1 – Learn a structural analysis software Robot or program of your choice (e.g. Robot, StaadPro or SAP 2000 or RISA 2D). Use available demos and training resources. You will be provided an introductory session to Robot and you need to learn only the analysis module.
This is a free and easy one: https://structural–analyser.com/ with a tutorial by an ex–student

2 – Study portal and cantilever approximate frame analysis methods from your textbook (Chapter 12). Also, read Chapter 17 on Structural Modeling and Computer Analysis.
3 – Solve the frame shown using both portal and cantilever methods. Compare your results for both methods to exact analysis using Robot or program of your choice. Assume baseplate connections as fixed support. All bays are 15–ft wide. First floor is16–ft high and the top two are each 12–ft high.
- a) Assume columns and beams have A = 50 in2, and I = 500 in4,
- b) Repeat part (a) assuming beams moment of inertia is increased to Ibeams = 2,100 in4. Columns remain as Part (a).
- c) Repeat part (a) assuming beams moment of inertia is decreased to Ibeams = 60 in4. Columns remain as Part (a).
Discuss results in terms of shear, and moments in various members and overall frame deflection. By deflection discussion it is meant how it relate to the moment diagram.
