Explain the design steps used in Slope deflection method and moment distribution method.
Answers
Answer:
What is the difference between slope deflection method and moment distribution method?
Slope deflection method and Moment distribution method are both stiffness methods. That is, node displacements are treated as the unknowns, after solving the stiffness equation for displacements, member forces and reactions are obtained. However, Moment distribution method does not explicitly calculate the node displacements, instead, obtains member end forces directly.
Moment distribution method is an iterative method. That is, a fixed set of calculations are repeated several times until the answers converge. The user can determine when the solution has converged depending on the level of accuracy required.
Slope deflection method explicitly identifies the node displacements, sets up the linear simultaneous equations which can be solved to determine these displacements and knowing the displacements, member end forces can be determined. It is the classical stiffness method approach.
