Section B (Answer TWO of the four questions) Question 3 [25 marks Consider the statically indeterminate frame shown in Figure Q3. Using the Flexibility method by removing the vertical support at node C find the reaction forces at nodes C and D and the bending moments along the frame. The flexural rigidity El is the same for all members. ) Sketch the Primary and the Secondary Structure for the application of the Flexibility Method and define the Compatibility condition; [3 marks) b) Find the displacement at the position of the release in the Primary structure by implementing Virtual Force Method: [8 marks] c) Find the displacement the position of the release in the Secondary structure by implementing Virtual Force Method; [7 marks) a) Apply the compatibility condition to obtain the reactions at the release; and [2 marks] c) Draw the bending moment diagram for the frame. 15 marks) A product integral table is provided on page 9. w kN/m 5m El= const D 4m 7m Figure Q3
