Abstract: This work focuses on the calculation of shakedown load‐factors of structures by using the lower‐bound theorem of shakedown analysis. The resultant optimization problem is solved by an interior‐point algorithm. In general, the application of shakedown analysis to practical problems leads to large‐scale problems with large numbers of unknowns and constraints. Thus the solution turns out to be computationally intensive. For this reason it is important to reduce the dimension of the considered problem. Therefore, the major improvement of the presented algorithm consists of a problem‐oriented reformulation of the problem reducing the size of the system to be solved.
