South Australian Drill Core Reference Library Assignment

1. PROJECT BACKGROUND
The South Australian Drill Core Reference Library hosts geological samples recovered from over 130 years of exploration for minerals and energy resources in South Australia. These irreplaceable samples represent valuable direct records of the geological materials retrieved from the depths of the crust, which will continue to be investigated and analysed by new generations of geologists in industry, research, education and government. The facility consists of three main areas, that vary in use and their design and construction methods; the hylogger, the library and the administration building. The facility was constructed in 2015 as part of the Tonsley Redevelopment, Clovelly Park.
 

2. PROJECT SCOPE
The scope of this project is to design and document some of the main structural roof and floor elements for the Administration Building of the State Drill Core Library Facility. The focus will be on the part of the building located between Grids BA and BF, B1 to B11 on Structural Drawings ST-200, ST-303 and Architectural Drawing A128.
Firstly determine the design loads on the building (remember to consider the whole building for wind loads) and then design the structural framing members using steel and then timber.
The structural elements you will be designing are a roof beam, first floor beam, column, lateral bracing system and a connection detail (for bonus marks).
The following items are not in the scope of this project:
• Any concrete elements including the design of the first floor slab
• Earthquake design
• Fire resistance design
• Ground floor slab or footing design
 

3. DESIGN CONSTRUCTION – ADMINISTRATION BUILDING
a) Ground and first floor exterior walls: Lightweight stud wall or glazing with aluminium composite façade panels supported on steel framed fascia trusses. Refer to Architectural drawing A202 for details.
b) Roof: Metal sheeting with insulation under, on steel purlins and rafters as shown on the architectural drawings A303 and A630.
c) Floors: The first floor is a reinforced concrete one-way slab 120mm thick supported on steel beams and columns. The ground floor is an industrial raft slab on ground with pad footings.

Roof Bracing design: Building section stability under wind
• Determine the maximum tensile and compressive forces in the roof bracing truss between grids B1-B9 and BB-BC in each orthogonal wind direction, include your Spacegass INPUT and
OUTPUT for review
• Critical tension member design (EA or UA)
• Critical compression member design (CHS)
Roof Beam design RB89 (UB) between truss T1 on Grid B3 & truss T2 on grid B5:
• Determine design loads and actions (shear and bending) for strength
• Strength design - member moment capacity (incl. effective lengths) for worst up and down load combinations, for positive and negative moments
• Serviceability Design
