Building Design Assignment: Design of glazing facades
Aim:
This assignment aims to demonstrate the structural design requirements of a glazed façade in a multi-storey building. Among other requirements, the glazed façade is required to comply with Australian Standard AS 2047, Windows in buildings - Selection and installation, which in turn specifies that the glass installed in window assemblies is to comply with Australian Standard AS 1288 Glass in buildings - Selection and installation.
For the purpose of this assignment the only design loads to be considered are the self weight and wind load. The wind loads are to be determined in accordance with AS/NZS 1170.2-2011, Structural design actions Part 2: Wind actions.
Requirements:
You are required to:
1. Determine the design wind pressures (for both strength and serviceability) for the building giving all assumptions made in reaching these pressures.
2. Using the appropriate greatest design wind pressures you have determined, for Option A:
a. Determine the minimum thickness of standard toughened glass to be used in the vision glazing to satisfy both strength and serviceability (assuming the same thickness is used for both the inner and outer glass).
b. Determine if 6 mm heat strengthened laminated glass is used in the vision glazing it will be adequate for both strength and serviceability (assuming the same thickness is used for both the inner and outer glass). If not, what thickness is required?
3. Using the appropriate greatest design wind pressures you have determined, for Option B:
a. Determine the required thickness of the vision glass if it is to be Toughened glass to satisfy both strength and serviceability.
b. Determine the required thickness of the vision glass if it is to be Heat Strengthened Laminated Safety Glass to satisfy both strength and serviceability.
4. Using the design wind pressures you have determined, specify the dimensions required for both the mullions and transoms (depth of section and wall thickness), giving all assumptions made in reaching these dimensions. For this purpose assume:
a. Steel rectangular hollow sections (RHS) to be used for the mullions and transoms. The steel can be C350 or C450 grade. Refer to standard sections and design capacities available on Blackboard.
b. The mullions and transoms sections are not more than 75 mm wide (which is required by the architect) and having a wall thickness of at least 3 mm.
Present your results in a brief report with supporting computations.
