# CVE80008 Building Design

## Question:

You have been commissioned to carry out a preliminary design of a 4-storey reinforced concrete building (non-storage) located on a shallow soil site (Class C) in Melbourne for the 1,000 year return period event (Importance Level 3). The building measures 25 m x 25 m in plan and is 16 m tall above the raft foundation.Each story has equal height. The lateral force resisting system consists of momentresisting concrete frames which have ordinary detailing consistent with AS3600.

The centre of mass is offset from the centre of stiffness by 2 m in plan in each direction.Assume the combined dead load and superimposed dead load is 8 kPa for each floor. Imposed load is 4 kPa for typical floors and 1 kPa for the roof. Determine the earthquake design category (EDC) and calculate the following in accordance with AS1170.4 (2007):
Base shear force and lateral force distribution (considering 100% seismic action in one direction only). Noted that a fraction of the imposed action has to be taken into account.
Distribution of bending moment with height assuming the lift shaft walls behave as vertical cantilever members.
Torsional moment at the foundation level (considering 100% seismic action in one direction only).
Approximate distribution of earthquake floor accelerations at each level.
The forces acting on a piece of equipment of weight Wc = 2 kN using Sections 8.2 assuming the equipment is ductile, non-critical and is rigidly fixed to the building at roof level.

Please make clear references to AS1170.4 for any values and equations that you use in the calculation process. 10% of the score is based on clear and professional presentation.
