Estimation of Upper and Lower Bound Limit Loads and Shakedown Load for Structural Frames based on Reduced Modulus Approach

In this paper, the elastic compensation method proposed by Mackenzie is used to estimate the upper and lower bound limit (collapse) loads and the upper and lower bound shakedown loads for some practical problems in structural analysis, such as:beam, pressure vessels and etc. The method is based on iterative elastic analysis procedure and application of the lower and upper bound limit load theorems.
