Abstract:
Ultimate loads and deflections permissible in individual members of a continuous concrete structure are dependent on the moment distributions. One of the methods used to determine this distribution is the limit design or plastic analysis. Th i s paper gives a brief presentation of the pertinent features of the plastic theory. It defines essential terms and describes the static, kinematic, and uniqueness theorems which are used in conjunction with the analysis. It also discusses three methods used in determining mo- ment distribution and gives accompanying examples and equations. This is followed by comparisons of concen- trated plastic rotations and deflections for certain specific cases.
