Q: Which of following statements is NOT true for moment distribution method?
  • A. It is also called a 'relaxation method' and it consists of successive approximations using a series of cycles, each converging towards the final result.
  • B. Moment distribution is suitable for the analysis of specific types of indeterminate beams only and not for rigid frames.
  • C. Moment distribution is an iterative method of solving an indeterminate Structure.
  • D. The moment distribution method was first introduced by Hardy Cross in 1932.
Correct Answer: Option B - Moment distribution method– • The moment distribution method was first introduced by Hardy Cross in 1932. • This is an iteration procedure. To start all joint in a beam or frame are considered fixed, and given loading applied on this modified structure. • Moment distribution is suitable for the analysis of specific type of indeterminate beam and rigid frame. • It is also called a relaxation method and it consist of successive approximations using a series of cycles, each converging towards the final result.
