Founda'ons & Foo'ngs:
Concrete Blinding Piers
Strip Foo'ng
Pad Foo'ng
Descrip(on and Classifica(on of structural System & Graphic Structural Diagrams
Primary Structure: Exposed Aggregate Concrete – Floor system Columns – supports roof Timber Frame Structure – Roof structure (beams)
Secondary Structure: Timber Frame Structure-‐Roof structure (joists) Roof SheeCng
Identification, Description and Location of Structural Materials
Hatching
Concrete
Timber
Steel
Clay Brick
Joints
BuG joint-‐ “buG joints extend the length or width of a part by connecCng the edges of two pieces of material in the same plane ”
Pinned joint
Sawcut joints -‐ benefits: Consistent joint dimensions (same width and depth at each cut) Straight, clean cuts Good joint filler performance Cost-‐effecCve concrete placements of any size
Bolts-‐ “A fastener consisCng 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 Cghtened by applying torque”
Weld-‐ “To join (metals) by applying heat, someCmes with pressure and someCmes with an intermediate or filler metal having a high melCng point.”
Screw-‐
Nail-‐
Concrete-‐
Sustainability and environmental anlysis Steel Concrete Timber brick
Carbon Footprint-‐
High high lowest High
Recyclability-‐
High-‐ without loss of performance
Only for uncontaminated concrete -‐crushing, pre-‐sizing, sorCng, screening and contaminant eliminaCon
High-‐ High-‐ crushing and reuse, but not very common
