The questions of ensuring the survivability of structural elements of buildings taking into account beyond-design effects, as well as the need to assess their loading under conditions of possible local damage are considered. This paper shows an energy algorithm for the study of physically nonlinear formulation of damaged objects, taking into account the features of finite element analysis of the bearing systems. The essence of the proposed approach is given by the example of a material point resting on a spring with nonlinear stiffness. The efficiency of this technique is tested on the example of a four-span beam. The method of determination on the basis of finite-element analysis of the maximum load of construction systems under beyond-design influences with regard to the physical nonlinearity of deformable objects is developed. The recommendations on the use of the given computational scheme in assessing the survivability of metal structural elements with possible local damage are given.
