H ✓ ✓ ✓ ✓ ✓ ✓ qkN/m QUESTION 5 The steel frame is predicted to be subjected to a uniformly distributed load q, as shown in Figure 1. You are tasked to solve structural analysis problem of the steel structure sculpture as follows: a) Write a general expression in terms of q, L and K for the moments at either point C and F. b) Solve for/determine the vertical displacement at A and B if member AE and BD is found to be damaged. (state any assumptions you have made). c) Suggest the required increased in flexural rigidity of the steel member AGE and BHD to limit the vertical displacement evaluated at (b). Provide detail calculation to support your suggestion. NOTES: YOU MAY USE AS REFERENCE a) choose redundants after taking advantage of symmetric condition solve redundants using flexibility method.. answer will be in variable b) member AE/BD gone, utilised symmetric condition find redundant solve it structure become determinate. use principle of virtual work to find deflection at A or B. c) Find new I (multiplier of k) to show that it can decrease value of displacement from (b). Ex: If at (b) displacement is 100 mm what El value make displacement lesser than 100 mm?
