# Structural Analysis Questions and Answers – Analysis of Frames : No Sidesway-II

This set of Structural Analysis Multiple Choice Questions & Answers (MCQs) focuses on “Analysis of Frames : No Sidesway-II”.

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. What will be the value of mAB?
a) 22.9
b) 45.7
c) -45.7
d) -22.9

Explanation: Just substitute the value of rotation at point B in 1st sde equation.

2. What will be the value of mBA?
a) 22.9
b) 45.7
c) -45.7
d) -22.9

Explanation: Just substitute the value of rotation at point B in 2nd sde equation.

3. What will be the value of mBC?
a) 22.9
b) 45.7
c) -45.7
d) -22.9

Explanation: Just substitute the value of rotation at point B and at point C in 3rd sde equation.

4. What will be the value of mCB?
a) 22.9
b) 45.7
c) -45.7
d) -22.9

Explanation: Just substitute the value of rotation at point B and at point C in 4th sde equation.

5. What will be the value of mCD?
a) 22.9
b) 45.7
c) -45.7
d) -22.9

Explanation: Substitute the value of rotation at point C in 5th equation.

6. What will be the value of mDC?
a) 22.9
b) 45.7
c) -45.7
d) -22.9

Explanation: Substitute the value of rotation at point C in 6th equation.

A and C are fixed supports. M acts at point B in clockwise direction. AB = BC = L. EI is constant throughout the frame.

7. This beam is a sway frame.
State whether this statement is true or false.
a) true
b) false

Explanation: This frame is a non-sway frame as due to its shape and geometry, no deflection is possible in any member.

8. What will be the value of FEMBC?
a) 80
b) -80
c) -160
d) 0

Explanation: No force is applied in that part. We will consider moment M for joint equilibrium.

9. What will be the value of FEMCB?
a) 80
b) 0
c) -160
d) 160

Explanation: No force is applied in that part. We will consider moment M for joint equilibrium.

10. What will be the value of rotation at point A?
a) 137.1/EI
b) -137.1/EI
c) 0
d) 100/EI

Explanation: There won’t be any rotation at point A as it is a fixed support.

11. What will be the value of rotation at point C?
a) 137.1/EI
b) -137.1/EI
c) 0
d) 100/EI

Explanation: There won’t be any rotation at point D as it is a fixed support.

12. How many deflection unknowns will be there in this case for which we would need equations?
a) 0
b) 1
c) 2
d) 3

Explanation: Initially, there will be 2 displacement unknowns, but all of them will come out to be zero as it is non-sway frame.

13. How many unknowns will be left finally which are non-zero?
a) 0
b) 1
c) 2
d) 3

Explanation: Rotation at points B will be left finally to be calculated from equations.

14. How many total slope deflection equations will be written in this question?
a) 8
b) 6
c) 4
d) 3

Explanation: 2 members are there and non joint has a zero moment, so there will be 4 sde equations.

15. Which of the following points should be chosen to generate extra equations?
a) B
b) B and C
c) C and D
d) D and A

Explanation: All unknown will come in account if we consider joint equilibrium about joint B.
