Constructing Logbook WEEK 6 Jiawei CHEN
Tutorial Activities (In-‐Situ presentation) • Site : Ascot Vale • Using timber frame system as the frame of the house • Triple glasses for windows • The retaining wall combined with metal “I” beams and timber beams with
fixed joints to stabilize the whole system.
Tutorial Activities (In-‐Situ presentation) •
Site : South Melbourne
•
Wall Systems:
External: Masonry veneer construction, internal: stud wall framing •
Floor System:
Steel used as primary beams, prefabricated wood steel joists used as lumber •
Roof Structure:
old truss used as primary load bearing structure.
Tutorial Activities (In-‐Situ presentation) • Site: North Melbourne • Material used for studs in wall framing: pine wood • Concrete wall (filled with cement and steels every 2 metres)
Tutorial Activities (Model presentation) • Pins were used to connect the steel beams for
the purpose of stabling the structure of the canopy model. Pins serves as bolts in the actual canopy.
Summary of Learning-‐loop • Plate structures: Rigid, planar, usually monolithic structures that disperse applied loads in a multidirectional pattern, with the loads generally following the shortest and stiffest routes to the supports. Can be envisioned as a series of adjacent beam strips interconnected continuously along their lengths • Ferrous: iron (relatively cheap) • Non-‐Ferrous: all other metals (generally more expansive), less likely to react with oxygen • Alloys: combinations of two or more metals • Water related damage: Oxidation Corrosion • Protection against water to reduce corrosion: - avoid prolonged exposure to moisture - seal against moisture - chemical treatment • Flat roofs: pitch 1 degree to 3 degree • Pitched and sloping roofs: pitch >3 degrees low slope <15 degrees, medium slope 15 to 30 degrees, high slope 30 to 45 degree • Concrete roof • Structural steel framed roofs: Flat structural steel roofs Sloping structural steel roofs • Trussed roofs • Light framed roofs: Gable roofs Hip roofs
Glossary • •
Rafter: the main structure members in the frame of roof system.
• Purlin: “a horizontal beam that provides intermediate support for the common rafters of a roof construction.” (Collinsdictionary.com, 2014).
• Cantilever: a structural element supported at only one end. (Newton, 2014). •
Portal frame:
•
A type of roof frame consist of a series of braced rigid frames with purlins for the roof and girts for the walls. (Newton, 2014).
• •
Eave: The part that extends beyond the wall of a building. (Collinsdictionary.com, 2014).
• Alloy: a combination of 2 or more metals. (Newton, 2014). • •
Soffit: “the underside of an overhanging roof eave”. (Ching, 2013).
• Top chord: “ principal member of a truss extending from end to end and connected by web members.” (Ching, 2013).
