Q$2$:

What is the Virtual Work method primarily used for in structural analy ${?}_{8i}?$

A$.$ Determine nodal displacements and rotation.

B$.$ Calculate support reactions.

C$.$ Analyze dynamic behavior.

D$.$ Evaluate member forces and moments.

E$.$ None of the above.

$($B$)($C$)($D$)($A$)$

In the unit load method, what is the purpose of superposition?

A$.$ To simplify the analysis by considering only one load at a time.

B$.$ To combine loads to find the maximum load effect.

C$.$ To distribute loads evenly along the structure.

D$.$ To balance the structure statically.

E$.$ To minimize the deflection of the structure.

$($A$)($B$)($C$)($D$)($B$)$

How does the Virtual Work method handle the effect of support settlements?

B$.$ Ignored in the analysis.

C$.$ Included in joint displacements.

D$.$ Incorporated into fixed$-$end moments.

E$.$ Accounted for in the stiffiness matrix.
