TUTORIAL AND WORKSHOP
Summary: SHORT AND LONG COLUMNS: Short columns: Ratio of effective column length to the smallest cross section is less than 12:1 Long columns: Ratio of effective column length to the smallest cross section is larger than 12:1 WALL SYSTEMS: Structural frames: • Concrete Frames (use a grid of columns with concrete beams connecting columns) • Steel Frames (use a grid of steel columns connected to girders and beams) • Timber Frames (Post and Beam) Load Bearing Walls: • Concrete • Masonry Stud Walls: • Light Gauge Steel Framing (use smaller sections to meet the structural demands) • Timber Framing (use smaller sections to meet the structural demands) Timber is seasoned to adjust the moisture content for the intended use. ENGINEERED TIMBER: SOLID LVL—(LAMINATED VENEER LUMBER): mainly structural (beams, posts, portal frames) GLULA -‐-‐-‐ GLUE LAMINATED TIMBER: mainly structural (beams, posts, portal frames) CLT-‐-‐-‐CROSS LAMINATED TIMBER: uses: structural panels (horizontal and vertical) ENGINEERED TIMBER: SHEET PRODUCTS Plywood: structural bracing, structural flooring, formworks, joinery, marine applications MDF-‐-‐-‐ MEDIUM DENSITY FIBERBOARD: non-‐structural applications (joinery) CHIPBOARD & STRANDBOARD: cladding finish (bracing), as part of structural systems ENGINEERED TIMBER: OTHER MANUFACTURED PRODUCTS I-‐Beams: suitable for medium spans, uses: floor joists, rafters Box Beams: suitable for larger spans, uses: floor joists/rafters Timber flanged Steel Web Joists: uses: floor joists/ rafters
Glossary: Stud: a vertical member in the timber wall framing. (Newton,2014). Nogging: a horizontal member used to prevent the buckling of studs in the timber wall framing. (Newton,2014). Lintel: a horizontal beam over a door or a window. (Collinsdictionary.com, 2014). Axial Load: the load along the axis. Buckling: Seasoned Timber: Wood that has been dried to adjust the moisture content for the intended use. (Newton,2014).
