This set of Structural Analysis Multiple Choice Questions & Answers (MCQs) focuses on “Displacement Method of Analysis:General Procedures”.
1. First step in this method is to find stiffness coefficient.
State whether the above statement is true or false.
a) true
b) false
View Answer
Explanation: First step in this method is to write equilibrium equations and find unknown displacements.
2. What is the SI unit of stiffness coefficient?
a) M/KN
b) KN/M
c) KN
d) M
View Answer
Explanation: It is load/force per unit deflection.
3. Which of the following is unknown in this method?
a) force
b) displacement
c) support reactions
d) can’t say
View Answer
Explanation: Displacements are unknown in this method. They are found using stiffness coefficients.
4. Degree of kinetic indeterminacy is used in this method.
State whether the above statement is true or false.
a) true
b) false
View Answer
Explanation: It is true. We use DSI in force method and DKI in this method.
5. Which of the following are not usual places for nodes’ location?
a) joints
b) supports
c) point of change in cross section
d) inflection point of BMD
View Answer
Explanation: Rest all options are usual location for nodes.
6. How many rotations are possible in case of 3 dimensional frame/beam?
a) 1
b) 2
c) 3
d) 4
View Answer
Explanation: Rotations in all 3 directions are possible in 3 dimensional case.
7. How many linear displacements can a node have in a 2 dimensional frame/beam?
a) 1
b) 2
c) 3
d) 4
View Answer
Explanation: It is possible in general X and Y axis.
8. Which of the following methods for solving indeterminate structures are easiest for computational purposes?
a) Force method
b) Displacement method
c) Method of consistent deformation
d) Moment area method
View Answer
Explanation: A and C are same options and deflection method requires less effort.
