| Title of the article | Problem tasks of development of hypotheses of mechanics of destruction in relation to calculation of ferroconcrete designs |
| Abstract. | Approaches for an assessment of tensely deformed condition of ferroconcrete designs from a position of development of hypotheses of mechanics of destruction are offered. Offers on creation of the settlement device of reinforced concrete are provided in article by allocation of the two-console element including a crack. Communication between such parameters as intense deformed conditions of cross section of a ferroconcrete element and features of coupling of fittings and concrete in the zones adjacent to a crack therefore the new solution of a task about intense the deformed condition of ferroconcrete designs in the zone which is directly adjacent to a crack can be received is revealed. It is shown that the pliability of a two-console element is connected with movements of all ferroconcrete core, and, therefore, the interrelation of the first and second limit states is traced. The analysis of dependences «power influence – movement» is made for impacts on the allocated two-console element. The conclusion is drawn on expediency of the offered statement of a considered problem which will allow, even remaining within V.I. Murashev's traditional model, considerably to specify key parameters of reinforced concrete and to explain many phenomena noticed in experiments occurring at resistance of reinforced concrete to power and deformation influences. |
