Abstract A bounding technique is proposed to handle non-linear mathematical programming for shakedown analysis of structures. The idea is to divide the original structure into several substructures, each of which can be dealt with respectively. Upper and lower bounds of the limit load factor of shakedown for the original structure can be obtained from similar load factors for each of the substructures. The Melan’s theorem and hybrid stress finite element are used in the programming formulaton and numerical discretization. An elastic-perfectly plastic material is considered here. Numerical applications illustrate the validity of the present technique.
