STRENGTH OF INCLINED CROSS-SECTIONS OF REINFORCED CONCRETE PROTECTIVE SHELLS UNDER THE ACTION OF PUNCHING

The experience of inclined cross-sections in the zones of influence of transverse forces and punching loads has been studied. The results of experimental studies of inclined cross-sections of protective structures in the area of influence of local emergency load on punching are presented. The article presents the reinforcement and strength of inclined cross-sections at the angle of destruction γ=40°. The analysis of the results was carried out and recommendations were developed for the design of inclined cross-sections of shells in the punching zone.
