Please make assumptions where need be, thank you

Question 2 (25 marks) A simple five-storey (including roof) residential building is to be constructed on Shallow soil in Adelaide. The structure is made of reinforced concrete. In plan, the building is 9 m x 6 m. Dead load of 10 kN/m2 applied on the floors and 3 kN/m2 on the roof. Floor and roof live loads are 3 kN/m2 and 1 kN/m2, respectively. Storey height: 4.0 m each. (a) Determine the earthquake design category (5 marks) (b) Determine the earthquake base shear (10 marks) (c) Determine the vertical distribution and horizontal shear force distribution over the height of the building. If you have not been able to work out the base shear assume it is 600KN. (NOT the correct value) (10 marks) Question 2 (25 marks) A simple five-storey (including roof) residential building is to be constructed on Shallow soil in Adelaide.
