SELECTED PROBLEMS OF INDUSTRIAL CONCRETE

The main function of the ground floor is to transmit static and dynamic loads and to save performance over required time in environment of the influence of different agents. Because of the hard exploitation conditions, together with the influence of different agents that destruct the ground floors, they must fulfill some usable requirements. To fulfill the service life requirements that are connected with the concrete ground floors, they must get the proper structure. To estimate the exertion of the analyzed concrete ground floors, it is necessary to take into consideration the complex state of stresses, which takes palace where the floor slab is subjected to pointed loads. The method, which makes possible to include the complex state of stresses in ground concrete slab calculations and to estimate the level of slab stresses in characteristic, analyzed of Wetergaard`s places objected by loads, has been proposed. That is why only some issues, connected with this topic, are presented in this paper. The model of concrete slab exertion, which makes possible to take under consideration the complex state of stresses in the slab at the place of putting the loads, is proposed. On the basis of considerations, analyses and calculations the method of defining the vertical susceptibility of the subsoil in the function of the subsoil deformation modulus is proposed
