This set of Structural Analysis Multiple Choice Questions & Answers (MCQs) focuses on “Analysis of Frames : No Sidesway-I”.
AB = 12m, BC= 8m
Assume EI to be constant throughout. All moment options are given in N-m and all force options are given in N.
FEM represent fixed end moments.
1. This beam is a sway frame.
State whether this statement is true or false.
a) true
b) false
View Answer
Explanation: This frame is a non-sway frame as all supports, member and loading is symmetrical.
2. If value of EI in right frame member was twice that of the left one then this frame will be a sway one.
State whether this statement is true or false.
a) true
b) false
View Answer
Explanation: In that case, members won’t remain symmetric anymore and beams will deflect.
3. What will be the value of FEMBC?
a) 80
b) -80
c) -160
d) 160
View Answer
Explanation: Formula for FEM in this type of loading is 5wl2/96 and direction will be anticlockwise.
4. What will be the value of FEMCB?
a) 80
b) -80
c) -160
d) 160
View Answer
Explanation: Formula for FEM in this type of loading is 5wl2/96 and direction will be clockwise.
5. What will be the value of rotation at point A?
a) 137.1/EI
b) -137.1/EI
c) 0
d) 100/EI
View Answer
Explanation: There won’t be any rotation at point A as it is a fixed support.
6. What will be the value of rotation at point D?
a) 137.1/EI
b) -137.1/EI
c) 0
d) 100/EI
View Answer
Explanation: There won’t be any rotation at point D as it is a fixed support.
7. How many deflection unknowns will be there in this case for which we would need equations?
a) 0
b) 1
c) 2
d) 3
View Answer
Explanation: Initially, there will be 3 displacement unknowns, but all of them will come out to be zero as it is non-sway frame.
8. How many unknowns will be left finally which are non-zero?
a) 0
b) 1
c) 2
d) 3
View Answer
Explanation: Rotation at points B and C will be left finally to be calculated from equations.
9. How many total slope deflection equations will be written in this question?
a) 8
b) 6
c) 4
d) 3
View Answer
Explanation: 3 members are there and non joint has a zero moment, so there will be 6 sde equations.
10. What will be the FEMAB ?
a) 80
b) -80
c) 0
d) 160
View Answer
Explanation: No load is acting on the member AB and same goes for member CD.
11. Which of the following set of points should be chosen to generate extra equations?
a) A and B
b) B and C
c) C and D
d) D and A
View Answer
Explanation: All unknown will come in account if we conserve moment about points B and C.
12. What will be one of the extra condition, which we will get if we conserve moment near joint B?
a) mBA + mCA = 0
b) mBA + mCB = 0
c) mBA + mBC = 0
d) mAB + mBC = 0
View Answer
Explanation: Just cut a small part near joint B and conserve moment around that joint.
13. What will be one of the extra condition, which we will get if we conserve moment near joint C?
a) mBA + mCA = 0
b) mBA + mCB = 0
c) mBA + mBC = 0
d) mCD + mCB = 0
View Answer
Explanation: Just cut a small part near joint B and conserve moment around that joint.
14. What will be the value of rotation at point B?
a) 137.1/EI
b) -137.1/EI
c) 0
d) 100/EI
View Answer
Explanation: Just use both equations as given above.
15. What will be the value of rotation at point C?
a) 137.1/EI
b) -137.1/EI
c) 0
d) 100/EI
View Answer
Explanation: Just use both equations as given above.
