Description and Classification of structural System & Graphic Structural Diagrams Foundations & Footings: Concrete Blinding Piers

Secondary Structure: Timber Frame Structure-Roof structure (joists)

Strip Footing

Pad Footing

Rafter Primary Structure: Exposed Aggregate Concrete – Floor system Columns – supports roof Timber Frame Structure – Roof structure (beams)- Horizontal primary structure

Identification, Description and Location of Structural Materials

Brickwork- Clay Brick- Wall, column

Timber- Pine for rafter, stud wall, batten; LVL for ceiling joist Steelwork- For Roof Framing, beam, column, door header; reinforcing bar in foundation, bolting, connection, corrosion protection

Concretefooting, slab, wall <-pre cast concrete, concrete cover for columns, beams, footings


Joints Butt joint- â&#x20AC;&#x153;butt joints extend the length or width of a part by connecting the edges of two pieces of material in the same plane â&#x20AC;?

Pinned joint

Sawcut joints - benefits: Consistent joint dimensions (same width and depth at each cut) Straight, clean cuts Good joint filler performance Cost-effective concrete placements of any size


Weld- “To join (metals) by applying heat, sometimes with Screw-

pressure and sometimes with an intermediate or filler metal having a high melting point.”

ConcreteNail-

Bolts- “A fastener consisting of a threaded pin or rod with a head at one end, designed to be inserted through holes in assembled parts and secured by a mated nut that is tightened by applying torque”
