CE 332 Structural Analysis I Name ________________ Fall 2003 Exam II Sec : -------- Problem (1): (i) Define what is meant by a. Carry over factor—give an example. b. Flexibility coefficient, δij—gives an example. c. Distribution Factor—give an example. d. Flexural stiffness, k—give an example. (ii) List three of the guidelines you use when sketching a deflected shape of a structure. (iii) Does Moment Distribution give the exact answers? Explain why?E F G H B C D 12’ 12’ 12’ 12’ 16’ Problem (2): Calculate the vertical deflection at Joint C of the truss shown below if the temperature in members BE, CF and GD was raised by 80F. Use = 6.5 x 10-6 in/in/F and E = 29,000 ksi. Given truss dimensions are in feet.2 k/ft. 4’ 8’ 4’ 8k A B C h 4’ Problem (3): For the beam shown below, calculate a) the vertical deflection at end C b) the slope just to the left of hinge h.
