Dissipative theory in the residential buildings pipe-concrete structures study

The pipe-concrete structures stress-strain state and load-bearing capacity abstract theorem are discussed in this article and experimental studies are carried out to confirm them. Pipe concrete structures prototypes were made of high-strength concrete with spiral reinforcement and high-strength longitudinal reinforcement. The developed compressed pipe-concrete structures have increased strength and have high ultimate axial deformations. Significantly greater energy is required compared to traditionally used load-bearing elements to destroy such a structure. This circumstance makes them especially attractive for use in buildings and structures erected in seismically active zones, as well as for unique buildings and structures. The compressed pipe-concrete element design was improved based on the research results. It was possible to significantly increase its strength compared to known analogues due to the high-strength tensile concrete use. Such elements maximum deformation exceeds 1%, which opens up good opportunities for use. The developed structure high strength and ductility indicate that their destruction requires a large energy. It will significantly increase the frames survivability made of using pipe-concrete elements.
