Question 3 The uniform rigid-jointed rectangular portal frame ABCDE, as shown in Figure Q.3, is pinned at A and E and supports collapse loads as indicated. Using the information provided, attempt the following: 6Determine the number of possible hinges and Independent mechanisms (3) (ii) Use the plastic analysis (Kinematic) method to determine the required value of the plastic moment of resistance (Mp). (14) (i) Determine the reactions and sketch the collapse bending moment diagram and indicate the salient values (12) (iv) If the pin supports at A and E are replaced with fixed supports, how does this change the number of possible hinges and independent mechanisms? (6) Total marks = 35 1 20 kN/m 12 kN D C 2 m 6 KN B 2 m 1 E 6 m
