The frame is a non-sway frame as due to its shape & geometry
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
View Answer

Answer: b
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
View Answer

Answer: d
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
View Answer

Answer: b
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
View Answer

Answer: c
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
View Answer

Answer: c
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
View Answer

Answer: a
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
View Answer

Answer: b
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
View Answer

Answer: c
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
View Answer

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