1. Slope-deflection method is a convenient method for hand analysis of some small structures.
a. True
b. False
2. The slopes and deflections determined by slope-deflection method enable the analyst to easily sketch the deformed shape of a particular structure. The result is that he/she has a better "feel" for the behavior of the structure.
a. True
b. False
3. The name slope-deflection comes from the fact that the moments at the ends of the members in statically indeterminate structures are expressed in terms of rotations and deflections of the joints.
a. True
b. False
4. When a joint in a structure translates, the slopes of the tangents to the elastic curve of the members connected to that joint change.
a. True
b. False
5. For a particular beam, the change in slope is equal to the end moment of the beam when it is loaded with the M/EI diagram.
a. True
b. False
6. If one of the supports of the beam settled or deflected by an amount Δ, the angles θA and θB caused by joint rotation would be changed by Δ/L (or Ψ).
a. True
b. False
7. When span lengths, moduli of elasticity, and moments of inertia are constant for the spans of the continuous beam, the term "2Ek" values are constant and may be canceled from the equations.
a. True
b. False
8. Choose all correct assumptions about the Moment-Distribution Method. Excess or insufficient assumptions means wrong.
a. The structures have members of constant cross section throughout their respective lengths. That is, the members are prismatic.
b. The joints at which two or more members frame together do not translate.
c. The joints to which members are connected can rotate, but the ends of all members connected to a joint rotate the same amount as the joint. At a joint, there is no rotation of the ends of members relative to each other or to the joint.
d. Axial deformation of members is neglected.
9. The carryover moment in MDM states that "a moment applied at one end of a prismatic beam, the other end being fixed, will cause a moment half as large at the fixed end".
a. True
b. False
10. The distributed moments in the ends of the members cause moments in the other ends, which are assumed fixed. These are the distributed moments.
a. True
b. False
