **RESIN** A **non-wood-based material** - **BETTER DURABILITY** A composite beam that **is more resistant to termite damage than traditional timber beams.** - **LESS BLIGHT ON THE NATURAL LANDSCAPE**. A composite beam that is **far less disruptive** compared to the traditional timber beams. They are usually used in **lowlighted or remote locations.** - **AVAILABLE IN A VARIETY OF DESIGN STYLES** A composite beams **used in a variety of deigns**. - **MOMENT-AREA METHOD** It uses **divided by the flexural rigidity diagram** of a beam to determine the deflection and slope. - **CONJUGATE BEAM METHOD** It is **defined as a fictitious beam whose length is the same as that of the actual beam** - **BUCKLING** A change in **geometry of structure under compression** that results in its ability to resist load. - **COLUMN** It is a **vertical member that carries a compressive axial load**. - **INELASTIC BUCKLING** **a column with intermediate length**, - **TORSIONAL BUCKLING.** A type of failure is caused by **TWISTING** about the longitudinal axis of the member.
