Assignment 2 • You are required to inspect a commercial building. It could be a shopping centre, office tower, educational or transportation facility.

• In your site analysis you are required to explain aspects of design, layout, materials and technologies are used. For examples aspects related to finishes, structures, ventilation, lighting, acoustics, signage, digital wayfinding and accessibility.

• We are looking for mayor design aspects and construction structure and components that define the building. You will need to address if there are benefits with the design, materials used and possibly automation and sustainable technologies.

• Finally you are to explain your view on whether your chosen commercial building is perceived current or obsolete. If your chosen building has been recently completed then you need to future-proof it for the next 10 to 15 years.

• Make use of photographs, diagrams and hand sketches.

Where did it start? •  Discusses Housing styles, urbanization, structures and construction technology.

Identify, sketch or define the Following Forces: • Shear force is a side way force on a building • Shear • Torsion is the twis:ng force on a building • Torsion • Vector force is both magnitude and direc:on force • Vector • Tension is the hanging or pulling force • Tension • Compression• Compression is the pushing force that causes bending

• Concrete

understand forces allows you to understand how things are built in different shapes such as the Mode-­‐Gakuen Spiral in Nagoya, Japan

• Stressing Cables

• Post Tension • Pre Tension • Steel Reinforced

Sub structures • Substructures are the habitable areas below ground and they generally serve a purposed for Foundations, services, maintenance and car parking.

Substructures are concerned with the ground and its form.

• Stability • Water levels • Rock-beds • Load capacities • Sets up the Building and its Behaviour

Structural Loads & Failure •

Structural loads are forces applied to the component of the structure • Structural loads are engineer and in accordance to standards (dependant on Structure, Geographical area and use) • Factors affecting the load: Magnitude, Frequency, Occurrence and Distribution • Failure: • Refers to the loss of load carrying capacity • Initiated when material are stressed, causing fracture or deformation • Load has reached its limit hence the load and capacity is reduced permanently, significantly and quickly

Iden:fy, sketch or define the Following • Loads:

• Dead load: a sta:c (showing liLle or no change) ver:cally downward force on the structure, the self weight of the building and permanent fixtures

– Dead – Live – Dynamic
