Part C Given: y = 200 MPa all members - pefectly plastic (no hardening) Beams-Rectangular cross-sections: height=40cm, width = 20 cm Columns - Square cross-sections: height = 20cm 1. Using ANSYS,

simulate the behavior of the frame shown for λ = 1, 1.25, 1.5, 1.75 and 2.0. Document your result by providing snapshots of the moment diagrams for A-1.25. Do all the simulations converge? 2. From the ANSYS results, identify the interval for the collapse load factor (I.E. between what 2 lambdas). 3. From the ANSYS simulations, identify where and in what sequence do the plastic hinges form. 4. Based on the location of the plastic hinges, use manual calculations to estimate the collapse load factor 5. Manually sketch the bending moment diagrams of beam DE at the collapse load
