As the cadet engineer on the project, you are requried to perform the following tasks: 

1. Determine the vertical design actions (self weight, dead load, live load) to be applied to beams along grid lines 

1 and 2. Use the tributary area method to determine the load on each beam in kN/m. [5 marks] 

2. Determine the external wind actions to be applied to the 5 story frames comprisiong beams and columns along 

grids 1 and 2. The design actions should include horizontal wind loads only. [5 marks] 

3. Determine the vertical design actions for a typical slab panel along grid line C (self weight, dead load, live load). 

The width of the panal should be determined using the triburary area method and the load expressed as a kN/m 

line load along the full panel width. [5 marks] 

4. Based on AS1170.0, the designer has determined that two load combinations for ultimate limit state should be 

used to determine the critical design actions on the structure for later use in design: 

Ed1 = [1.2G, Wu, 0.4Q] and Ed2 = [1.2G, 1.5Q] 

Using the unfactored design actions determined in steps 1 to 3, determine the factored design actions applied to 

the frames on grids 1, 2 and the typical slab panel along grid C. [5 marks] 

5. Using the portal method, determine the factored bending moments, shear forces and axial loads for the frame 

along grid 2. The bending moments, shear forces and axial loads should be determined independantly using 

both load combinations for [Ed1 & Ed2] specified in part 4. Note that to determine the moments and forces using 

load combination Ed1, the moments, shear forces and axial loads due to wind loads and gravity loads will need 

to be determined seperately and combined using the principal or superposition. [20 marks] 

6. Using the catilever method, determine the factored bending moments, shear forces and axial loads for the frame 

along grid 2. The bending moments, shear forces and axial loads should be determined independantly using 

both load combinations for [Ed1 & Ed2] specified in part 4. Note that to determine the moments and forces using 

load combination Ed1, the moments, shear forces and axial loads due to wind loads and gravity loads will beed 

to be determined seperately and combined using the principal or superposition. [20 marks] 

7. Assuming that the one way spanning slab panel along grid C is pin supported at all support locations, use 

approximate methods of analysis to determine the bending moments, shear forces for load combination Ed2 = 

[1.2G, 1.5Q]. Use the vertical loads calculated in part 3 in this section. [10 marks] 

8. Using Space Gass, determine the factored bending moments, shear forces and axial loads for the two frames 

along grids 1 and 2 using both load combinations [Ed1 & Ed2]. [15 marks] 

9. Compare the column reactions, maximum and minimum bending moments, shear forces and axial loads 

obtained for frames along grid 2 from the portal method, cantilever method and spacegass. Use tables to discuss 

any differences in accuracy between these methods. Note that the comparison only needs to be made at the 

maximum and mininum moment/shear force locations at the worst story/locations. [10 marks] 

10. The final project report must be a concise, organized, and easy-to-read document. The exact layout and 

table of contents of the final design project report is up to the individual. The report should have enough 

information to assess the accuracy and the approach used for the analysis and appropriate outputs from 

spacegass and hand calculations illustrating the results. [5 marks]
