The paper presents experimental research results and their analysis in respect of flat reinforced concrete slabs resting on point supports or soil in case of concentrated punching force. However the conducted researches have shown a number of incompatibilities accepted in computational model standards that appear in the form of critical parameters in the punching zone and configuration of computational (critical) sections in comparison with an actual pattern of slab crack formation and their collapse in the places of concentrated force application. Moreover, the computational methods do not take into account at all an influence of longitudinal reinforcement on both principal axis of the building frame or take it into account this phenomenon by empirical dependence indirectly. In view of the above-mentioned facts an accumulation of new experimental data is considered as an expedient process with the purpose to identify a physical pattern of flat reinforced concrete slabs operation under concentrated punching force. The paper makes it possible to revise a calculative methodology and, preserving a high reliability, it also permits to improve efficiency of a floor construction of the whole framework. It has been determined that longitudinal reinforcement of reinforced concrete slabs is actively involved in their work under concentrated punching force and exerts a prominent influence on their resistance to punching force. The paper presents a possible approach pertaining to evaluation of a longitudinal reinforcement influence on resistance of reinforced concrete slabs to punching force with due account of regulations of the appropriate standardized documents.

The paper describes a circuit of a plant for preliminary grinding of balls made of brittle non-metalic materials. Cubes are used as blanks for the balls. The peculiar design feature of the plant is an inclined location of an abrasive wheel and placement of a charging container having section-shape form in that part of the wheel where a vertical component of linear speed of its points is directed upward. The executed theoretical investigations have made it possible to determine a range of inclination angles of end surface of an abrasive wheel. This range ensures a blank circulation in the charging container. It has been established that the blanks being in contact with the abrasive wheel are slowly moving upward along its inclined end surface and then having reached the maximum top position they are rolling downward along the surface of a slope formed by the blanks. In the machining zone the blanks are making rotary motion and in this case the most intensive rotation is observed in the blanks that are located in the top part of the container. Speed of blank translational motion is small and due to this contact loadings affecting the balls in the grinding process are insignificant and machining process is carried without application of a separator. The paper presents the results of experimental investigations pertaining to grinding of balls made of mineral raw material.

The paper contains description of tool design which is used for rough polishing of balls made of brittle materials. This tool consists of top disk, which is fi-eely set on pouring bearing of the separator shaft, and a bottom disk with elastic coating. Theoretical investigations of ball kinematics have permitted to determine an angular velocity of the balls in the machining zone, value and direction oi slipping speed with respect to the tool.it has been determined that even change of the position of bail rotation instantaneous axis relative to the separator is reached at equality of angular velocities of the bottom disk and the separator. When the top disk is freely set slipping speed is equal for all the balls of the machined lot. When the top disk is stationary slipping speed is significantly increasing however its value becomes variable and depends on ball distance to separator rotation axis.The presented equations of ball dynamics in the machining zone have made it possible to detennine a cohesive force with the bottom disk, frictional forces against the top disk and separator. Recommendations on selection of machining modes at initial and final stages of ball polishing are given in the paper.
