Structural Analysis Etask 3
The aim of this assessment task is to evaluate the appropriate use of the Force Method for indeterminate structural analysis.
• Students need to complete the eTask and upload the report to Canvas before the due time. Please submit the eTask report (the pdf file) that includes detailed working out.
• eTask2 is due at 11:59pm 8th Oct. Students are expected to plan and manage their time in order to submit this task by the due date.
• If you submit multiple times, only the last submission will be marked. Please make sure that you have submitted the correct file.
Q1 (10 marks). Consider a structure and applied action shown in the figure below. The frame is subjected to a uniformly distributed load on CD, a change in temperature in AB and support settlement at D. Analyse the structure for all actions acting simultaneously and determine
1. The reactions at A and D (5 marks)
2. Bending moment and shear force diagram for the structure (3 marks)
3. Vertical displacement at B (2 marks)
Use the dimensions and load values below.

Q2 (10 marks). Consider the structure and applied actions shown in the figure below, which is derived from Q1 by making joint A fully fixed. The frame is subjected to a uniformly distributed load on CD, a change in temperature in AB and support settlement at D. Analyse the structure for all actions acting simultaneously and determine
1. The reactions at A and D (8 marks)
2. Bending moment diagram for the structure (2 marks)
Use the structural dimensions and section properties listed below.
