The method of additional loads is used for non-linear finite element analysis of reinforced concrete structures. The main difficulty of realization of this method programs is the definition of theoretical functions for formation of additional loads and correcting stresses. For example, the algorithm for formation of additional loads was carried out for taking into account of progressive cracking on the basis of developed triangular finite element with conditional crack. This algorithm was realized in program “Element-1”, which gave the good results for analysis of some structures under plane stress-strain state. Besides this algorithm has opened the possibilities for formation of additional loads for any structure and non-linear property. It was proved by finite element analysis of Chelyabinsk shopping center long-span shell.
